Running really rough I started my truck a few days ago to go to work and it was running really rough .also noticed that the A/f Guage wasn't reading anything ??
So i just got the time to pull the plugs and found that all the the plugs on the driver side look like **** and have lots of carbon on them with little yellow whitish tips .the Plugs on the other passenger side look ok still have yellow tips to them and a little carbon nowhere near as much as the drivers side
I also got a cylider missfire code when we scanned it ?
any ideas on what's going on with the truck
the plugs are pretty NGK tr6's new maybe 3500 miles on them
Also What fuel presure should i be running at ?
the techs at ATI told me to run it at 60 psi
is that too much fuel maybe for idle ?
thanks
Jim

Re: Running really rough 60 psi is fine. Any codes? goofy/non-operational gauges signs of pcm problems . (all gauges pcm controlled) grounds also can cause stange/intermittant problems.
