Are they both mopar sensors now?
|
Neither are, it’s developed a miss when it’s cold now, and hesitates
|
You really want mopar sensors in there....... the aftermarket fellers just don't work as good.
|
After it runs about 6 or 7 minutes the miss disappears and runs great, so I don’t think it’s related to the sensors to be honest
|
Have you checked fuel pressure? Wonder if it is a bit low, and when the truck goes into closed loop, the O2 sensors compensate?
|
Well it started messing up real bad today after sitting for a few hours, I didn’t let it warm up just jumped in and went and it was terrible, so I pulled over, used a code reader(p1391) same as before, cleared the codes and it ran fine so I would rule out fuel pressure
|
I got some freeze frame data, the short term fuel was at 0 and long term fuel was at -3.1 when I get code, I accidentally erased the reader so now I have wait till it happens again
From what I’ve read, total of both should be around 10% Engine load was 0 and rpm around 796 speed was 0 My scanner only does freeze frame at time of the cel |
Hhhmmmm...... Are you still getting the 1391 code?
