lol telling us about an o2 code should of been in the first post..that's a biggie and could explain it all

Also you said built 5.0...what do you consider built

Nate3.8 · January 4th, 2012, 02:43 PM

no i had the h pipe then switched to x pipe but that was months back this issue started a little over a week ago. the plugs are fine i checked them sunday. and the O2 code is po1131 it has been on for a while before this issue started. and no its not dumping to much fuel its like its not getting enough. if i hold the pedal about a 1/4 of the way down it will pull ok around 2000-2400 rpm over that it boggs down.

i worked for a machine shop for 9 year doing machine work on motors. i now do CNC work. i built the 5.0 motor had heads, cam, and bottom end work done. was a 331 stoker.

Nate3.8 · January 4th, 2012, 02:58 PM

Nate3.8 · January 4th, 2012, 03:05 PM

but yeah the car ran fine before and i already had all the exhaust on it and i have done nothing to it before this started. i have even replaced all the vacumm line. like i said the o2 light was on for a while before this started. i do need to replace it but i need to get it back to normal first.

Nate3.8 · January 4th, 2012, 03:06 PM

i have seen alot of people on these forums with similar problems and people have had good input but i have not seen them say what the issue was when they got it fixed.

iPAPKE · January 4th, 2012, 03:43 PM

Plugs/wires/coil pack.

Nate3.8 · January 4th, 2012, 04:10 PM

have replaced coil and plugs. wires i am replacing this weekend. i ran across something a few mins ago. this all started when we had a huge rain storm a little over a weeks ago. i noticed today taht inside my MAF housing there was whit spots like old water spots. if water got in side that housing could it have ruined that MAF sensor because i used the MAf cleaner and that didnt help it i got a new code a few min ago po174.

6ER THEN I 8ER! · January 4th, 2012, 04:17 PM

yeah you can short out the sensor..

Nate3.8 · January 4th, 2012, 04:25 PM

i think that is the issue cause that code is making it show running lean now. and i noticed some moisture in the air box. when i ran my otc data stream while i was driving when i floor it the MAF g/p keep jumping from up and down.

xtreme 2 · January 4th, 2012, 04:36 PM

yea as the rpms climb so should the maf sensor. It's shouldn't go down until you let off.

MAF would definitely cause that too. Time for a swap out.

Nate3.8 · January 4th, 2012, 05:00 PM

yep 71$ to pick one up takes a day for them to get it.
