Hey guys my 1997 Ford Thunderbird v8 is misbehaving lately. When I turn the wheels while going slow, such as pulling in the drive way, it feels like the car is going to stall. It feels like it is about to stall when I turn on the a/c when not in motion like at a red light. Today I noticed that when the car starts it revs up, then dips to about 400-500 rpms, then goes back up to normal idle speed at 1k. You guys have any idea what could be causing this? A friend of mine says he thinks it could be a dirty MAF sensor, but I haven't had time to check that yet. Thanks in advance for your help!
Any ideas?

The IAC could be sticking. That would satisfy all of the symptoms you have described.
Your vacuum hoses could be leaking
The PCV valve can stick, causing the engine to act like there is a vacuum leak.
How good are your spark plugs and wires?

Clean your throttle plate and bore, and the IAC valve.
Also, check for any vacuum leaks in lines, connections, or manifolding. Really look and take your time - trace each one.
