Please someone help!!
My car has been acting weird. It will bog when I accelerate but as soon as it hits 2000 RPM it regains full power. It's almost like a nitrous shot at 2K RPM. Under 2k its boggy. Doesn't seem to respond no matter how much gas I give it the car responds the same way. Funny thing is that it doesn't do it all the time. It can go for days and act normal but out of the blue it will start with the problem again. It's only started doing this in the last couple weeks. I am completely stumped. What could be causing this? Is it a bad sensor or something? I don't have a cat on the car so I know its not a clogged cat. Oil pressure is normal so is engine temperature. It will idle fine as well. Please someone help me out I don't need this right now. This is making driving in the rain very dangerous since the sudden power recovery at 2k causes the back end to slip. Please help me you guys. Thanks in advance.

i know this sounds really funny but try disconnecting the battery for a couple of minutes and then hook it back up. i had that same kind of problem on a car of mine. i never found out what was wrong with it but that would cure it for a couple of weeks and then i would just unhook it again.
let me know if this helps at all.
thanks,
theo

I need a permanent fix though. I don't want to cover up a possible bad problem. Thanks for the suggestion though. I will see though if disconnecting the battery does anything.

Problem is fixed. I thought I would post the result for people that might search and come across this thread with a similar problem. After replacing the IAC and adjusting the minimum idle screw with no result my car gave a code. Code 51 which is a prom/mem cal error code. I put in a different chip and the problem is solved. So if your car is acting like mine is make sure your prom is secure in the ECM. If everything is tight try changing the chip. Hope this helps someone
