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.

Do you think they're running lean? Rich? After checking sites, they look like normal wear and tear to me. Maybe too hot?

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.

How many miles on those plugs?
