I'm going to clean the MAF sensor tomorrow afternoon, and reset the computer. Is unhooking the battery, turning key on, hitting brake pedal and waiting thirty minutes good enough?

Also, i did use a Edge Evolution programmer to pull the codes..... it tells tranny line pressure, which i was checking.

How do you check O2 sensors, and roughly what do they cause to replace.

I cheched the tailpipe after a 50 mile trip today, and there is no soot in the exhaust, so i'm wondering if it's rich, or i have other problems.

And where do you pull seafoam into the vacuum line to clean it? I've never had to do much to this truck, so i have no clue what is what under there, lol.
