Shop has run a hot and cold smoke vac test and found nothing.
Been there now 5 weeks. :|
He thinks its electrical and is waiting for the right block of time to be available to test it.
Selectron/Anyone - Do you think I ruined the O2 sensors by soaking them overnight in electrical parts cleaner? Did this a while back. Also, what do you think are the chances of the O2 sensors still being good past an engine overheating and known glowing red cat on the rear bank?
I don't understand why the smoke test didn't show anything though. I'm wondering if its possible water could get through and not smoke or if the whole crankcase wasn't pressurized with the smoke maybe the smoke didn't reach the right area or enough pressure to force out.
Is it possible the heads aren't grounded to the block and maybe the water momentarily grounded the head(s) to the block causing it to run better and then run misfiring?
