Ok if u get on my truck hard from a dead stop. It will miss terribley. And sounds like it is back firing. But if u lift up and ease into the throttle it is fine. could this b my coil. (i have the wonderful accel) I doubt its my injectors cause it just developed this problem.

 

I would start at checking the plugs and the wires, then cap and rotor.....also do you have any codes

 

because it's an accel, that would be my first place to look..

 

Maybe the tps not reading correctly?

 

Sorry for double post stupid phone froze

 

Its either air, fuel, or spark.

Verify fuel pressure at the rail at 49psi.

Check wires for loss of signal whilend checking ohms.
Visually inspect plugs, cap and rotor.

Swap coil for a known good one,

Then start looking at sensors.

 

No codes cap rotor wires all look good. Guess stock coil is going back on tonight
