Description:
The cars engine seems to hesitate like it is going to stall when
increasing speed. At traffic lights and stop signs the engine will
stall sometimes.
I have taken the car to two repair shops and a transmission shop no
one can tell me why the car is acting this way. The engine was tested
at the two shops and it is fine, computer diagnostics show nothing.
Anyone know where to look for a problem like this in a Corsica?

Thanks

Any competent shop can figure out what is wrong with it.
It may cost more than you are willing to pay, however.
Hook a laptop up to it and record driving.

If the problem occurs and goes away quick enough, then a fuel
starvation issue would not have time to set codes 44/45 (I think) for
too lean / too rich, hence no codes. Also a failing ECM board would
cause no stored codes coupled with a variety of poor running and
stalling problems. If your check engine light doe NOT come on right
after the vehicle stalls, I would suspect the ECM.

Question is ...when the car stalls does it stall losing
all power...ie PS goes as well as lights, instrumentation,
not just the engine?

I had this problem once with a Chevy Beretta and it turned
out to be a loose ground wire...the ECM was losing it's
ground. Tightening the ground relay bolt solved the prob.
