I have a 95 s14 with a stock ka24

recently started to bog out, couldn't keep idle nor rev past 2k.
It smells like gas everytime the car is revved and black smoke comes out the tailpipe.

just recently changed the o2 sensor and bought a new maf sensor.
After changing the maf, it could rev way past 2k rpms but still bogs and dies if given no gas.

any input at what the problem can be?
want to get this car fixed asap.

i had the same problem a few months ago but after changing the o2 sensor it went away.

UPDATE 11-25-12: Car idles fine without the maf plugged in; just cant rev past 2.5k rpms. But when I plug the maf in, the car suddenly dies. (tried two different mafs)

First
Pull codes (I know you have some)
Second:
check the MAF wiring. Sounds like a bad ground
Third:
Check for vac leaks

your car isnt supposed to rev past 3500 when the MAF is unplugged, that's normal. Its in safe mode and it runs super rich.

Maf wiring issue possibly. Follow procedures in FSM to check if everything is in spec.
