  1. I will let you know. Thanks for your help,. Kelly, Have they inspect the reservoir? Most of the time your reservoir is dirty and it will no allow fluids circulate through the system. JP Importz
  2. Hi there, I've successful convert many R-12 system to R-134 with no problem. Many folks giving it a bad rep because they wouldn't take the time to do it right or lack of knowledge how the a/c works. This vehicle actually designed for R12 so it will work much better with R-12 but where can we find R-12? The gray market? We have seen 104 degree here in the Dallas, TX area the past week. I've convert a couple of them last week, air blows 28 degree out of the vents in 104 degree temp. Here are some tips: - Flush the system Flush the system, actually..?? Or do you really mean pump it down to a HARD vacuum..?They sell the flushing chemical at any a/c supply outlet. What do you mean why pump it down to a HARD VACCUM? Is this how you flush the system? - Replace all the 0-rings and lube them up with oil Why...?? My seals have worked for 150,000 miles... And with what oil...??Once you open up the lines, It's wise to replace the 0-rings. We had a quite a few 0-rings after the convertion. - Use the right oil for your a/c system Wouldn't the "right" oil for the system mean being compatible with the original R-12..?? Would be surprise what kind of oil people will put in the a/c system. - Replace the drier once the system is open up First pump it down to a HARD vacuum, undoubtedly removing ALL the H2O, and NOW remove the drier..? Why? Since you asked me this question, I don't think you ever work on an a/c system before - Recharge the proper amount of oil Doesn't the commercially packaged for retail R-134 come with the oil mixed in...??Nope - Recharge the proper of R-134(usually 10-15 less than your R-12 system) Or simply recharge to the level that results in the proper low side pressure, ~40 lbs, as directed in the DIY kit..! - Last but not least converting the system isn't cheap. Bring it to someone has the knowledge. Pay for the reapair Once not Twice!!! $50 for the DIY kit including 32 oz of R-134, ~$100 for a reputable A/C specialty shop to do it. Key words = REPUTABLE & A/C SPECIALTY SHOP...! JP Importz

  4. Yes, we vacuumed it for approx 30 min befor charging. We added about 3 ounces of PAG oil. Have you had a chance to put on the new compressor? Keep us updated. JPI
  5. Are you familiar with the Direct Port Injection system? What kind of fuel controller are going to use? This is a very high compression engine. JPI
  6. Have you inspect your shims on the clutch? I would transfer all the old shims to the newer compressor. When you said you properly charge the system, How much did you charge? What was the low and high pressure? What is the temp ? I would need these information. JPI
  7. There are only 2 brake sensors. They are located on the passenger side. JPI
  8. Hi Ted, I would check all the connections one more time. Make sure you don't pinch the wires when putting the cover back on. It wouldn't hurt to inspect coils. JPI
  9. Have you chech the VSV? JPI
  10. Toyota supra has the 2jz-gte and the GS300 has the 2jz-GE with VTT-i. The VTT-I engine is an interference engine, If you miss 3 teeth and the valves will bend. Non of the toyota engine has the 2jz-GE VTT-I except the lexus family. Well let me take it back the newer Toyota supra has the VVT-i, but that is in Japan. I've seen and heard many toyota techs bend the valves when changing out the belts. If you do go to the independent, make sure they are a lexus specialty shop. Otherwise Lexus dealership will be your best bet. What does it involve in the $700 repair? Do they just change out the timing belt and water pump only? I would suggest that you have the drive belt, timing belt tensioner, cam and crank seal replace at the same time. Regards, JPI
  11. We are a little far..... But kind of power are you looking? Here are a couple s/c we did in the past and present. http://i135.photobucket.com/albums/q159/jp...pg?t=1183908821 http://i135.photobucket.com/albums/q159/jp...pg?t=1183908907 http://i135.photobucket.com/albums/q159/jp...pg?t=1183908937 http://i135.photobucket.com/albums/q159/jp...pg?t=1166761505 http://i135.photobucket.com/albums/q159/jp...pg?t=1166761559 JPI
  12. We worked on many many LS. Never had one snap on us. Most of our client change them out at 90k. JP Importz

    Hey Guys!

