Doh!

I just had to throw out a good speed density tune and have the car reflashed to stock. I then replaced the SLP MAF sensor (which has been unplugged for months) and added a Predator tune. I'm throwing 4 codes:

1) P0102 Mass Air Flow Circuit. Low Input
2) P0327 Knock Sensor 1 Circuit, Low Input
3) P0801 Reverse Inhibit Control circuit Malfunction
4) P0803 Upshift Solenoid Control Circuit Malfunction

The first problem is what's killing me. It's a brand new MAF Sensor, and started throwing the code before ever running the car for any length of time. Here's what the Predator tells me with the engine at 165*:

MAP = 2-10; Idle = 4 WOT = 10
Spark = 21.6* - 40* depending on the throttle
MAF = 0.311 b/m
HO2S Bank 1 Sensor 1 = 790-850 Mv (higher than the others)
........Bank 1 Sensor 2 = 490-535 Mv
........Bank 2 Sensor 1 = 460-500 Mv
........Bank 2 Sensor 2 = 465-510 Mv
KR = 0*

The Low frequency Knock Snesor went bad a while ago, and I'm about to do a Head/Cam swap, so I'll replace it then.

The Reverse Inhibit malfunction is because the guy who installed my Mcleod clutch screwed up.

The Skip Shift hasn't worked since I installed 4.10s, but it never threw a code for it before...

So, is my O2 sensor bad (Bank 1 Sensor 1)? Or is it something else I need to do? Any help will be lavishly praised...

 

I had a similar combination of codes after blowing a fuse. Check the fuse panel under the hood.

 

Thanks, man. That was it: the Engine Sensor fuse (20 amp mini). You're the greatest! I owe you...

Gotta love the 60-cent fixes

 

Awesome! Do a burnout in my honor and we're even.
