Hey everyone,
Yesterday I bought my first W body and 4th Pontiac, a 2002 GTP coupe. I recently sold an 85 Fiero GT and still have my 91 TA and a 2006 G6 Coupe. The GTP has 80k miles, very clean, with the following mods:
2.9 Pulley
Polished Gen V Supercharger
N* Throttle Body
ZZP full size intercooler
TOG Ceramic coated headers
Full Custom Exhaust
GXP brakes
Full Dyno tune
I just wanted to introduce myself, as well as present a problem that came with the car:
The idle is somewhat rough. Never enough to stall, but it surges after warmup. I was told it was normal and done after the tune, but I wanted to get your opinions as well. From what I've noticed so far, it's had no impact on drive ability, but it is still a concern I have. Was told there is no vacuum leak.
