Sporadically idling very rough have changed coil pack, plugs, plug wires, o2 sensors both of them, knock sensor, air flow sensor, PVC valve, about to check vacuum and compression. Have reset computer numerous times and gets better for a little while after but then throws another code and gets worse.

Are you only getting a P0300? When checking for vacuum leaks, make sure you check the EGR as well and around the intake manifold and throttle body.

Hey guys look I'm not your average shade tree mechanic when my father was alive he was an ASE certified mechanic and I myself have built 3 hot rods. I had check the vacuum lines the computer board itself along with changing almost every sensor in the van after the compression test came back hundred twenty pounds I knew there was a bigger issue so I put them up of the intake and there she was some genius that designed this van tied the wiring harness for the fuel injectors right to the side of the rear head and you can't see it, melted all the wires together. I fixed it and I wish I woulda looked at that $800 ago because that's what I spent changing all the sensors
