Problem with 1998 Camaro 3.8 V6 (Misfire)
hi,
hope some one can maybe give me a hint to solve my problem.
the camaro started misfiring and also has the trouble code p0300 and p0300 p
i already exchanged the spark plugs. everything else is almost untouched...just checked for leaks and made sure no wiring is damaged.
after letting it run for a few minutes in idle it always starts smelling like rotten eggs... maybve someone knows this problem?
i am not sure what to exchange next as i am located in germany and even some spark wires cost like almost 200$...
if an ignition modul was damaged would it throw out a trouble code?
thanks to anyone that can help

Welcome to our forums
There are a lot of things that can cause a motor to misfire. Without the proper equipment it is tuff to determine what it is. You need a Scope. The miss can be caused by Plugs, wires , coils, ignition module, a blown head gasket, a leaking injector and maybe a few more things I am forgetting.
In the normal life of a car your plug wires are good for about 6 years. Most people do not exchange them and just keep driving the car. As they age the buildup resistance. The resistance will get so high that it will cause the coil to spike up to 60,000 volts just to fire a plug at idle. The car feels fine at this point but the coil is overheating. The extra heat and draw from the coil can damage the ignition module. If your plug wires are more than 6 years old, replace them then move the coil to another location on the module and see if the miss comes back. If it does check the code and see if it followed the coil or stayed at the same cylinder. You could try to swap the coils now and see if the miss follows the coil but you might be damage a second coil in the process.
It is normal for the spark plug wires to fix the problem then in a week or two the miss comes back because the coil finally fails. This drives people crazy because they think the problem was the coil the whole time.
