New Truck is Missing
Hey guys as most of you know i recently bought a 2000 Crewcab Lariat 209xxx miles. When i brought it home the WIF light was on. I checked and changed fuel filter, and drained the fuel bowl. It had a slight miss in it when i got it. But after pouring the sea foam in the WIF light went out.
However the miss is still there. Cory hooked it up on AE, all my numbers were good except the ICP pressures were fluctuating. EVerytime the numbers would fall the miss was more noticeable. I swapped the ICP sensor from my truck to hers and it didnt change anything. While driving it at half throttle, you cant feel it, when i let off a lil bit you can feel it again. Does anyone have any suggestions or thoughts of possible ways to fix it?!?!?!?!

What all did you check with AE? Contribution test or rotational velocity OK?

Hmmm...I'm sure if he saw something amiss he would have said something. Have you had a chance to pull the VCs and torque check the injectors and valvetrain? Also might want to pull the oil filler cap and see what comes out of there while running. What the heck, swap out your CPS too while you're farting around since it is so easy to do.
Oh, and make sure that goofy tin nut is tight on the IPR which you may consider swapping out since you have two of those now.

Mike thank you for the suggestions, I havent had a lot of time to check much on it yet. My truck is back in the tranny shop for an annoying lil ship that has recently reared its ugly lil head, its still under warranty and i want it to be taken care of first before i start tearing into hers.
