Re: 1996 Blazer, poor acceleration, poor gas mileage

Well, I pulled the MAF sensor for the second time. It was absolutely filthy. Caked with black gumk, i assume is oil residue from my K&N air filter i pulled from the vehicle a couple of months ago. Surprised i am still having residue on the MAF wires. Anyways, I took it off and disassembled it. I dont think i did that last time. I think i just sprayed it through the screen last time. So, i took it all apart and used some q-tips sprayed with carb cleaner. The gunk came right off. Carefully wipe down any gunk left on the wires and gingerly wiped down the three wire leads that go across the center of the MAF. took my time and wiped them down a few times. Everyone that says they are very fragile is correct. Carefully blew out the whole thing. Reassembled it. Before installing it i cleaned the air temp sensor( I think that is what it is) just after the MAF. I also cleaned the gunk from the throttle body. and wiped it down with a rag soaked in carb clean. Made everything look nice and shiny again. Put everything back together. Put my foot to the floor when starting it the first time due to all the carb spray in the intake. Started right up, seemed to run smoother. Let it run for about 10 minutes. Pulled the truck out of the drive, dropped it into drive and punched it. It smoked the right rear tire. Something it had not done in like 3 years. Now I step on the gas and it jumps. From 20 mph, i jump on the gas, it downshifts like now, the whole front of the truck hops up and it actually takes off.

Now, hopefully it stays this way. We'll see in a few weeks after it has had a chance to run for a while.
