What are these codes and how do i fix them?

[2000 Tran Zam]

i have a p1133 code : manufacturer control fuel air metering

another p code i dont have the number, but its the one with bank sensor 1 being too lean.

i also just changed my o2 sensor about 30 minutes ago.

before i changed the o2 sensor, my a/f gauge didnt have any bars light up. after i changed it, it was hoovering in the lean red section.

what are those 2 codes, and how do i fix them? like i said, i just changed the o2 sensor out 30 min ago and i keep misfiring under part throttle between 2-3k rpm.

what else could be making me misfire? any ideas? please :help:

Did you connect it correctly and securely? Was it the front or rear sensor?

E:)

[2000 Tran Zam]

it was the front sensor, its in the bungs on my headers. and yes i torqued it down nice and snug the way it always has been. someone mentioned that p1133 code could be my maf? any ideas?

[eboggs_jkvl]

1133 is insufficient switching of the O2 sensor, not the MAF. How about electrical connections, didn't bend any pins on something did ya? Burn the wire on the exhaust?

[2000 Tran Zam]

the wire from where? the o2 extension or the o2 itself?

[2000 Tran Zam]

no pins were bent to my knowledge

[eboggs_jkvl]

O2 wire toward the PCM.

[2000 Tran Zam]

ya it seemed fine

do u think anything could ahve gone wrong when i spliced pin 69 for the a/f gauge? or would that not affect anything? it looked like a clean splicing and was taped up nicely

[eboggs_jkvl]

That'd just mess the guage up if it was bad. Still sounds like a plug wire or O2 wire is burned or damaged.

[2000 Tran Zam]

what if a plug went bad, is that a possibility? or you dont think autozone could have given me the wrong o2 sensor possibly? it fit fine though, and i just check the o2 wiring and the prongs on the end of both where it plugs into and the prongs themselves, everything is ok. im just stumped why its not working. and something has to be wrong cause im on the 3rd o2 senor in 3 months now...

[eboggs_jkvl]

Are you losing the same sensor? Are you running rich? Got oil blowing through?

E:)

[2000 Tran Zam]

it is the same sensor, everytime i replaced it, its been that same side, same bank. we did some dyno tuning, it was at 12.3

on the autotap, the bank sensor 1 was reading in between 60-90 even at part throttle, while the other one was reading between 50 or so to 950.

the injector pulse on the bad side was 4.3 , and the good side was 3.2 or so.

[2000 Tran Zam]

and where would i have oil blowing through, the tail pipes? i just noticed some stuff was spewing from my pipes, but i thought it could be water, or condensation.

[2000 Tran Zam]

ok good, i figured it out, at least its not misfiring at mid throttle anymore. i disconnected the pcm wire from the a/f gauge, and problem solved. i talked to chad, black02ss and he said same thing happened to his friend, IDENTICALLY. he thinks that when you take the signal from the pcm wire, since it splits up part going to the computer, and part going to the a/f gauge, only half the current or something is being taken in by the computer throwing things off.

so now my question is, how can i hook the a/f guage to work without misfiring and drawing so much power from the wire? :shrug:

[eboggs_jkvl]

Well, hell. That's where the hookup is made for the light-show gauges. I don't know what to say to connect the darn thing.

bad splice or bad wiring can lead to loss. at least you have pinned down the problem. check you wiring...

i dont know how much cleaner the wiring could get, it seemed pretty cut and dry. its just wierd though cause the same exact thing happened to chads buddy too...

[Black02SS]

He was also getting the same code as you. Glad to see that was the problem. Now like smiley said, what is causing you guys to have that problem?

[smiley]

how did you splice it? did you use a crimp connector or solder it, did you have to add any wire (if so - did you use the right guage)? did you have ti all sealed up good to protect from water or heat?

[2000 Tran Zam]

what i did was find the 69 wire, use wire cutters just to strip some of the rubber insulator for the wire, then pulled the insulator apart just enough to wrap the 20 gauge wiring around it. then i used eletrical tape to seal it off an put it back in the wire loom.

[smiley]

i don't know what guage those wires are so i can't comment on that.

but - if you are going to splice like that (wire to wire), you need a drop of solder.

i would suggest you redo that splice. if nothing else - use a quick splice (crimp-on splice), but don't just wrap the wire around the other wire.

[2000 Tran Zam]

the 69 wire is the bank 1 sensor 1 reader for the sensor. its where everyone else plugs it into
