Hey guys. New to the site and to Stangs. I had a 07 Crown Vic P71, which is similar drivetrain wise so I am somewhat familiar with them.
I got this Mustang this last weekend. There was no CEL or anything. I heard a small misfire/stumble when I was checking the car out but didn't think too much about it. Car still goes down the road smooth and seems to have plenty of power/acceleration. It only seems to stumble at idle. I checked out the #2 cylinder and he had a no brand COP on it. I swapped that out with a new OEM and changed all the spark plugs. Once I did that the car seemed to idle a lot better..but not perfect.
Cleared the code and drove it a couple days without the code. Stopped to pick my daughter up today and as I was waiting I felt the car idle a little different. Still no CEL but I checked my codes and sure enough I get the P0302 again.
I did notice when I did the coil that there is a injector that's different then the rest. It isn't OEM, pink in color and it has a different non OEM harness spliced in. It still looks like a EV1 connector just a different style of locking device. I think I will try swapping this out and finding a stock harness and a wrecking yard to splice back in to the harness.
Is there anything else I could check as I am troubleshooting this? I didnt notice any vacuum leaks anywhere, but don't know where actually to look that could cause this.
Thanks for any info given in advance .
