Car Forum / Pontiac / Pontiac Cars / March 200798 gp engine dies
last night my 98 gp 3800, supercharged, auto, 103000 miles died while approching a stop sign. When restarting it would idle for less than a second. Giving it throttle it yould rev to 4000 rpm's but as soon as I let off it would die. I was able to get it to town (20 miles) by keeping the throttle wide open. Towed it after I got it in town. The SES light has been on for a couple of months, that code was an evap. problem. Other than that no signs anything was going out. Any advice would be appreciated. pigpen I would checkd the DTC's again. Did the light flash at you & then come on solid? Does it run ok keeping your foot on the throttle? No power , skip or anything? > last night my 98 gp 3800, supercharged, auto, 103000 miles died while > approching a stop sign.

Does it run ok keeping your foot on the throttle? No power , skip or >anything? light stays on. Traction control light was off and on a few times. With foot in it, runs against the revlimiter and when foot is lifted engine stops pigpen >> last night my 98 gp 3800, supercharged, auto, 103000 miles died while >> approching a stop sign.

It may have come off if you had a bad idler pulley bearing. > last night my 98 gp 3800, supercharged, auto, 103000 miles died while > approching a stop sign.

That was the first thing I looked at besides the fluids. >> last night my 98 gp 3800, supercharged, auto, 103000 miles died while >> approching a stop sign.

Had to cut the fuel line because the fittings wouldn't come apart. Then the car would idle for about a minute before dieing again. Would still run WOT. Pulled the connectors of all the sensors one at a time and there either was no change or the car wouldn't start. Wound up takeing it to a shop up town. the problem turned out to be a fuel pump regulator controller that is known to be faulty. It was replaced and relocated. Hopefully the pony won't give me any more trouble. Pigpen |
