Is This A Blown Engine? Grand Prix 1999

hi all....the local shop doesn't open till monday and I would like to hear your thoughts.

1999 Grand Prix GTP 163,000 km

I pulled out of a parking lot stepped on the gas for about 3 seconds....about 3/4 gas (the supercharger meter read about 1/2 way up) then put on the brakes and signal to turn into a side street.

As i started to make the turn i noticed the steering was not being assisted...came to a complete stop 1/2 way through the turn....the car was off. Weird, thats never happened before. I started it and it stalled immediately. I started it again and gave a bit of gas and a minor amount of smoke blew by the car from the tailpipes....the engine would surge to 1500-2000rpms then drop right down to almost stall then back up, then down to almost stall...repeat. I let it do this for about 30 seconds noticing the lights going bright and dim with the rpm then turned it off not wanting to damage anything. Putting it in gear to pull over to the curb made me sure parking it was the only thing i could do. It was't really sputtering but it wasn't smooth.

It is winter, maybe -1 celcius at the time. I'm sure there is oil in it. The engine has been fine up till now.

Any ideas....I just cant wait till monday.

Thanks

Sounds like a blown engine. Time for a new one.

Close the hood, take it to a shop. If you don't know what a vacuum hose is you have no business under the hood.

What do you mean by blown? A blown engine is like throwing a rod or worse. If you had a thrown rod/blown engine you would know it by a loud knocking and heavy smoking. And at that speed you say you were driving its highly unlikly you threw a rod. Chance are your problem is not mechanical but in the fuel, electrical or computer system. Those engines are known for intake gasket problems not for blowing.

Good answer FBR. Take it to a shop. My guess is thats its electrical. Does the "Service Engine Soon" light come on?

i agree franky. (i used the words 'blown engine' as a good eye catcher in the subject line and should have expected those types of responses) . After talkin to the mechanic and going down to the shop i am not too optimistic. They have had it on the hoist and computer for hrs and cant find why one of the cylinders is flooding like crazy. He said he would keep on it but suggested the computer may be pooched. I would have assumed their computer would be able to determine if my computer was gone but, again, I am no mechanic and this dude is the best in town so I'll have to trust. I will reply to the group with results.

thanks to everyone for any help and suggestions

well....it was the mass airflow sensor. The mechanic said it was one of the first things they checked/cleaned but it didnt throw any errors so they assumed it was ok. After checking everything else they went back again somehow found that that was it.

mas+oil change+time=$600

yay
