Cylinder 4 Misfire - New coils / plugs / fuel injector
hello -
I am trying to figure this misfire out... bought the car 2 days ago and drove fine and we pushed it hard during test drive. Drove fine for 10 hours straight then when we downshifted, it triggered a misfire and Drive Train malfunction. I replaced all 8 spark plugs and ignition coils with oem BOSCH and replaced 1 fuel injector on cylinder 4. Cylinder 4 seems to constantly misfire as soon as the engine starts you can hear it. (Combustion misfire code) Compression test is the only thing i havnt done yet... any ideas here or am i F**KED after just buying the car |

Compression test came out okay all 1-4 cylinders are 170-180 in compresssion
We did code the new injector We are doing injector actuation test and turning off cylinders 1,3,4 all cause they engine to stumble but 2 doesn't do anything so I wonder if it's something |
