Guys,

Have anyone ever had this issue? I'm all stock, throttle body removed and clean, and spark plugs replaced. What else I'm I missing?

Thanks

Is your check engine light on? Mine was doing the same thing and had the CEL on, the code was for a leak in the evap system. I changed the solenoid beside the drivers side of the intake and the canister on the side of the fuel tank, both easy jobs as long as you are careful with the clips. Cleared the code and it is like a new truck. A vacuum leak like that will lean out the AFR and the truck will feel like a turd, especially at low rpm.

Clean MAF and replace plugs, ohm and inspect wires.

Is this the normal drive by wire hesitation, hit the gas and theirs a second or two delay before you feel a response.

My truck was real bad with that. I did boltons and tune it was night and day difference.
