NA Crossfire - Random miss issue
NA Crossfire - Random miss issue
I've got a 2005 NA car (6-speed) with a random miss while cruising, after the engine gets warm. Runs perfect while cold, runs fine under load at about 1/2 throttle and up. I don't really notice it above roughly 2800 rpms and up. Totally random, sometimes it's worse than other times. So far I've swapped the plugs, MAF, and throttle body. Ready to swap out the fuel pump next. No CEL codes at all. Anyone else seen this?

Re: NA Crossfire - Random miss issue
Yeah, maybe. I've replaced the crank and cam sensors with no improvement. I've had bad wires in the past, and they always seem worse when the weather is "wet" - There's no difference with this one. But, with that being said, I plan to swap the coil packs and wires from my SRT to this car and see what happens.

Re: NA Crossfire - Random miss issue
My Crossfire did the same. Later, it wouldn't start. I replaced the Relay Control Module with one made by Standard (about $120), which solved the problem and made the car perform much better. No code was thrown. More recently, the Crankshaft Position Sensor failed. I replaced it, and the code was eliminated. The car runs even better now. Maybe it's time to replace the camshaft position sensor just for grins.
