Well, your cold (open loop) start up is EXTREMELY lean!!!!! Both o f mine for example hover around in the 700's during cold startup/open loop.
Once in closed loop I see your idle BLM's climb to 150. You have a vacuum leak?? or a pre turbo exhaust leak??

Ok. what should i do to fix it? Which code is it that i have to look at? The one you are talking about. Sorry, but i am new to this. It doesnt seem like i have an exhaust or vacuum leak.
The INT & BL is what's indicating a VERY lean condition.
The INT is short term fueling ( like almost real time fueling ) & the BL is long term fueling ( over the course of minutres/hours of driving )
Anything above 128 ( 128 is baseline or neutral ) the ECU is adding fuel to compensate for lean, anything below 128 the ECU is subtracting fuel for a rich condition.
At a hot idle I'd spray aerosol NON-Flamable Brake-Kleen all over the vacuum lines, throttle body, vacuum block, EGR, intake, basically all over the engine to fine a vacuum leak.
I had the vacuum line going to the fuel pressure regulator pop off at the strip one time (thank God for Alcohol injection) and my INT pegged at 150 trying to richen the mix. I'd look at that line first.

It's running lean...and likely the reason it's stuttering. Check for vacuum/exhaust leaks. If you haven't got a TT chip...then I suggest you order one from Eric.
Sorry, but who is eric?
How do i bring it up? The throttle body? Anybody have a link to how to adjust it? Would the tps also need to be reset/adjusted?
This page should help you out

Very good info, thank you!
Total JUNK!! Get a TurboTweak chip & supporting mods if you don't already have them (adjustable FPR & Hotwire kit)
The chip might be partly to blame, but not all. For your INT & BL to be maxing out trying to compensate for a lean condition, there's something else wrong besides a $hitty chip. Again, you either have a vacuum leak, weak fuel pump, clogged fuel filter... something.
I'm not trying to be an ass when I say this, but you sound as though you have zero clue about these cars. Maybe a board member who knows WTF he/she is doing lives near you & can help hands-on vs just on here.
Post up a help thread maybe looking for hands-on help with the car. In the mean time, read read read here. Lots of great info about anything bumper to bumper.
Lmao, you are right, i am new to these cars and have no clue. Thanks for the input!
