OBD2 shows cylinders 1 & 4 are misfiring. That's only when starting -
after warming up runs smooth. Checking with ohmmeter, both wires are
7.1-7.2 ohms. For comparison, I checked the wire from another cylinder
and
it was 10 ohms.

Gave up on the shade tree troubleshooting. Had it checked at a reliable
mechanic. Compression was 1.2 - 1.3 on all plugs. Head gasket was not
leaking. #1 plug, possibly other, was cracked. Replaced all plugs.
Runs
like a sewing machine. EGR was fine.

So much for T/S by internet and "brand name" shops. Don't know why OBD
gave
bad info.


OBD was correct.

I can see it was right about the #1 and #4 misfires. Why was it correct
about EGR having insuffient exhaust flow?


You did not say anything about EGR codes, only misfiring!
Different thread :-)
