Josh was looking for a car but when I saw this going for a good price, my family convinced me to jump on it and give Josh the Golf GTI. It has 250,000 Kms but the seller rust proofed the underside for me and it came with new brakes all round and all season tires.
When I punched it to overtake someone the other day, I started getting some hesitation and then the CEL started flashing indicating that there had been some misfires. I pulled the pending code that indicated the misfire was on cylinder 4 only so I figured the first place to start was spark plugs. CarQuest was able to get me some at a very reasonable price so I ordered 4 and installed them, also swapped coils on cylinders 1 and 4 just in case. The plug in cylinder 4 was the worst and was well worn, wouldn’t be surprised if it was original!
