Anyone think this would have caused issues at idle while in gear? Also it stumbles when going wot from idle.

Any ideas? only change was plugs

Possibly. Are you running these plugs for nitrous? If so that gap is too wide.

I would pull the plugs back out and look for a cracked plug or damaged plug wire.

Is it only stumbling while spraying or also N/A?

Asking about a colder plug in the n20 section...

havent sprayed it yet so only NA data so far.

Also on cold starts, after it turns over and i try to actually get it to move theirs huge hesitation and it falls on its face for about 10 seconds or so then it smooths out and as far as i can tell np's

Update for you guys. The plugs were breaking up and causing the idle issues. Now i didnt get a chance to mess with the tune at all to see if that could remedy it. Pulling them out tomorrow and going to re gap to 30.

Will let you know how that changes things.

If you pull them and there is a gray glaze over them, chuck em in the trash. Once they get a glaze there is no saving them.
