07 3.0 rough idle, no cel.
 
07 3.0 rough idle. No cel. 208k

I originally had a flashing cel. Through trying to diagnose myself, I did a tune up, replaced my coil pack, and replaced all fuel injectors (2 of them ohm'd bad). Long story short, all that did not solve the problem. I took it to the dealer and they informed me I had 2 cylinder misfires due to bad valves and both my cats were toast.

I have installed 2 remanufactured heads, and 2 new cats.

Now I have a rough idle with no check engine light.

Torch the truck for insurance money?

Lol, please help..

Compression test is in order, make sure it's done right (ie, engine warm, ALL spark plugs removed, throttle fully open and good battery charge). This, assuming there are no vac leaks and all hoses were put back where they belong.

Have you checked the plugs and wires? Maybe even the fuel filter?
