Still Rough Idle After All The Cleaning

[arnoldv]

1991 Mazda Navajo 111,000 4.0L V6 OHV

My car still idles rough after I cleaned my IAC, MAF, Fuel Injector. Changed my spark plugs too. Can it be the TPS?

Plan to do:

Oil Change
Oil Filter
Fuel Filter

What else is there to do????????

After doing all that stuff, you could try resetting the computer.

Actually, I unplugged the negative cable before I did the cleaning. Hope that does the job.
