maxed_out

Hey how did this turn out????

Hey good luck. I did mine a couple years ago and it needed to be flushed too. I had to put in new oil compatible with 134a,new o rings, and a different drier (also compatible with 134a) . I read about the procedure online for a few days before and If I had the link I would have posted it for yah. You might want to try a search for the specific procedure before jumping. I also took the compressor out and had an a/c shop go over it. They fixed a leak by rebuilding it. Found the leak because of all the oil drooling off compressor. All turned out well...I'm no a/c pro but I'm pretty happy with the results...been a couple years and no problems and if I need a can I can of juice I can find one pretty easily. I've since heard stories about folks doing a lot less than I went through and they swear by there results. I also learned on this forum that you can get r12 on ebay. I had no idea. Let us know how it goes!

If someone has a procedure to rebuild one I'd love to see it. I had heard that Lexus had a kit available at one time but when my dealer "checked" it was no longer available. Anybody got access to TSB's or equivilant and could do a search would be great.

Econ.... we are on the same page. I would say that the 134 does not cool as well but you really can't notice it. Some days its gets really cold and I have to turn the ac off. As I recall I had to replace the drier and clean out the old oil from the system. I recharged with the proper type and amount of oil and 134....and have not had any troubles over 3yrs. Oh yeah I think I had to change O rings too. I dont remember where I got the procedure to convert but it was on the internet somewhere and straight forward. Hope this helps somebody.

I didnt think you can get R12 anymore in a can? Its been outlawed because of the supposed hole it has created in the ozone layer. I converted my 91LS over to 134. A bit of a project but it can be done. The nice thing is that the 134 is only 5 bucks a can at Walmart.

lee, hey dont feel so bad. Have to agree with nc211. Go for throttle position sensor. Mine did something similiar and it was the tps. Maybe all you need is to have it adjusted?????

Dry fly, Thats a new one for me. Thanks for posting. How did you find it?

Man at this point it could be anything. Theres a couple other threads like this. Make sure your alt is charging. Weak battery and no charge can do this. If thats ok make sure your igition is ok, plugs, wires, caps etc. Do you have spark on all 8 cylinders? Broken of frayed wire? Pinched? If thats ok consider something on the fuel side, fuel pump, fuel pressure, throttle posion sensor etc. Check some of this and post details.

dont know if it helps but there is at least one active thread on same subject. he went after ingition system issues. good luck

Hey sorry about that...the pcv was just a get it done type thing. My buddy says it could be related but I have to agree its probably not. on this one, go for ignition related issue. What about an update on whats new if anything? Did you cook one cat?

hey 914lps. If it was me and time was short, I'd use seafoam. Use the Spray can to do the TB-like the day before. hey if you got no time I understand.... Theres nothing like cleaning the tb with it off. Use the seafoam liquid before you go.... Get down to about a 1/4 tank o gas and add 1/2 can of seafoam to gas tank. Add the other half to the crankcase. Drive. See if you notice anything like I did. Theres pretty good directions on-line for the seafoam. There's a couple variations on applications. My 91 lex never ran better. My 90 Camry with 270k is doing 32 mpg because of the stuff.

914lps, Seafaom is an engine additive. Also sold as "deep creep" in a spray can. http://www.seafoamsales.com/products.htm I dont work them, just read about it, lots of folks pretty pleased and I tried it and was amazed. Picked it up at Autozone for 5 a can.

hey davidk how this turn out? update?

Red cats=unburned fuel. Not good usually. 1. Change your plugs and make sure they are all sparking properly. Use platinum dont buy crap plugs. 2.Check your air intake. Clean or replace pcv. 3. Let us know how number one turns out.

My dealer told me that there once was a kit to DIY your own rebuild on the struts. Anybody verify or comment? I have a spare strut with i'm thinking about sacrificing.

Agree fuel pressure possible. Could be cold start injector :whistles: Whens the last time you cleaned the injectors? I started using seafoam which works well.

have to agree with VGR. lets make sure you are making electricty,plus charging and a good battery before we talk fuel. Please let us know as it unfolds.

I always wonder if someone bought Microsoft stock instead of spending on LS 400 in 1991 what would it be worth? I didnt buy the 91 then (its used) but I have the orig sticker and its shocking because it had every option and came in around $60k. The costs for the Nakamichi and Air Susp blow your mind. Anybody know how much that 60K in 1991 in Microssoft is worth in Microsoft today? :whistles:

Just bumping. With over 700 active readers we have to do better than 30 replies. C'mon what do the rest of you got? Just bought a 1995 SR5 with 105K and from all I read the 22re thats inside is good for 500k. Maxed

Hey folks its my turn to do the ACV on the power steering pump. Where do I want to buy? Dealer is at $76. Thanks in advance.

Where the challenge in that? How about burning the money! The point here is educating ourselves so you dont have to always run to dealer. I like my dealer but he doesnt get to see every sniffle.

almost forgot, my 90 camry just rolled through 270,000. Change the oil every 3,000.

davidk, You have to start eliminating possibilites. We'll try to help you. Replacing plugs and wires is good first one. Use the good stuff. Fuel is another possibility: Fuel filter, fuel pressure etc. Note, I have seen water in the tank do exactly the same as you describe. Water is becoming a big problem caused by ethanol in fuels because in sucks water out the air. It ususally can mix with the fuel but sometimes over time you get too much and water sits in the bottom of the tank. Slower speeds means the mass can go accross the fuel pick and it gets sucked in. Is your tank properly vented via the gas cap? The gas cap can be checked at a shop. Again a problem here can caused whats called pressure lock under certain conditions. Start eliminating stuff and we'll help you through.

these posts are great. what great cars.

Just thought we'd have some fun. Blake918 has 250k on his car. Congrats.... I have 112k my 91LS-kinda feel like a rookie. What do the rest of you have? :whistles:
