Hi , just bought a 1997 red GTP supercharged. 160000 miles, no mods yet.
Fixing things previous owner neglected : fuel filter changed, cleaned MAF and IAC. Changed air filter back to regular Fram, K & N was in there. ( will probably go back to that eventually ). P0171 code pops up and P0441 rarely.
Will check more for vacuum leaks and purge valve. Forum looks to be good source of info, thanks![]()