    Hey Josh, I haven't heard from you ages. Let me know when you are back in Tejas. Regards, JPI
  14. Both steering column side by side. The 92 and 94 column does look a little bit different but they do share the same measurement and tilt motors. http://i135.photobucket.com/albums/q159/jp...pg?t=1180723567 Both ignition plugs are the same. http://i135.photobucket.com/albums/q159/jp...pg?t=1180723734 The retracting module wiring is a little bit different. All we had to do is swap them out. http://i135.photobucket.com/albums/q159/jp...pg?t=1180723797 Swapping out the ignition lock. They are quite simple to do. http://i135.photobucket.com/albums/q159/jp...pg?t=1180723906 I had to double check the lower input column shaft. They have the same measurement :woot: http://i135.photobucket.com/albums/q159/jp...pg?t=1180724148 http://i135.photobucket.com/albums/q159/jp...pg?t=1180724223 After the installation. The steering wheel steering feel much better. There aren't any feedback or resistance when making turns. Mr. Van English was very happy with the outcome and save him a lot of money. Since he is our long time client, I didn't charge the labor on this job. It's quite a learning experience though. JPI
  15. One of our good client have problem with his steering column. It makes a grinding noise when turning left and right. We had this issue in the past and a little shim was in place to fix it temporary. After modified the shim and tested the clearance on the column. The inner shaft was way out of clearance, A new steering need to be in place to fix this problem. We called lexus and they wanted $1500 just for the column ouch. BTW, This vehicle is a 94 Ls400. After a couple of sleepless night, we decided to look into swapping the donor steering column. It's a Ls400 92 with 93k miles, I wasn't sure if it's going to fit or will work. According to Lexus they have the same part number.... This part get more interesting. So I spent the entire weekend measuring all the brackets and steering column shaft. They do fit... they wiring is a little different though..... Great !!!!!! http://i135.photobucket.com/albums/q159/jp...pg?t=1180722646 http://i135.photobucket.com/albums/q159/jp...pg?t=1180723511 http://i135.photobucket.com/albums/q159/jp...pg?t=1180723543 http://i135.photobucket.com/albums/q159/jp...pg?t=1180723567 Steering column is out of the vehicle.
  16. This is with stock timing. There are a lot more of tuning left but it's pointless for to make more and the tranny will let go. JPI

Congrats to Greg again. JPI
  18. I would try to clean the IAC. If the problem doesn't go away. Check your fuel pressure and ignition. JP Importz
  19. Hey Ler, We have work on hundreds of ES300. I would suggest that you have the entire engine replaced. Depends on the condition of the donor engine but it could range from $500-$1500. Labor would be around $1500 to install. You would need to replace valve cover gaskets and all the seals. So after said and done it would be around $4000 plus. The vehicle would be down for 2-3 weeks. It wouldn't be a smart move to invest in something that is very old. As you can see the 92-93 models, have many many problems with blown headgeskets. Also it is very important that you have a written estimates from the repair shop that you are dealing with. I do understand things could happen when you are dealing with an old lexus. They need to contact you if there is any additional cost arise during the repair. Or you can ditch the vehicle, put that money toward something newer. If you are looking for something cheap, I go take look at the civic. They are cheap, reliable and easy to work on. Your date wouldn't impress if the vehicle break down on the way to your prom. Best of luck sir. JPI
  20. we took the spark plug out, black as hell and then we cleaned it and put it back in for like 30 minutes took it back out and the spark plug was black as hell again. Hello there, How is your ignition system? Are you getting sparks to the #6 cylinder? What is your fuel pressure? How about some long term fuel trim(bank 1 and 2)? What is your LT fuel at idle an 2500rpm? What is the air flow reading at idle? Have you scope the crank ? Have you hook up vaccum gauge? It's very diffiuclt to properly diagnost the vehicle without the needed information. BTW, There is no such thing as number 6 = 217 misfired. Misfired count as percentage. Sometimes it wouldn't pick up the reading on my Lexus scanner. A good ignition scope needed in these cases. JPI
  21. The computer sometimes would show the current parts number on the vehicle. It take some skills and time to keep up with the TSB. I spend about 5 hours per week to read and learn about these TSB for Lexus/Toyota and Scion. It's a very good tool to have. Regards, JPI
  22. Steve, Sorry for all the troubles that you are going through. If your current rotors are warped and you are replacing them with a newer unit. I would replace the brake pads also. We had many many issues with ES300 rotors in the past, replacing the rotors and pads at the same time would eliminate comebacks. On a second note, I'm shock that your power steering pump front seal give out this early in age. Regards, JPI
  23. There are many type of 90k Service. I would get all the details. Have them fax over the estimate before doing anything. But a typical full blown 90k service at an Independent Lexus repair shop would run $1100. JPI
  24. Hello there What year is your vehicle? How often do you service the transmission? Inspect your shifting cable. Make sure it's tight. I've seen many transmission fail due to lack of service. Good Luck. JP Importz
