Engine Performance problem
1988 Pontiac Firebird V8 Two Wheel Drive Automatic 57500 miles
I am French an I own a 1988 Pontiac Trans Am V8 5.0L 305 TPI with an automatic transmission.
I have a big problem with the engine :
The ESC code default comes intermittently and when the "engine soon" light turn on, the car doesn't not have any more power.
I have changed the distributor rotor, the park plugs, spark plug wires, the coil and the ESC (Electronic Spark Control module) and the knock sensor.
But I still have the same problem.
When I start the engine car cold, the engine turn nice, but when I accelerate gently, it's like if the engine suffocate.
When the engine is hot and when I kick down, the "engine soon" light turn on, sometimes, and the car loose power. It's like I drive an asthmatic car. So I turn off the engine and restart many seconds after, the trouble light is off and the engine find power again.
Do you have an idea? This trouble makes me crasy.
have the same problem?
