i need some help i gotta 01 z28 and she has treated me well the past 2 years. i just recently put a set of jet hot long tube headers on and had no problems at first. i figured out the hard way not to drive around w/o foward o2 sensors. i was driving home from work and she started sputtering really bad and the engine light started flashing at me so i got it home and parked it, nad it was spitting a code for the o2s. i got my o2 sensor extensions on and the o2s hooked back up. i started it up and it was still doing the same exact thing but it was shooting a new code. the code was "mass air flow sensor, low input" i drove it and it was still running like ****, so i made sure the harness was still plugged into the sensor and it was. i got on my diablo sport programer and my short term and long term was reading zeros across the board. so is my mass air flow sensor shot? or could it be something else?

I'm not sure why it would have hurt your MAF if it was misfiring. In other posts, people say that their spark plugs have fouled due to running no front O2's. That is the only thing I can think of.

some advice for some problems i gotta 01 z28 and she has treated me well the past 2 years. i just recently put a set of jet hot long tube headers on and had no problems at first. i figured out the hard way not to drive around w/o foward o2 sensors. i was driving home from work and she started sputtering really bad and the engine light started flashing at me so i got it home and parked it, nad it was spitting a code for the o2s. i got my o2 sensor extensions on and the o2s hooked back up. i started it up and it was still doing the same exact thing but it was shooting a new code. the code was "mass air flow sensor, low input" i drove it and it was still running like ****, so i made sure the harness was still plugged into the sensor and it was. i got on my diablo sport programer and my short term and long term was reading zeros across the board. so is my mass air flow sensor shot? or could it be something else?
My MAF does the exact same thing. I think the wires going into the plug on the MAF are fucked up. Every now and then I'm driving, everything is perfect, and it just falls on its face. SES light comes on for "mass air flow sensor, low input".
It usually stops if I keep driving for a while or I get under the hood and sorta push the wires into the plug a bit.
