98 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.

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?

Check the supercharger belt also. It may have come off if you had a bad idler pulley bearing.

That was the first thing I looked at besides the fluids.

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

Get the MAF (Mass Air Flow) sensor looked at sometimes those can cause a problem like that, my friend has a 2001 VW GTI VR6 and it did the same thing so we unpluged the MAF sensor and cleaned off the contacts and got it working again, try running the car with the MAF sensor unpluged, in case you dont know where it is it should be on the same tube as the air-filter box.

Follow up on the stalling engine

Fuel filter was replaced as per the shop reccomondations. 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.
