[QUOTE="bobcat, post: 1588720, member: 29868"] Give me a old school engine with a distributor and carb and I'm off the chain but this is a different beast. I've read how dependable these 4.6 4v engines are the way it revs after it gets past the misfire makes me believe it's something simple. I will add that it also has another issue that may or may not be related. The car will drain the battery if I leave the battery connected and it sits idle for a couple days. Nothing is on or running when the key is off. I've removed fuses in an attempt to locate a dead short but haven't found anything. After doing some research I found that some folks had a problem with the amps on their Mach 460 systems not "going to sleep" when the key is off. I can't find a fuse dedicated to the amps to remove.
