So had a nice visit from Larry and his 77 NYB today. He was having issues with low speed drive ability and rough idle/miss stopped in drive. So i checked the usual timing/vacuum etc adjusted the idle speed up a bit from 675 to 770rpm in park blah blah blah. So here is what I found on test driving it
Part throttle miss
Rough idle in drive maintains 650rpm
Smooth idle in park
Good snap throttle and return to idle
Downshifts properly
No pinging under load
No get up and go
Specs
77 440 ELB car with non functional ATCII
Recent ELB delete with new dizzy orange box coil alternator voltage regulator ballast
Plug wires done 2000kms ago by PO
Manifold vacuum at 770 15”
Timing 15 degrees
Original ELB Thermobog with idle stop solenoid removed
I didn’t check all in timing
So yes the TQ needs replacing with a non ELB unit as it may be leaning out or accellerator pump worn running 91 octane non ethanol gas
Plug wires are unknown so thinking of starting there
What say you collective?
