Rough Idle, Lumpy on throttle load
MSM decided to not work today. Drove fine last night.
Car has a rough idle. When I rev it up to about 2k rpms in park it'll hold but stumble and drop rpm randomly. When I drive around in 1st gear it seems fine until I give it more throttle then it stumbles. Under any heavy load it'll stumble and sound like a subaru. Not sure if it's running rich or lean, injectors or ignition. Halp. Side note, I did fill up with gas yesterday before coming home... possible I got some bad gas? |

Pull and inspect plugs. If nothing conclusive pull wires off one at a time and see which cylinder makes the least difference.

Alrighty, so either an injector is stuck open or the coil is not firing. Running rich.
Pulled a p0302 for cylinder 2 misfire. I won't be able to inspect plugs until later. I'm going to swap the coil packs and see if I can get it to misfire on another cylinder. |
