Engine codes

[96awdgsx]

Ok so im troubleshooting my cars boosting problem that ive posted about. I went to autozone tonite to check my codes and i got these:

p1105 Fuel air metering control malfunction/ FUel pressure solenoid malfunction. Now ive read that because i have a walbro 255 that i dont need the vacumm lines attached to the solenoid and ill always get this cel. is that true?

I also got

po105- Barometric pressure sensor malfunction. Im not sure but could this be from my Pot Mod fix that i did for my random MS? This code never came up when i first intalled it but im just wondering if it could be the problem.

ANd the last code i got

po141: 02 sensor heater malfunction.

COuld someone please give me some advice as to what these codes actually do to my car because this may be why its running like shit.

thanx for reading.

sounds like a bad MAF and o2 to me.

glen, you dont have an fpr selanoid. The line from the fpr is directly on the intake mani hence the first CEL. I would guess since the pot mod affects the barometric reading the ecu sees, that it would throw a CEL. Second one is something wrong with your o2 sensor. Replace it. One thing i dont get that luke said, how do any of those CEL's affect his MAF sensor?

"Fuel air metering control malfunction"
Only air metering I know of comes from the MAS ;)

glenn,
I was actually READING through my factory manual.. trying to pinpoint my spark problem and I came across your code.

definitely the MAF

Thanx man, im still trying to find someone who will swap maf's with me so i can test it out to see if this is the true problem. Anyone in the north jersey area?> I cant really drive it far distances.

I wouldn't jump to the bad maf conclusion yet. The first code means the FPR solenoid is disconnected, which it sounds like it is (electrical, not vaccum). The baro mod can cause that code, and the faulty o2 is usually just a dead or unplugged o2.

Plug the fpr soleniod back in, reset the codes and see what comes back.

the o2 code is bank 1 sensor 2.. meaning it's the rear o2 sensor after the cat. Since glenn doesn't have a cat.. that code would pop up.

besides, I told you can use mine if you're willing to drive your shitbox to my garage where my shitbox is :lol:
