Engine Fuse for the Mass air flow?
Well we just got the motor and everything back together and its been running sluggish after it warms up and what not.
We scanned it and found that the Mass air flow sensor wasn't even picking up anything and staying at a constant 9.
My friend mentioned that it will blow the engine fuse and cause the MAF sensor to do that.
Anyone know where it might be located? We searched in the one under the hood and the one in the side panel on the car and couldn't find it.
btw its a 95 trans am

Shoebox has the wiring diagrams for the 1995 LT1 on his website. It shows that the MAF sensor is powered off fuse #5 in the instrument panel block. Your Owner's Manual also will tell you what loads are on which fuses. If you don't have an Owner's Manual, Shoebox has a link to online copies of the manual.
The Owner's Manual shows #5 (PCM IGN) also supplies the PCM, fuel pump relay, and theft deterrent module, so its not likely that fuse is blown, unless the engine is not running at all.
Turn the key on and check to see if you have 12V on the pink wire in the harness connector for the MAF, when measured across the black/whie ground wire. Check for damaged pins in the connector.
