About two months ago my H3 had been giving me the STAB SYSTEM failure alert before pretty much going into limp mode. The engine sounds awful when idle and I checked everything for corrosion and replaced the throttle pedal itself and I still have this problem. Anyone have any advice?

I5 Tactical Edition with 95k, I was planning on theAirDoc Intake since it was made specifically for hummers (basically) and a quick throttle tune for some kick. Even a straight pipe. Anyone else find any better success? Would love to keep it about 650 or less this summer!
