son in law has a 93. It started a problem of running rough. It got worse and
he had a tune up done complete changing plugs and wires. Did not help. Now
with driving and you put a window down the motor will shut off. Problem is
the computer chip. We have been told this is a command problem. We tried to
find one at a junk yard but they are hard to come by and very costly. You
must get a chip that match's your car.
Exactly how is this making the car run rough, misfire, runs rich anyone scan
it for the problem? Napa has exchange ecms, used is no good, but I don't
think this is your problem, info is too thin to really comment.
Its son in laws so I don't really know what all he has done. All I know he
was told its the chip and was told by another owner they had the same
problem. We could not find any at NAPA they said its dealer only or used
part but it must match the car.
