Dear JK: we have this cavalier at the shop and it dies when
u turn on the wipers charging sys ok im thinking ignition switch
problems i will check it out wed to find out was wondering if u heard of
this thing thanx in advance.
JK:
Yea, ignition switch sounds promising.
I would also check something if you have not come across this before.
The harness connector under the carpet by your left foot. It is prone to
burning.
Usually the fuel pump circuit, or the rear defogger. The wipers may draw
enough away from the fuel pump to cause this problem.

Answer: Usually a misfire will set the Check Engine light on with a trouble code. The raw gas
smell could be a leaking fuel pressure regulator. When they leak, they leak gas into its vacuum
line causing a very rich condition, and misfires. The plugs and/or coil may have not been
replaced properly, or not replaced with genuine GM parts. You could possibly have a bad
ignition module or the coil housing is shorted internally. This is the large black plastic housing
that the could sit it. It distributes spark to the plug boots, then to the plugs. Even the timing
being off will cause the issue you describe. Since you have multiple misfires, it is probably not a
fuel injector problem, although bad gas will create a rough running problem. Fuel pressure
should also be checked, and possibly replace the fuel filter if plugged. There are a lot of
possibilities, but I would start first by checking the fuel pressure regulator.
