I own a 2001 Dodge Ram 1500 2wd. I have replaced basically every sensor on the motor, put new plugs, wires, rotary button, distributor cap, fluid change, cleaned intake, replaced gaskets, and still cannot figure out what is wrong, at idle, it sounds track ready as if it has a stage 4 cam, but the motor is stock. When driving it is weak and pops and backfires from the right side of the motor. Anybody know what else it could be

 

What motor is in the truck? If its a 5.2 or a 5.9, do you have any oil in the bottom of the intake? The noise you're hearing may be a blown exhaust gasket on the right side. Have you done a compression test on the motor? Is there a check engine light on? If so, what are the codes?

 

What plugs? Recheck your firing order.

 

I did check, I replaced the gasket and it is fine now, we pressure tested the fuel pump and that seemed to be the problem it was only getting about less than 10 psi when it needed around 40-50 . It is all resolved now

 

Thanks for the feedback as to what solved your issues.
