I've been troubleshooting this for a few weeks now to no avail.
-P0302 OBD code after clearing and driving for 5-30 miles. 205k miles.
-Car runs rough at idle, moreso in gear. Removing individual coil wires seems to cause car to run worse for all 4.
-Swapped around coils and cleared OBD, P0302 (cyl 2 misfire) returns
-Replaced all plugs, no change
-Had a mechanic take a look and he concluded the 2nd injector was likely at fault, so he replaced. P0302 returned the next day. This was after confirming spark and compression test revealed no major issues.
-Only thing changed withing the last 6mo was replacement of the CHT sensor as it was faulting which fixed the issue (no temp reading, CEL).
Any ideas? All I can think of now is the injector/coil wire/connector is bad on the second cylinder or there's another random issue causing the fault erroneously. Thanks in advance!
