I have a 1999 Grand am SE v6. Whenever I rev the engine or try to drive a little fast, the engine seems to cut off at around 3500 rpm. Does anyone know what could be causing this?? Intake and exhaust is all stock. Oil change every 3mo/3000mi. New air filter with every oil change.

Also, how much fluid does the transmission take. I would like to change the tranny fluid but there's no dipstick to tell when there's enough fluid. Please help.

Are you in gear or in neutral? If you're in neutral or park the cutoff is designed to keep the engine from being damaged. If its cutting off in gear something is amiss.

What do you mean "cut off"

Computer cuts off fuel to engine at 3500rpm on stock car while in neutral or park. Basically it keeps it from revving past that mark.

-edit-

To specify the cutoff is supposed to occur only at standstill.

Well yeah i know that but it seems he is actually driving it, like ya know, in gear. So by "cut off" does he mean the car just shuts off, dosent excelerate etc.

Spark plugs, wires, oil filter and oil(never know) fuel filter, o2 sensor, clean your injectors.

I want to say a fuel flow problem. Does this happen only when you gun it or anytime it gets to the 3500 rev mark?

I think "bonnor" is on the right track..................cheap too.........so even if it's not the filter you'll be glad you did it anyway!!!!!!!!
