Previously the car had a terrible miss at low RPM under load. So, I've had the plugs, wires, both 02 sensors, idle control valve replaced....then the Optispark, ICM, and Coil replaced (twice).
Now the car is missing and running real bad once it warms up to operating temp around 200 degrees per the temp gauge.
The folks I had do the Opti also diagnosed a low voltage issue once it warmed up and replaced the alternator as well. to no avail. The car will run fine until it gets hot then stumble to the point it will shit off. If I park it somewhere while it is hot it might not crank until it cools for a few hours.
I haven't done anything with the fuel system other than an injector cleaning service.
ideas?
