Another Little issue

JB 06 KING RANCH · #1 Mon, July 19th, 2010, 11:52 PM

I seem to have that problem too but its not any giving time. It has a miss feel to it. It will come and then it goes away. Just this last time it happened was on open interstate, I was driving for about 10 miles of on and off the gas passing, when I stepped on the gas to pass is started to shutter or miss, it did it about a mile while I had my foot on the gas. It ened up being fine after that and no problem since, but I know it will happen again.

Ya my first thought was that it was a spark issue but after i thought about it, doesn't level 2 and 3 require more fuel?...
If the fuel filter is clogged then it might not get the fuel it needs.

My other question about the maintenance tips is: do i have to have a dealership or mechanic check the plugs and coil packs?
How do i clean the MAF sensor and the throttle body?
And how do i know if the fuel driver control module is working properly or do i have a tech check this out?

Thanks for the input. I really would like to get this straightened out because i have it turned back to stock and man what a slug compared to even level 2.

Since you have an 08 with less than 20,000 miles, I cannot believe it would be the MAF or throttle body. The fuel driver module is in front of your spare tire on a crossmember and you can see it if you lower the tire. Again, I would not suspect a problem there in an 08 unless you drive a lot on "salted" roads. If you do have a problem, it will have a "corroded" look and may appear to be distorted. If that is the case - replace it right now.

Again, a clogged fuel filter doesn't seem likely in 20K miles unless you fill up at stations where there's a lot of sediment in the gas.

Plugs & COPs? Maybe, but I doubt it.

Does the problem occur at all with the stock tune and, did the truck ever throw any codes? Possibly, there's a PCM flash update that would fix this and since you don't have custom tunes, it wouldn't hurt to ask your dealer about it.

I don''t see why Edge is referring you to PHP - they should only do that if you have a Gryphon.

Put it back to stock and haul it to a dealer, its still under warranty.
Drive it 50-100 miles to get rid of the p1000 code before taking it in.
BTW
What's your hex code?

I experience the same symptoms in my truck and only on #2 tune. It doesn't do it on tune 1 and 3. Since 2 is for towing, I just decided not to use it unless I'm towing, which isn't too often. And when running on #2, and the truck misses, I usually pull over immediately, turn off the truck and it stops the rough running for another two weeks or so.
