AFTER CAR WARMS UP, AT 3/4 THROTTLE, OR SOME TIMES JUST SHIFTING, I LOOSE BOOST AND IT GOES INTO REDUCED POWER. REPLACED THE MAF, MAP, AND BOOST SENSORS. TOOK OFF THE THROTTLE BODY AND IT WAS CLEAN, DID A RELEARN AND IT RAN FINE UNTIL IT WAS WARMED UP AND AT FULL THROTTLE. HAS A 8 MONTH OLD NEW PEDAL AND THE THROTTLE BODY IS ONLY 10 MONTHS OLD. I GET AN OBII SCAN CODE, PO94, OVERBOOST AND A PO11 CODE.
IT HAS MAX CARE FROM CARMAX. ALL I DID WAS PUT A COLD AIR INTAKE FILTER AND MAGNAFLOW EXAUST SYTEM AND NO ONE WILL TOUCH IT. MAX CARE TOLD ME, THE AFTER MARKET ADD ONS ARE NOT COVERD, BUT DOES NOT VOID MY WARRANTY. THEY COVER EVRYTING ON THE CAR AND THE ENGINE FROM THE EXAUST MANIFOLD AND BACK. THE TURBO IS PART OF THE EXAUST MANIFOLD; SO IT IS COVERED, BUT NOT THE CAT. I ALMOST GOT REAR ENED WHEN I LOST POWER. .
THERE SHOULD BE A RECALL FROM GMC TO FIX THIS ISSUE. OR, CARMAX SHOULD WORK ON MY CAR WITH THE WARRANTY THEY SOLD ME. THANK YOU, PAUL.
