your idea seems reasonable, such a drastic change in AFR
given its a dyno day and the sensor is moved around a lot, it might be a bit whacko or something
for such a dramatic change in AFR, i would have expected wonky power curve, detonation
its probably easier to fit the correct coilpacks and sell your old S2 stuff
it would be easy to sell the S2 stuff and coilpacks are a common failure in the skyline, so your best to fix it properly and be done with it
just unplug the AFM and see if it idles
the engine will run with no AFM and should idle OK, but it wont drive very well and will rev cap at 2500RPM
if the AFM is the culprit when you unplug it, it should run to normal idle
if the AFM is NOT the culprit when you unplug it, the same problem will be present and it will stall
I've been on the job for over 20 years, and I fail to see what fishing bricks from the bottom of a pool has got to do with bank robbery. And on top of that, they got me babysitting some quarterback punk, named Johnny Unitas or something.
if you dont know what you are doing lower RPM is better
going off the line at 3500rpm will just result in wheelspin or hopeless launches
start off slow and around 1500rpm and learn how to side step and get it off the line
without all out power / wheelspin or bog the dog
also check tyre pressure
this is crucial to be able to launch and get grip
for drag run 20psi in the rears
suspension work is also important for traction off the line
do you have std clutch? can you afford to replace it?
launching / drags will fty the std clutch, specially with 265s
dont even bother
if its cracked, it will be split and dead obvious
just unplug each hose carefully (the vac ones) and visuaually inspect
usually they fray and split apart where its been cut
if they are, thats good
was hoping they were std globe and not some uber spec light assembly in one piece
will check it out when i care and can be bothered
dont drive my car to work so not urgent urgent
vac leak, check all the vac lines for any splits or cracks in the rubber
take each end off and visually check it all around where it is cut
the old rubber vac lines are notorious for leaking / splitting when cut and are the old rubber factory items / vac lines
