Am having trouble finding the code p8=02
This comes up with others on my 2002 screw 5.4 using a superchips tuner.
Truck has been brutal on fuel and now to top it off has a bad miss after running though some powder snow. The other codes showing up are p1000, p1151, p0174, p0306, p0307, p0316. No trouble finding these, can anyone help with the first one?

So far the plan is to change all spark plugs, air filter, fuel filter, 02 sensors, clean MAF, and have a couple new coils on hand in case of need. Any other suggestions?

 

The p8=02 is probably something you will have to go to the Superchips library to find out.

P1000 is nothing to worry about, it just hasn't completed the required drive cycles since it was last cleared.

The 1151 and 174 could be related to each other. Lack of switching in the down stream O2 and lean bank 2. Could be an exhaust leak or vac leak.

306/307/316 are misfires in the respective cylinders (6&7) and 316 is multiple random I believe.

All things considered it might be a fuel delivery issue, but that's my guess. Some one smarter than me should chime in shortly.

Good luck

 

Does it still do it when the truck is set to stock?

I'd hope it is if you are getting a p1000.
