Hi I have a major problem that is stumping me.I have a 1994 Toyota Camry that runs fine for a while then starts to miss when it gets hot(not overheated but not just warm) . I have checked the IAC valve at all temps the Air Temp sensor EGR temp sensor etc. All check out fine. Changed the dist. cap and rotor, plugs, and wires. When I start the car it runs fine until it heats up ad then it starts to miss violently. I thought I had it fixed today when I cleaned the EGR Temp Sensor it ran great for a while then after a lenghty test drive(10-15 miles) it started again. Really starts missing when anything electrical is turnd on but I checked he alternator and battey and both are fine as well.

Sounds like it could be an injector problem. Is the check engine light on? runs smooth when cold? If you have a meter, warm the car up and measure the resistance across each injector to see if any one is out of range, need to do this when the problem is occuring, shut car off and test

I have the same problem with my 95, and my friend with his 96. I have replaced the plugs, wires, cap, rotor, and coil, no luck. I have cleaned the injectors manually, and put injector cleaner in the tank, no luck. Someone must have run across this before, I think it seems to be a problem with the 94 - 96s. I have worked on cars for years and I am stumped on this one, and unfortunatley the diagnostics are horrible. I do miss that about gm cars.
