2001 jeep wrangler sport 4.0
Codes p0300,p0303,p0304 finally just came up after two weeks with a flashing cel and stalling/ bucking. Exhaust is fine, and i replaced the plugs, coil pack, fixed the vacuum leaks, and ran seafoam through both ways. The seafoam made it idle little lower though. I've tried looking it up on Google and i can't find a constant solution. Any help or knowledge could help. I just don't want to go changing 100 different things for a simple solution if it has one.
