Re: Need Engine help PLZ
Yeah, I'm with novaderrik. I think it's an ignition issue. Here's an easy way to check:
Start the engine and rev it up (you may need a buddy in the car), get it revving until you notice the skipping. Now, as it's skipping (shuddering) pull off one plug wire at a time. They make a special tool to do this so you can avoid getting shocked. Alternatively, you can use the sharp end of a test light and pierce the shock boot to short out the wire.
What you're looking for is: difference (or no difference) in engine sound as you disconnect (or short) the plug wire. If you disconnect a plug wire and the engine is running much rougher, then you know that cylinder is working. If you disconnect a plug wire and there is NO difference in engine sound, then that cylinder is NOT working.
If you find a cylinder that's not working, take off the plug wire, insert an old spark plug into the boot and lay the plug against the engine metal, then start engine and see if you have spark.
This will give you an idea of where to start looking for the problem.
