Hey guy's heres the lowdown. 1986 Camaro 305 tpi. My Camaro has been throwing code 34 and 33, and 44 for some time now, and I suspect the MAF sensor is going bad. I have tried different relays to no avail. Heres what my cheap autozone scanner reads.

Engine Idling-

MAF GR/Sec- ranges from 247 to as high as 1036 at idle. It should stay consistent and not move much at all correct?

Here's a couple others i would like to know if are in spec, since I don't know much about what the specs should be for our cars.

Injector pulse width reads 91-96 at idle

BLM- 130

O2 crosscounts-86-172

O2 sensor is constantly reading lean. I know thats not right for sure.

Now yesterday I took off my Throttlebody, removed the IAC, cleaned it as per Vaders instructions, cleaned the heck out of the TB butterfly's, and the IAC passages. Reinstalled the IAC and T/B with a new gasket. Reset TPS to .54 volts at closed throttle. Reset Min air idle as per vaders instructions, and the car doesnt want to idle on its own 98% of the time. I unhooked the PCV hose, and it idled on its own since more air was being sucked in i guess. Car is still throwing MAF codes 33 and 34 and 44.

Please help me guys i need my car!

 

Those numbers seem way out of whack. Its been awhile since I hooked up to a MAF TPI car, but of all the other Port Fuel MAF cars (3100, 3400, 3800, 5.3L & LS1), they have all been pretty stable, somewhere between 5-8 Gram/Sec at idle.

Also, injector pulsewidth was usually 2-3.5 miliseconds.

 

Yeah I defnitely don't think these numbers are in spec. I'm pretty sure a MAF sensors readings should'nt be that high and jump like that at Idle. Exhaust is always reading lean too. I do have some exhuast leaks come to think of it, but only after the O2 sensor. O2 sensor is a OEM bosch unit and it's not even probably 2 months old. AARRRRGGGGHHHHHHHH!
