(Thread Starter) |   Not Ranked : 0 score  took the intake manifold off for cleaning. EGR was definitely clogged. but it was clogged in the intake manifold in the elbow right were the pipe comes in and it bends up in the cast manifold into the intake plenum. haven't put it back together yet but it looks like that was it. it was so clogged I couldn't pass a wire through it. I kept poking it and spraying b12 on it till it gave and drained b12. then i kept cleaning more. It still needs more work but it is much better than it was. miss fire is back though. I've done some upgrades and it seems to have made the misfire more pronounced and dangerous. I've melted 2 spark plugs.  I'm pretty sure it is a fuel injector problem. I'm looking into it now that the intake is off. The injectors looked a really dirty. and I have a HPFP with good pressure that also points to the next point of fail which is the injectors. the metal pipe was fine.
