Hello all, I am mind boggled now. My Ram keeps kicking up a 0305 and sometimes another 0306 or right now 0307. I have just done an compression check on 3,5,7 and the compression ranged from 160 to 170. I have replaced the injectors in 5 and 6, the coil pack in 5 and the plugs in all 8. I have tugged on all the injector and coil pack wires and all seem tight and in good shape. I started the engine and sprayed brake cleaner on all rubber hoses to find a vaccuum leak and nothing.

I took it for a test drive and it seems normal, but the skip always comes back. oh and at 50ish if you hold pedal it feels like engine bucks. I am stumped can someone give me another idea to check. Thanks..
