NHTSA Complaint #759436 — 1994 OLDSMOBILE ACHIEVA

ENGINE LOST POWER AT 65 MPH ON FREEWAY, ABLE TO PULL TO RIGHT SHOULDER, ENGINE WAS NOT HOT, NO CHECK LIGHTS WERE ON, CHECKED OIL & WATER LEVELS, OK, TRIED TO RESTART ENGINE BUT IT WAS VERY NOISY & BACKFIRING, AND WOULD ONLY RUN AT FAST IDLE. SHUT DOWN, CALLED TOW TRUCK. MECHANIC TOOK A COMPRESSION CHECK, NO COMPRESSION IN # 2 & 4 CYLINDERS. THIS ENGINE HAS A TIMING CHAIN, NOT A BELT, TIMING WAS CHECKED, FOUND OK. PULLED HEAD & FOUND THAT VALVES ON THOSE CYLINDERS HAD HIT PISTONS, BUT NOT ENOUGH TO HURT SAME. PRESSURE CHECKED HEAD, GROUND VALVES (WERE NOT BENT), REASSEMBLED ENGINE, STARTED SAME & IT WAS MISSING & BACKFIRING THRU THROTTLE BOBY, SAME AS ON FREEWAY. MECHANIC GOT ON THE INTERNET LOOKING FOR ANSWERS & HAD NUMEROUS REPLIES THAT COIL HOUSING WAS DEFECTIVE. REPLACED SAME, HAVE PUT ALMOST 1000 MILES ON ODOMETER WITH NO PROBLEMS....DUE TO THE FACT THAT OLDS HAS COME OUT WITH A REVISED COIL HOUSING & MECHANICS ALL OVER USA REPORTED HAVING SAME PROBLEM, I FEEL THERE SHOULD BE A PROGRAM INITIATED FOR OLDS TO REIMBURSE OWNERS THEIR COSTS AT THIS LOW MILEAGE FOR THIS PROBLEM. MY REPAIR COST WAS $1031.17, WHICH COULD HAVE VERY EASILY BEEN $4000.00 FOR A NEW ENGINE IF THE PISTONS HAD HIT THE VALVES ANY HARDER. OLDS REDESIGNED THE HOUSING, WHICH INDICATES THEY WERE AWARE OF THE PROBLEM. OLDS REFUSES TO HELP PAY ANY OF THE BILL BECAUSE THE PROBLEM "WAS NOT DIAGNOSED AT A GM DEALER" THEY ARE SENDING ME A DENIAL OF HELP LETTER. PLEASE RESPOND WITH YOUR THOUGHTS ABOUT THIS PROBLEM.. *AK
