Re: [T3] pressures (long)

Done, done, done, done, done, and done, except for compression check.
(coming up soon) also checked dwell(sort of) and advance.(35deg)  Spark
looks okay but pitting points say coil could be a problem(?)

Checked, but can't remember exact voltage, will check again.

Done, and replaced, all were identical, looked fine.

Done. one still barely sort of leaks some of the time. Still working on

'68, Done, works great, unless the problem is in the computer itself

No I do not have one.

Please do continue.

Another problem to really throw you off is that when the engine is cold it
runs very uneven: sounds like one cylinder is having problems but I can't
for the life of me figure out which one.  And yet the plugs are identical.
I have unplugged injecters one at a time many times but I can't quite get it
with just my ears. It happens at all RPM's while cold.  My neighbor is a big
VW nut and mechanic and I have him stumped as well, even after he listened
to it himself.  This unevenness makes it a pain to drive before it is
warmed up, then it is smooth as silk. It is also smooth for about 2 seconds
immidiately after starting, which would point to... mixture? injectors?

While meticulously checking the FI harness (recorded all ohms) I discovered
that injector wires 2 & 3 were switched, correcting this made no difference.
I also inspected the FI points, they looked fine, fired right on time, and
both dwelled the same.(160 and 165 deg about, with a protractor) don't
laugh, I'm desperate
Sorry to be so long, please help.
