Hey guys...Before I completed my tune up (Magnecors, plugs, seafoam, new head gaskets and heads reworked) I had a misfire in cylinder 5. The heads checked out ok and I replaced the head gaskets (losingcoolant through the exhaust) and everything was running great for about a month. Now my CEL came on with a P0305 and P1319...Am I looking at a fuel injector issue? That is the only thing left that has not been changed except for the coil but I guess there would be two cylinders misfiring if the coil was bad. If it was a fuel pump issue seems like other cylinders would be affected as well.

I just find it odd that after all of that the same cylinder is misfiring again. Please help.

Did you ever get to the bottom of this. I have the same problem except in cylinder 1. Re-built the engine and still get the same codes. Just the 0301 and 1319. I don't know where else to look.
