Having problems with your Chevrolet Corsica ?

I own a 93 chevy corsica, when i accelerate over 40mph, the check engine light comes on. this worries me, and it only happens when i drive over 40mph...do you know what would cause this to happen? i had to have the ecm replaced in 2007, after driving for a few months with the light coming on when i went over 40mph...and the ecm actually broke...do you think it has happened again?

Answers :

The 1st thing you need to do is find out what electronic engine control fault is causing this check engine light, also the fuel pressure could be low due to a worn fuel pump or a plugged fuel filter, has the fuel filter been replaced? to check the engine control computer for codes go to the link below for instructions on using the blink out method to read codes, also you will find a list of code definition's there..
