Started after 60# injectors and PCM tune and dual pass. What could it be? I thought maybe running to rich at idle

 

9 times out of 10 its ur maf sensor so start there.... do u have a canned tune or hp tuners????

 

can tune

 

Canned tune? What's that mean? I sent my PCM to zzp

 

Canned tune means the tuner wasn't there in ur car doin it.... but zzp is usually pritty good with there tunes.... are u throwing a cel???

 

Is your throttle body clean?

(Fwiw, I have the same set-up with the same tune and have cleaned my throttle body/maf and have a stock intake and get idle bounce. A custom tune should eliminate it).

What does rough idle mean? Surging? Misfires?

Find someone with HPT to figure out how it is fueling and how the tune looks.

Still a canned tune, they didnt do any logs for the tune, so its not the best.

 

A lot of times with canned tunes they don't factor in elevation ( messes with air density) so they will be a off... a canned tune for the most part is put in place so u can drive the car to a tuner to get dialed in.... if u don't have one u should get a afr gauge before u go to get tuned....

 

first off do you have a wideband, if not take your car and throw it off a cliff, if you do great job bro. start here, look inside your engine bay for a vacumm leak. If none, go to the maf;/ air filter clean both. check throttle body. Make sure the tune on your car is correct, call tim up at zzp and ask him the same question your asking us. i do not like canned tunes, and i hope you can afford a real tune soon.

good luck

 

If you dont have a wide band get one it will help when you get a real tune.

 

Thanks for chimein in james....lol by the way I wonna set somthin up for this spring for u to tune me for 60's , 2.8 and some cooling mods.... I think I have a few guys that are gonna make the ride with me for ur special services... wink wink...

It's the 60# injectors.

Its tough to get them to idle nice with a canned tune.
