Okay so still having misfiring issues with out check engine light. 2 1/2 years of this. Ive been reading up on stuff and something that caught my attention was reading about the throttle body snapping shut. Let me explain.
When im at higher speeds and I let of the gas the truck instantly starts to slow down and back fire like if it were a manual and down shifted. It just doesn't seem like it wants to coast anymore and I have noticed mpg drop due to this.
I have supermods ptb and tune, cai, second cat and straight pipe.
Anyone else running similar mods have misfire issues?
Valves burning up from straight pipe? Throttle body problems? Etc..?
I have to much time and frustration into this problem that wont go away. And I cant afford to pay anymore waiting while the dealer tries to "replicate" the problem while they have my truck for a week.
Any help would be awesome and I will send virtual highfives and hugs to whom ever chimes in with helpful info.
Thank you,
Manny
