88 ranger 2.9 surge help?

I have a 88 ranger 4wd auto with a 2.9, while accelerating between the 2000and 3000 rpm range i get a slight surge in the engine usually around 50 to 100 rpms. Anyone had experience with this i would like help so i don't wind up spending money on unnecessary parts ect. Also a little background on truck
I bought it after it had been sitting for some time, changed fuel filter, run two tanks of injector cleaner, and cleaned throttle body area?? thanks

Try the IAC solenoid (AKA:valve)- I think the 2.9 used one in '88. Also check whether the PCV valve is not seated properly, is wearing out or partially plugged.

Hope this helps... they're good places to start anyway..
