1996 camaro 3.8 miss firing what do you do?

Answer 1

usually when these motors misfire you have a few possibilities. First take a timing light and check each wire close to the coil remember these are dual firing meaning they fire both time the cylinder hits tdc both on the compression and exhaust stroke. if you find one that looks like it is missing every now and then replace that coil. usually the coil is the problem but if you replaced the offending coil and it is still doing the same thing verify with the timing light that it is still same coil then there is a problem in either the base the coil plugs into or the wiring running from the ecu to that base. there is also one other possibility and that is the crank sensor that tells the ecu when to fire the plugs this is usually the cheapest part to replace but only go to this if it looks like all 3 coil packs are missing. good luck on this problem it can be time consuming to figure out
