stuttering at WOT

1138 Views 6 Replies 3 Participants Last post by  Monkey Boy
Hey guys, I've had a couple instances of the car stuttering and stammering at WOT. It happens at low and high RPMs and most of the time within a second or so of going to WOT. I just put the JLT on the car a couple weeks ago and haven't had a chance to get it tuned. This is the only problem I've got, no rough idle, no stalling or anything like that. I need some help folks.

Think it made it richer?? If anything I would think it leaned it out some. I put in just a touch more fuel with the predator this morning before heading to work. It didn't do it at all since I made that change. I'll keep an eye on it. If it continues I'll probably pull some timing out just to be safe until I can get it tuned.

I haven't had a screen on this one since I bought it and put the CAI on there. What's the deal with the MAF position? The JLT places it inside the fenderwell with the filter which makes repositioning the MAF a little tedious because of the wire length. I think I can rotate it some, I'll have to crawl in there and get a good look first.

Oh yeah, I haven't had anymore instances of the stuttering since I put some fuel in the tune. I'll do the MAF thing anyway if possible, just to make sure. I've got some time off over the holidays so I should be able to get a little time on a dyno to check the A/F ratio and get some new numbers for comparison.
