Hey guys,
New issue appeared yesterday. Car has a rough idle, tac is bouncing 50-100 rpm and when I take my foot off the brake when it's in gear it pushes the car forward makes the whole car kind of bounce forward. Boost seems ok, when the rpms are higher, it doesn't happen, has full power when I floor it. What could be the issue?

Maybe a vacuum leak, any codes? Are you running torque?
Did you try a new/different gas station lately.

Hopefully not a torque converter.  How have the temps been since the cooler installation?

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

No codes. Only thing I have noticed in torque is the trims are pulling fuel . Ltft is -9 and it has always been +9 when running well. TC is probably fine, runs very uneven in neutral or park. Also runs crappy on low rpm even at 40. I'm leaning towards a bad coil pack. I can hear the turbo is also affected because you can hear the choppiness in the turbo whine so it has to be before the turbo. No codes. Trans temps are never higher than coolant temp, usually 160-170.

If LTFT is showing running rich, you may have an injector problem, any smell of gas at any time?  I'd try cleaning the MAP sensors also.

Which version of the tune are you running, and how many miles on the plugs?

Plugs have about 15k , I just checked them and they look ok. Lms v10 and I just installed ppe catted DPS . Haven't smelled gas. Put 87 tune in and it's the same. I assume that the lms tune already accounts for DPS.

From what I remember, LME does assume Downpipes are installed and they turn off the rear O2's.  Can you see what the tune is specifically called?  There used to be acronyms after the version number that would tell you if the tune accounts for Tstat, or DPs, etc.

I only see 93 performance v10 3 bar.  So looks like downpipes are NOT accounted for (or they ran out of room in the naming convention).  Def worth a call to LME.

I don't think that will be the case.  Like I said, they probably just changed the naming convention.

I think so too because from my email chains from LMS, anything 2 bar is for stock dps and 3 bar tunes are all bolt-ons.

I put them in a week and a half ago. Was running great until last night. I tanked up and when I started the car, it started jerking at idle when I took my foot off the brake. I wouldn't think bad gas would affect the car that quickly.

The only problem I can her is an exhaust leak most likely off the turbo to downpipe connection.
