Rough Idle

I have a 89 150 5.0L that idles rough. It will run fine and dosent seem like it is losing any power but the idle is rough. I am not good with diaginostics so if anyone could help be it would be very helpful.

Could this be the IAC and if so where is it located.

Try cleaning the IAC and then run a tank of Techron through it. Highway miles also helps.
