Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Stumbling then stall cold and warm start.



Question, when I unplug the maf sensor and TRY to drive it, it stalls and runs even worst, but mainly stalls. Since the map and maf works hand in hand does this mean I have a map problem?
 
they dont run great with the maf un plugged. but if it runs better unplugged the maf is bad for sure. most of the time you get a code for the maf if its the issue.
 


Yeah, I figured if it didn't want to at least run without it then it had to be one of the other sensors
 
Thought it may have been my old pcm but Since I keep getting codes p0133 and p0134 with my new afs109 I'm going to purchase another so what's the difference between the afs109 and 2131331
 
So does this looks like the right schematic for the 2 o2 sensors on a l67?

I already bought another o2 sensor if it doesn't work I'm going to have to do some hard wiring
 
Well to help anyone with the same symptoms, yes it was my front o2 sensor. I read the instructions that came with my new o2 and it states do not drop. So ass I gathered my thoughts, my previous o2 sensor which was new had been sitting in my trunk along with my 2 15 inch sub's. So that o2 took a beaten for many months.
