Hello All........Need your Help

I have 1995 Grand Am...the car keeps stalling out on me.i've taken it into the the shop.at first they told me it was due to a crank shaft sensor...which was replaced....did not fix the problem...then i was told maybe I need new plugs which i've replaced with ngk platiums...did not solve my issue.i've even changed the wiring......then they said ...hmm it could be your fuel filter...replaced it...with no results....Please offer any suggestions.

the car has almost 300k ...was running like a charm till recently....

When does it stall out? When idieling? When accelerating?

I don't know, but that information might be helpfull to anyone who does :)

Have you scanned it? The mil may not be illuminating, but check anyway to see if it's throwing any codes.

i had the same problem with my car. they replaced the wires, coils, fuel filter, etc....only to discover that it was a loose ground wire. hope this helps.

maybe a pinched or blocked fuel line?
Have you run any injector cleaner?

GOT IT !!!....after spending about $1000 on replacing all these parts that should not have been........finnaly fixed the proplem....it was the TPS sensor........either I have had bad mechanics....that wouldn't operate their scans....or diagonis the problems.....or this just wasn't on the radar.....but once we replaced the TPS sensor the car runs like mu old baby......thanks for all of your suggestions...I appreciate your help
