<SOLVED> Stuttering

[daveismissing]

Thanks for the links - sometimes its the "remembering" that the problem.
inner loop and outer loop....

remember that fuel FLOW changes by the square root of (new pressure/oldpressure) so a five psi change is not a massive change.

Excellent - to the heart of the matter

Gents, I have a log from last weekend have a look and see what you think...

to add to what Eric told you, check for even clearances on the crank sensor as well as no wobble in the damper.

If that does not fix it, try wiggling the the PL connector around a bit to see if that cleans up the contact and gets rid of the problem

Sufficient road time now:
I think we can say this is solved- root cause  crank sensor/connection.

Post-mortem review suggests more so the corroded connection, had the sensor survived the arduous
removal we may have had opportunity to verify. The symptom's disappearance for a few days
when the cam cap was changed and harness being pulled around plus the condition of the connections
kinda fits.

My thanks to ALL for the support.

Glad it is good now...I hate the problems I fixed without being 100% sure I knew why it got fixed...happen ed many a time, tho

Update:
this problem came back with a vengance  late in the year and the car just got put away, too pissed to post about it. 

Following the original hypothesis I rewired the crank sens back to the CCCI- same
Replaced the CCCI and pack with a type II I had-same
 
I then swapped the Cam cap for a third new one and the TPS-
from the moment I started the car I could feel it was different( ie "right")
goes like stink

So its gotta be one of the two or the wiring to the cam sensor
And AJ has a 33.3% percent chance to say "I told you so"

Dave...put one of those many glasses you have hanging around your neck on and check the wires that go into the weather pack TPS connector. You may find one that has a slight break in it. Had the same stuttering problem with Dans car a while back. Drove us nuts. Swapped every electrical part on the car before we stumbled on it.

Hey- I'm trifocalized now!
Definitely worth noting , tho my car has so little fixed/modded that I want to believe the harness is fine.

Sure could use another 4 inches of slack in the harness at the CCCI.
I'm not sized for engine sprawling.
