Alright. About a month ago my 1998 ram 1500 popped up with a p0303 code. I got this code a couple years ago, cleared it and it never came back until a month ago. At first I thought it would be on the ignition side of things. Replaced spark plugs, wires, distributer cap, rotor and coil wire. They all looked like garbage and i thought it would fix it. Cleared the code and it came back. I thought it may be a fuel injector so I switched injector #3 with #1. The code went away for 2 days then came back still saying cyl#3. The truck runs fine. Only thing i have noticed is at idle it almost stalls and then revs back up. It’s completely random no pattern to it. Im about to run a can of seafoam through her vacuum system this weekend. But does Any one have any ideas for me?
