I have a b18b boosted running uberdata. Yes I know Uberdata ?'s are for that site but this is something else I think. I had my car dialed in damn near perfect, maybe a lil rich in vaccum. Then all of the sudden it started cutting out on me so I datalogged and it seemed ok. I went ahead and cleaned up the tune a lil from my winter tune on it though "3 months ago." I checked the plugs and there fine, looked over my wiring that checked out good. I have full MSD setup for ignition which is 2 years old. The problem is when I rev it up it's got some miss to it. And when I take off normal driving it cuts out all through vaccum. Once I get in boost it clears up alot but still has a couple spots. I searched ignition problems and couldn't get anything cept changing my boost retard on uberdata from .07 to .05. If anyone had a similar problem and fixed it please let me know. Sorry for the possible confusion ^ and long post.

 

I very much doubt your plugs are fine.

No that's what I read in some topic that I researched. I have my boost retard at .07 or .7 whatever it is, as recomended. And I checked my plugs which were good. Hell I even replaced them just to be sure and gapped them.

BUT, I just got back from taking the car out and trying to figure it out again for the billionth time and it ran great??? I'm not sure what happened but my a/f ratio is 12.4 and it runs great. It's not cutting out anymore or anything. I wish I new if there was a "real" problem so it can be fixed. I hate when **** fixes itself on it's own, it leaves ya puzzled. Well thanks anyways but for now it's fixed I guess

 

pull out all that MSD crap and run the stock ignition with a new set of plugs......
