2003 V10 Acting Up

I have a 2003 V10 F250 with a little under 8,000 miles on it. I have the Banks PowerPack with the Ottomind chip.

Lately (since it has gotten warmer outside) the engine knocks/slaps/pings (not sure which) any time I accelerate, but not when it is idling or coasting. Also, sometimes when I first start it the engine will diesel or miss very bad. It gets to the point for about 1/2mile that if I floor the truck it will not accelerate, it will almost die.

I have tried taking out the Ottomind chip and sent it in to Banks to be inspected. That doesn't seem to have been the problem. Any other ideas?

There are various, numerous, and sundry things that can be wrong.

Are you skeerd to take it in under warranty?

They can do wonders with that equipment…

I hate taking it to the dealership because of the lift and the Banks kit. Also, they always take about a week to be able to see it and then say that the problem is "normal". At least that was my experience with an out of balance driveshaft that was causing a vibration.

On something like this, is there a way that they would end up charging me to look at it if they felt it was because of the modifications?

Check your spark plugs maybe. I had those exact symptoms on a 97 4.6, checked the plugs and one was almost out and ready to launch. Might be worth a quick look.

If you do take it in take out the chip! I would clean the MAS wire in the intake. It could have got airfilter oil on it.

Sounds like you need to find a different dealer. A week is insane. Had a Ford dealer keep one of our ambulances(2000 E350 w/7.3) for 6 weeks and never found what was wrong. Took it to a shop that just works on ambulances and they found the problem in 20min. no joke. How does the Banks sound? I plan on getting a Banks in about six months but want to hear it first. Any chance of posting a sound clip?

I took it in yesterday and dealt with a different guy this time. He was very helpful and we figured out that it was a loose header bolt. I had never heard an exhaust leak sound like that, but I guess so.
