Engine Performance problem
1996 Oldsmobile Bravada 6 cyl All Wheel Drive Automatic 160K + miles
I had a crack in my water overflow valve where my thermostat is located. I took the OEM air intake assembly apart, I took the two sensors and placed them back towards the firewall, disconnected the throttle cable assemblies from the throtle body, and took out the old valve and thermostat. I put the new valve and thermostat. I dropped one of the bolts under the alternator, and had to partially remove it to get the bolt. I finally got everything put back together, and started the engine. Everything was fine for a couple of seconds, and then my idle started fluctuating. RPMs dropped to about 500, and then shot up to 2K. From what i can tell, it could be a MAF issue. Also, I replaced the serpentine belt, and ran the engine with no problem before I started working on everything else. I need to confirm that the MAF is the most likely problem as this is my only vechicle.
