Hi Mark,Looks like a camshaft sensor failure to me.
Edit - I forgot you have the later 04.
Yes, it would be good to see the graph of rpm vs EBP (and verify it at KOEO).
Thanks Mark,Unplugging the EBP sensor is always a good (free) thing to try on intermittent driveability issues.
I do think that you are on to something w/ injectors #7.
That said. I have not ever seen the intermittent sync.
