I was running on the highway and after the run, my car started studdering badly. I limped it to a gas station and filled up and checked oil. Added a 1/4 quart. When doing the run, I was low on gas. After the fill up, car stopped most of the studdering but I was worried to rev it. I could feel I was down on power. While they're out, I'll do another compression test. Last one I did 3 months ago were 235-238 all across the board.
Checking my plugs today they seem ok... Should I replace them though?
Mods are HKS Intake, Comptech header, Berk HFC, HKS exhaust.
Well, I just replaced the plugs as they were at 60k miles and I had the planned to replace them before I get tuned next week. It was already ordered and came in today.
As I was looking over the engine bay, I saw the map sensor was a bit off. Adjusted that as well and everything seems fine now!
Now I'll never know what it could've been... I'm leaning more towards the MAP.
