* Thanks for all the info. Chkd on the Napa gauge. $214. Think I'll try to make one per your plans when I get a few minutes.
* Just took out the right front O2 sensor. Ran the engine briefly with live data connected. That maneuver should have relieved enough excess pressure, if there was any, to smooth out the engine. But still misfiring on right side. I think I've ruled out a plugging cat on the right side. Do I still need the gauge to be certain?
* I've spot chkd injector pulses on right side. Will pick up $30 tool later today to test for spark on the coil-above configuration (should have gotten these tools long ago).
* Now I'm beginning to doubt my work. Maybe the right cam(s) are out of time. Compression is good. Could a small timing error really cause such a misfire?
