16 Ram Outdoorsman 1500 (3.6) Code P0303

[Steveoburrito]

Hi all.

A few months ago code P0303 popped up on my scanner, followed by a rough idle. I changed spark plugs, coil packs, and ran fuel injector cleaner (sea foam) through it. All rough idling has stopped. But code p0303 seems to come and go, on and off. Should I change the injector? Is there a sensor that’s possibly bad? All help is greatly appreciated!

Do you have a multimeter? If so, check for this...

I figured the injector was probably the next best bet. Thanks a lot!
