Im lost again...
 

Ok, this seems to be the ongoing debate in the office as to what the hell my car is doing.

Remember those two codes I told you about? Well I cleared them, and they're back again. I changed out that O-Ring on the injector, and the fuel leak went away, but seemingly, the codes are sticking around.

Heres a refresher of the two codes:
P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1.
P1232 Low Speed Fuel Pump Primary circuit failure.

Now, here's where we sit in the office on this. We have a few possible scenerios.

1. The ECU hasnt taken to the changes yet and needs a few drive cycles to get everything set back to normal.

2. The Bank 1 02 Sensor heating element is shot, hence why its not reading properly.

3. That control box we were discussing is shot, but im still not having bank 2 being thrown. (??)

4. I could have SWORN I felt a vacuum leak (possible) on the rubber piece that goes on top of my FPR and connects to the plenum. I have to check back up on this, but I wouldnt think that the unmetered air would throw the fuel pump primary circuit failure. However, if it is this thing on the FPR, then it might make sense that it might cause the Fuel pump issue and the lean issue, but you would think that, once again, it would show banks one and two.

5. Gremlins are in my fuel lines and are trying to destroy my car (very possible, as they are jealous of my car, and if you cant have something, you destroy it).

6. IMRC box that I put in is bad (not sure how this would be possible, as im not getting a code thrown that the controller has failed).

Im about to explode. What are your thoughts on this since we have been bantering back and forth on this issue?

I'll check wth Dennis our driveabilty tech when he gets back from a road-test and prob lunch::p

That rat bastard :).

Cool cool. Give me a call or post here.

Denny said 1st thing to-do is swap the O2's from 1 bank to the other. call me later as the rest has to-do wth fuel trim, vac leaks, bad ccm or fuel pump

Found it!!

T-Fitting was cracked from the rubber piece that goes onto the FPR! I heard that sucker, looked, and poof, there it was!

shambles...you suk @ teh mustangs. go drive a 'maro. :loser:

No, the last guy who had the car just didnt take care of it. I'm just fixing it up to get it into better shape!

good job::p
