That stupid misfire problem is acting up again. Sometimes, on startup, the car will start to miss and then set a code. The code is always P0301 - Cyl 1 Misfire. I have changed all plugs and the wire set. I don't think it's the coil cause it's not affecting the companion cylinder. I've tried swithching wires and plugs around to see if it moves, but it does not. Could it posssibly be a clogged or malfunctioning injector? I'm at my wits end with this thing. :angry: Any assistance would be greatly appreciated.

Run a compression test on the whole engine; does #1 cylinder read lower than the rest? If so, problem is mechanical. If not, check the coil pack. Could also be fuel injector, if compression ok. That will get you started, at least.
