Tl* the contact owns a 1996 pontiac bonneville. The contact stated that several attempts had to be made before succeeding in starting vehicle. The vehicle was taken to a mechanic where the failure was located at the intake manifold and oxygen sensor. The intake manifold cap was melting and causing oil to spill. In addition, the failure was producing white smoke from the tailpipe exhaust. The vehicle was repaired but the contact was unsure as to the exact repairs made to the vehicle.

This car belongs to my elderly mother which she bought used and has been an on going problem! Occasionally when starting the car, the engine will backfire, after starting it would run ok. The car now does not run as the intake manifold is broken from the backfiring and almost caught on fire the last time it was attempted to start the motor! According to pontiac there is no recall on this car by the VIN number!!

Tl* the contact owns a 1996 pontiac bonneville. While driving at speeds of at least 10 MPH or while sitting idle, the vehicle would stall without warning. The power windows, seats and fuel pump would become inoperable as well. The contact would recharge the battery and once fully charged, the vehicle would operate normally for a short period of time before stalling again. The vehicle was taken to an independent mechanic but they could not duplicate the failure. The failure persisted. The contact also stated that it would take several attempts to remove the key from the ignition when shutting off the engine. The vehicle was taken to a different mechanic where they could not duplicate the additional failures. The mechanic suggested that the ignition anti-theft controller was faulty and caused the vehicle to stall. Although there was a recall for the failure, (the federal safety agency campaign id number: 95v204000: electrical system: ignition: anti-theft controller), his VIN was not included. The failure mileage was 97,000 and the current was 98,000.

Electrical system problem. Windows quit working, directly related to engine not firing up. Also affects door chimes, security, seat controls, interior lighting. Multiple attempts of trying to fix problem, battery cables, battery, replacing ignition wires to no avail. Problem continues to worsen. Had to have towed to dealer, since local mechanics could not find initial problems. Car does not run at this time. I even put on a fuel pump(which didn't need replacing) due to shut off of motor. When windows quit working it also affects the fuel and spark. We think its in the computer and/or security system.

My 1996 bonneville started acting up, roughly idling, and hesitating when taking off. There was loss of power, poor gas mileage, car would shut it self off while driving down the highway.check engine light came on and started flashing. Took it to auto zone to get it checked. Scanner idicated that it had multiple misfires, and that my map sensor was bad. Replaced map sensor. Still didnt change on how the vehicle operated. Replaced one of coil packs, still nothing. Put new plug wires and nothing cahned. New oxygen sensor installed, and still nothing. Changes. Over all I just got done spending $150.00 on this car and I cant even afford that, and still have not resolved the problem. I replaced basically everything that the computer came up with. What can I do here to solve this problem without me hurting my financial status, and me blowing the car up.
