I have a 2004 dodge grand caravan 3.3L v6. My van feels like it's missing at idle. Or a rough idle. getting code p0300 p0306. Changed spark plugs/wires/coil/crank position sensor. Cleaned fuel injectors cleaned throttle body and all intake sensors. Cleared codes with OBD2 tool. They came back as before and engine still misses at idle. Any help would be appreciated thank you.
Have a compression test done on cylinder 6 and the rest of the cylinders. See if you have any vacuum leaks and change the air and fuel filters. Check the fuel pressure as well
If your injectors are bad no cleaning is going to fix the problem
I would swap another injector w #6 and see if the problem moves to a different cylinder
