95 Grand Am BIG PROBLEM!

Well my wife just called me telling me that the car is bad off again...telling me that the speed is constantly fluctuating between 20-30mph and back to the true speed. and the weird thing is that she is NOT depressing the gas and the cruise is NOT set but yet the car keeps goin...what are the problems? im thinking along the lines of a tranny prob. possibly the governor or input/output speed sensor...a little bit of intel would be great fellas. thanks

Is the Check Engine Light on?

Nah Dan the check engine light isn't on...I cleared all the codes a few weeks ago on my motus scanner...but neway my thoughts are the throttle linkage...im gonna spray em real good and make sure that they are not binding and then the TPS and the MAF sensors. anymore input from anyone would be great...thanks

90% its a stuck IAC valve, 5% its a bad TPS, the other 5% is vacuum leak/fuel pressure reg or intake leak

Fab, Richtazz went right where I was going to go, I was thinking along the lines of a vac. issue. You may be right about the linkage but I would think the a sticky linkage would have caused another issue at start up.

Good luck,
Dan

Speaking of stuck valves, could it possibly also be related to a stuck open EGR valve? I'm not sure if that would cause it, but it might be worth pulling off and checking / cleaning.

thanks guys for all the input...greatly appreciated but I haven't had the chance to check anything yet especially considering i have no tools AT ALL lol but thanks though...if anyone can think of absolutely anything else that might be causing these symptoms feel free to post up.
