Seeking some help concerning a P2229 code for my 2005 Pontiac Grand Prix GTP 3.8L V6 Supercharged. I have replaced the MAP sensors(there are 2) after rebuilding the supercharger, reworked my vacuum lines, replaced the boost bypass solenoid. Haven't been able to get rid of this code and it keeps coming back causing the vehicle to go into what I believe is "Limp Mode" when a message pops up saying "Reduced Engine Power." Additional the message display always say "Service Stability Control/ Service Traction Control." If I don't have to replace the Catalytic Converter then I'm not trying to...yet. Please advise...it's starting to work my nerves.
