Just a note on the dirty MAF sensor. I used to have a few S10s in the family. All but one had the 4.3. Three of the V6 motors had K&N air filters on them. The ran great, but within about 3 to 6 months, they started to throw MAF codes. Come to find out after talking to a service manager at my Chevy Dealer, it was not uncommon to see the K&N oil collected on the screen of the MAF. I did the same thing with the MAF cleaner and it fixed the prob. I also cleaned the filters and reoiled and let the oil sit for about a day before reinstalling.
