I have a 1989 Toyota Camry LE V6 with 96,000 miles. It is an automatic. I left it sitting for approximately 2 weeks and when I went to drive it, it wouldn't accelerate over about 15 mph, the idle was low and rough, and I had to have it towed. The mechanic couldn't replicate the acceleration problem, but replaced the battery, coolant temp sensor, spark plugs, distributor rotor, and fuel filter to treat the low, rough idle. Still, the idle was low and rough and they couldn't do any more to fix it and asked me to come pick it up.
Since then, I've been to two other mechanics, including a dealership, and had the following:
throttle body cleaned
mass air flow sensor replaced
EGR valve replace
EGR vacuum modulator replaced,
cold start injector replaced.
Still the car idles low at times and will stall out at hard stops. If I stop gently, the RPM's may decrease but probably won't stall. It accelerates okay, but seems to lack a little power. The idle air control valve clicks after I turn the engine off, which is apparently a sign that it is working correctly. What else should I be looking at? Ignition Coil? Fuel Pressure regulator? Alternator? ECU? I can't afford to keep throwing good money after bad to fix this... please help.
