Ok, My Trans Am has been acting funny ever since i got it. i bought the car about a month ago. it is a 1995 lt1 a4. every time i try to floor car car from a dead stop or rarely a >10 mph roll the car will basicly act like it has traction control, once the car actually died. the engine basicly dies, rpm's drop drasticly, but comes back to life. my fuel pump went out, but was replaced. that was not the problem. some of the dash lights come on too. "secutrity", also, the ABS light is always on.

please help, this is a really frustrating problem. i really love this car...

Try to borrow a scanner or a multimeter and check the TPS voltage at WOT. Good luck. My .02

Bad fuel filter?

Clogged injectors?

Vacuum leak?

If its bad TPS the car will still run pretty much fine, it goes to speed density tune. Mine went and the car ran perfect, I even unplugged it and it ran perfect. And no SES light, but it did show up on the scan.

i was also thinking vaccum leak. the fuel filter is new, i guess i'll throw some sea foam at it too. whats the best was to find a vaccum leak on a car like mine?

Do you smoke? Blow smoke into the vacuum hose for you brake booster (remove the check valve). Just remember to plug the throttle body nice and tight with a plastic bag and some rubber bands. When your intake system is full of smoke it will seep out of any leaks.

You can come over to my house and borrow my smoke machine.

Carb cleaner. While your engine is running spray small squirts of carb cleaner near any common leak points (i.e. fuel injectors, manifold gaskets, vacuum fittings) if there is a leak and you hit with some spray your idle will smooth out a bit. Try to get the carb cleaner with the red tube that attatches to the nozzle.
