This problem has been going on for the last week since new install... I got the intercooler on a few days ago hoping it was just heatsoaking the motor..


Everything is great, and after I boost around a lot, the car seems to run like ****, and spudder like mad... so I pull over and let it cool... then it seems better.

I also saw smoke coming into the cabin once i popped my hood after pulling over lastnight...

LTFT were at liek + 30 while it was spuddering like mad!


I was ripping around on the highway, then i slowed down for construction and was going about 5mph.. then the car started "hunting" for idle, and before long I had to limp it to the off ramp at 5mph and pull over, pop hood and wait about 10 minutes.

IAT = 59
ECT = 85


MAP values seemed high when nit ran like ****.. seeing 60@ 800rpm, TP 0%, 86kP at 950

my fuel trims were + 39 and MAP = 103 , 1180rpm, 21% tp

didn't see a single misfire.


once cooled, the car runs just fine...


Questions: 1 - where was the smoke coming from?
Question: 2 - What could be causing this problem only when hot
Question3 - Could the MAP sensor screw up when hot? and command more fuel?


mod: new engine, xp cam, stg3 blower , 3.0, fullsize IC etc.

Thanks for the help..

Exhaust is new, so I woudln't expect there to be any leaks yet, but will not rule that out, EGR is deleted and blocked, I will be checking again for a vac leak but it seems ok currently.


Thanks Guys.
