Well, rechecked the grounds. Found the one behind the EGR valve loose, and snugged up the one beside the CPS and the one at the back of the block near the coil. No more solenoid codes, but I'm not holding out much hope til the engine cools down again and I do a cold start. Still missing though.
Got it to happen in the driveway. Loaded up the engine in reverse, when easing the throttle down there was a definite hard miss and 1&4 would count it. Only when throttling down though, not full throttle.
