I got a new maf sensor. To install do I have to unplug the computer or battery, or just swap em out? Also, I was looking at a hose that goes from my tb, to my valve cover on my passenger side. I think its the pcv. I didnt see any kind of valve though. is that not the pcv?

 

Just swap it out, and no that's not the PCV valve. PCV is on the driver side, about halfway back on the intake manifold

(may be slightly different on your 94)

 

The line from the throttle body to the passenger side valve cover is the line that supplies fresh air to the crankcase, so the PCV valve can pull it through the engine to remove the harmful blowby gasses. Part of the PCV system, but does not contain the valve, as was explained above.

The PCV valve location is the same on all year LT1's. Its just the vacuum hose that's different, with the 93/94 engines having a u-shaped hose that connects back to the side of the intake, while the 95-97's run the vacuum source to a port under the throttle body.

 

alright. thanks for the help
