where is the intake air temperture sensor on a '89 L98 350 TPI engine? I need this info asap please help

Under the plenum.

thanks, I found it on the FAQ site but I still wanted to double check. Just don't wanna screw anything up. I bought a Gorillaz Stage 2 Chip and it came today. WAITING for engine to cool down before I can install it though! Anxious to say the least.Not hoping for big just a lil zap

Your welcome. They are a pain to get to. I remember forgetting to plug it back in one time, way back when, when I had the plenum off.

Will that location change for a 1992 Z28 5.7 TPI ???

Does Gorillaz tell you to move the MAT/IAT sensor to use their chip?

If I had to guess he's going to install a resistor as a jumper over the two pins of the harness there.

In all honesty, I wouldn't recommend it. Return that chip to the manufacturer saying it is defective. Buy real tuning stuff or pay money to have your car tuned the right way.

We all say HyperTech chips are crap...have no idea what a Gorilla chip offers you.
