Grand Am Pontiac 2002 issues?

[Eveamlizya]

Ok, my friend's car has been having issues. They said it's been going on for a couple years always in the summer and it only does this once and then it's fine for a while. We were driving yesterday (it's in arkansas so it was feeling about like over 100 degrees yesterday and humid) and the car just shut off while he was driving. We pulled over and tried to start it again and it would try to start but wouldn't...after waiting for a little while it finally started and we drove a little more and it did the same thing again. There was one of the times when we stopped that I saw a white hazy smoke which looked like cigarette smoke but wasn't. We finally got it to start again and drove into a parking lot...went to a restaurant and ate lunch then went back out and it started perfectly fine.
We've asked a couple people about it and we've got a couple ideas as to what it might be...the main idea is the fuel filter. They do have a major oil leak and we don't know where it's coming from...they just got a new starter.

Any ideas would be great...

it could be overheating best thing to do is check the coolant. then the oil leak might be the intake gasket or the cylinder head gasket. maybe your engine turned off because of that too maybe it has low oil and it was getting poor lubrication or the oil was not cooling your engine enough oil takes 75% of the heat in your engine i hope this helps =)

Go to the "GM Litigation" web-sites. It is VERY possible that your intake manifold and gasket are mixing coolant with your incoming air. This would cause the smoke you mentioned. Improper oil use can sludge over your engine seals and gaskets, too. Fix the intake gasket, de-sludge your engine, and only use oils that state on the label, "designed for use in GM vehicles." SEE???
