he didn't say when he hits low rpms
he said he's cruising and from the way he said it it sounds like it's spontaneous

 

maybe a clogged injector or a bum spark plug... **** man it could be a million things. thats my best guesses

 

i have a fuel gauge it says rich but it bounces aroound. i had greddy send me the base map for the car. runs alittle better but still bucks. thinking i have either a bad axle or bad motor mounts. but as i down shift it buxs so im thinking clutch or axles. ill keep updated.

 

have you changed the plugs lately? i think .32 is the gap yu want for boost.

is teh a/f gauge wideband or just a leanband? Don't trust it if its lean! Don't use that as evidence for a problem at all, its not accurate in the least bit.

My car sometimes did that before i was boosted though. I'd say check spark plugs, get the basemap TUNED, check PCV/IACV (i would just disable the IACV altogether if you can with the Emanage), and maybe some seafoam.

 

im running 7 pounds of boosty right now, so would i still gap the plugs at .32? the a/f gauge is one from autozone. but it does bounce around. the engine was completely rebuilt so i dont think i would need the seafoam.
