I've resurrected an '87 GN!
I've done all the Spring Cleaning except for Differential fluid (for this weekend).
MODS listed in Sig. Plugs CR42TS gaped a tight .35. Fuel pressure is 43 line off, 40 line on.
The car feels like about a 14 second car or so. However, it hesitates/cuts out and sounds like a backfire or two through the intake at part throttle or when I floor it for the first 2-3 seconds or so then it takes off. making about 14-15 lbs of boost.
Car shifts at about 4700 into 3rd. Supposed to be 5200? Need springs?
Idle:
02 - 400-600 (all over)
AF - 4
LB - 27-28
INT - 128
BL - 135
RPM -875-900
TPS - .44
IAC - 0 it was 19 before re-adjusting the TPS. I'll fiddle with it again.
CC-20-250 Starts at 20 and goes up in multiples of 20 or so until 250 then starts again at about 20. repeat.
Full throttle 3rd gear runs.
02 - 782
kr - 0 Sometimes got .5 or so with the pops through the intake
AF - 190
LB 255
INT - 128
BL - 121
TPS - 4.60
IAC - 72
CC - 189
Thanks for any help!
