00 grand am will stall at highway speeds

[allanrigaud]

I have a 2000 grand am, every time im on the highway , around 70 or 80 mph the car will stall... so i have to pull out the road and wait like 5 minutes to turn it on again , and then i have to take avenues to get home..

I already change the fuel filter , but it seems that is not the problem. Its weird, because if i drive around avenues the car will run just nice, but on the highway will stall.. what i could be??

Only way to find this to check for spark and injector pulse as the first step in the diagnostics, might see if it starts with starter fluid also.

Did you get the problem diagnosed? I'm having the exact same issue with a 2000 SE with the 4 cyl engine. 20 miles or so at 70mph and the engine just cuts out. Wait 5 minutes and it starts back up fine. Kind of dangerous when your in alot of traffic or construction zones with no place to pull over...

Sounds like the computer is killing the engine.

Just cruising through the GA forum and came across this one. I have a 1997 Blazer that was doing this very same thing and I finally chased the problem down to a junk ignition switch in the steering column. Whether or not it is the same problem or not. I know it is not the same column that is in the GA's but who knows.

Problem resolved for me - Fuel Filter.
$15.00 at N@pa and 15 minutes to change (even without the special tool)

I never would have thought a fuel filter could intermittently cause the car to quit.

sometimes a faulty crankshaft position sensor will kill the engine, after it gets hot.
