hey guys I am getting these codes but they will come and go they wont stay. so what is going on is I leave somewhere like a parking lot or something after I have came in and shut my truck off and the leave if I get on the throttle hard right away the truck will loose power and stall out and I have to pull over and shut the key off and sit for a little bit and then it will start and the check engine light will be on. then when I read the codes with my edge these are the two codes I get. if I clear them everything is ok and the truck runs fine until I do the same thing over again. I have read some post on these codes and have not found anyone having the same problem as me. I have found people having similar problems but mine will come and go. I can either clear the codes with the edge or just wait and the light goes off itself after a little bit of time. I have read that it can be as simple as a wire shorting or being pinch, bad connections to the injectors, bad connection to the edge and or bad edge box, or a bad injector. so after reading this long post of mine what are your guys input on all this?

 

Start chasing wires...

 

yea that's what I am hoping it is or a dirty or messed up connection could that also be a reason why it seems my fuel mileage seems low? has anyone had any problem like this who is running the edge and did it have anything to do with it?

 

When I first installed my Edge purchased used, I got the p2146 code and truck was not running on all cylinders. Ends up the harness from the edge to injectors was the cause. Unhooked the injector harness and have been running that way for a year with no ill effects. I had cleaned the connections, etc to no avail/ shrug.

edit, need to upgrade signature, I am running an 03 as well.

 

well like I said before the codes only come up when I try to get on the throttle hard when leaving like a parking lot as a matter a fact it just happened again today but once I start the truck back up it runs perfectly fine no power loss or anything but I have the codes and they will go away like a day later or I clear them. so I am hoping that's a shorting wire or something like that. I am also leaning towards that could be one of the causes of low fuel mileage plus its been cold here this winter so that also has something to do with the mileage. I have not yet checked wiring probably will do that this weekend and hopefully find something and not find out its a bad injector. although I would think if it was an injector it wouldn't run right at all
