Rough idle with upgrades

Post by martimus919 »

Put in revtronix chip and 550 injector, ran fine for the first minute and then started hesitating and there's a ticking noise with rough idle. It's not that powerful either, any ideas as to what's going on or any suggestions on what to try?

Um, check your intake for major leaks. I would assume you did a turbo swap and intercooler etc.

Did you change your MAF sensor by the way? Are you running stage 1 or stage 2?

I figured it out, it was the spark plug wire arcing off the head, i replaced it with one i had laying around. I've been meaning to replace them with new ones so now I'm more inclined to do so.
