  1. I put a new ECU on and it dos not smoke. The timing keeps moving. It did this before the ECU too. Now the timing seems to be off I will set it, rotate the engine and it is good then I start car up and run it. Then I check all the marks on the cams and crank and they are off again. It is a new belt could it be the tensioner? Thanks again
  2. No I put new haed gaskets on it. I also put new computer.
  3. My car has a rough idle and it hesitates when accelerating. Once you get going it runs like a champ. It also kinda bucks when driving sometimes. Does anybody have any suggestions? Thanks Alot
  4. Thanks evrybody I am putting a new ecu om tomorrow hopefully this will correct the problem. Ill let you know.
  5. Can you just put in a different ECM from one car to anthor? Someone said something about flashing or something. What is that? Thanks
  6. My car has been doing the same thing. 93 ES300. I have changed everything including the head gaskets. Will the ECM really fix this problem? I am ready to get rid of it. But if this will fix it i will try it. Thanks
  7. Now it does not smoke all the time. It just idles rough and no acceleration. It will eventually go it just takes awhile.
  8. no its not losing coolant. I have no engine codes. The smoke smells like gas, It is kinda blueish white. The oil and coolant is not mixing. I have been working on this thing for months and can not figure it out. Could it be the injectors? Thanks for the help
  9. I just put new head gaskets on my 93 es300 and it smokes so bad. The smoke just rolls out. It smells like gas and the heater doesnt work. I put all new gaskets, Thermostat and cleaned everything good. I am lost I thought for sure the head gaskets would fix this problem. It was doing the same thing before I put on the gaskets. It also idles funny but that is probally because it is burning to much gas. I read somewhere something about the power steering fluid going into the intake and burning. If anybody can help i would really appreciate it.
  10. Just found out that it is the head gasket so I will be changing this out in the next couple of weeks. Thanks for the help The PCV valve located on the valve cover may be clogged. This valve allows the gases that escape into the crankcase to be recirculated into the engine thro the intake manifold. A clogged PCV valve causes rough idle, high fuel consumption and sludge formation. This valve and mounting grommet would have become brittle with age and will break and fall into the valve cover when removed. Tweezers are required to remove the broken pieces. Napa stocks both the valve and grommet. The fuel filter becomes clogged, causing poor fuel delivery and poor acceleration. The fuel filter in the older Lexus' use a flare nut at the inlet end. I just stripped the nut today trying to take it off with an open ended wrench. A special wrench called a flare nut wrench is required to open the fuel filter nut. The torque required to open this nut is very high and only a power tool can unlock the nut. You will need to take it to a mechanic. Ask the mechanic to oil the threads before installing the new filter. Use a good brand complete fuel system cleaner for high mileage engines to clean the fuel injectors, valves, and combustion chamber. Good luck - let me know how this goes!!
  11. I have a 93 es300 and it started idleing rough and has poor acceleration. I have replaced plugs, wire rotor , cap. Have also put IACV and new coil. new tps. Have also took catylatic converter off and it checks good. It still runs rough and acts like it does not want to shift. It smells like gas coming from the exhaust. When you first start it it runs ok on first of the day start. As it warms up it gets even worse. PLEASE SOMEBODY HELP ME.
  12. it reads about 200psi the book says it shouls be close to 218.
  13. Now that i look at the gauge it does start out on about 45. sorry about that. Someone told me to check the idle air control valve. Does anybody know anything about that. Thanks
  14. My 93 es300 has been burning alot of gas. It started running rough sometimes and burning alot of gas. It also smokes sometimes not all the time. sometimes the smoke smells like anti freeze sometimes I think it smells like gas. It burns so much gas that you can smell it while it is running. Yesterday it overheated on me. It does not have water in the oil. There are no anti freeze leaks anywhere. I put new plugs and wires. I also checked compression and they all have about 235 psi. The check engine light is not on. Someone told me they thought it was head gasket but compression checked out ok. Every once in awhile it will run just fine. I am lost if anybody can figure this thing out I would appriciate it. Ill try anything for it was a good car. Thanks
  15. Could it be a bad head gasket even though it does not have water in the oil? thanks
  16. I have checked a few things out. The check engine light does not come on. there is no water in the oil. It did overheat today and i dont know why. It still runs rough. I changed plugs and wires. Seemed to help but then it started rite back. Could it be distrubtor cap or the transmission? What about the fuel filter ? I need help for I have no money to take it to a dealer. Thanks again
  17. I dont seem to see gas leaking anywhere. I smell it inside and out. You can really smell it through the exhaust. The exhaust is smoking bad. I believe it is running rich because it is really sucking down the gas. It does not do it all the time but it does do it most of the time. it does not idle very good either when its running rich.What causes it to run rich? Thanks again
  18. someone told me it could be the catylitic converter. Does anyone know if this is true
  19. someone told me it could be the catylitic converter. Does anyone know if this is true
  20. I have a 93 ES300 and it smells like gas really bad. It also has smoke coming out of the exhaust. The idle has gotten really bad too. The gas mileage has gotten really bad. It smells rich. It does not have water in the oil I checked that out. Please help me out cant seem to figure this thing out.

  22. Hey I just got the car running and it runs great. It was a bad maf and the shop had the timing belt put on wrong. Just fixed it all myself. Bought the car for 1000 and the kid did not know what was wrong with it. He paid 1300 to have new water pump,radiator, timing belt and some misc. done.Put 60.00 into it and now have a nice car. Thanks everybody for the help.
  23. So your saying the maf needs to be plugged in and i must have anthor problem other than that?
