Just checked codes, need some help!

[SHODOGG]

My car has been acting real weird lately. Idle is totally messed up, sometimes the car will die when I push the clutch in while coasting/braking to a stop. I have a PRO-M 80Maf which explains the MAF code I got, and I think its a possibility that I have a vacuum leak somewhere in the intake manifold as my rubber hose connectors and the metal clamps that hold them on aren't all in the greatest shape. Here are the codes I got:
KOEO
157: MAF Circuit Below Minimum Voltage (Probably the PRO-M is at fault there)
176: HEGO Sensor indicates System Lean (LH) Bad 02 maybe?
211: PIP Circuit Fault (no idea what this means)
542: Fuel Pump Secondary Circuit Failure
556: Fuel Pump Primary Circuit Failure (Not sure WHY its throwing codes for the Fuel Pump as its a Brand New Walbro 190lph that I had put in back in August).

KOER
136: HEGO Sensor indicates System Lean (LH) I must have a bad 02
411: Cannot Control RPM During self-test low RPM Check

So what do I need to replace/check out on my car?? HELP PLEASE!! frown

O2 Sensor and CPS

 

[Mike Kopstain]

The o2 code refers to the MAF code. Disregard it and the MAF code and get that MAF recalibrated or fixed.

211 - is the CPS sensor. Reset your battery and see if that comes back. I know for a fact that that is new since I'm the one that replaced it!

542 means you stalled the car once upon a time. Disregard.

556 might be related to 542 or may not. If the car is not stalling out, I wouldn't concern myself with it.

411 most likely relates to the rough idle that usually accompanies an aftermarket MAF that is out of calibration. I would take care of that MAF before it takes care of your other sensors.

Damn the PRO-M Maf!! Damn it to ****!! lol thanks though guys, I appreciate the help. Mike, you don't think my CPS would have already gone bad do you? And do you think that a vaccuum leak in the intake manifold would cause any of this cause when I put my BBB's in, the intake couplers wouldnt tighten as well as they did before.

 

[Mike Kopstain]

The vacuum leak could definetly be the cause of the uncontrolled idle code.

If it were leaning the car out though, both sides would show lean. So I'm gonna stick with the MAF being the major culprit here.

As far as the CPS, has the car cut out at all?

 

[SHODOGG]

well, like I said theres been 2-3 times where I put the clutch in at speed to brake to a stop and the idle goes down and the car died. The idle has been real erratic lately overall, though. I don't see how the CPS could be broken already shrug

2 questions:

Have you replaced the IAB?

Does you idle stay higher while you're moving, then drop down when you stop?

 

[SHODOGG]

I haven't replaced the IAB but I mean the car has only been doing this since I put the PRO-M in the car, and it only got worse when I put my BBB's in the car. So It has to be a combination of the MAF being a POS(although it does give me slightly more power) and a possible vaccuum leak. Also, I've cleaned my IAB at least 3 times since I've had the car. headbang dang SHO's!

 

[AutoSHO]

Does putting the stock MAF back on fix it still?

 

[SHODOGG]

It should but I'll know for sure this weekend. Unfortunately the stock MAF is at home and Im at school headbang

I hate my f*cking car. Anyone want to buy a "rare" black on black 92?? finger
