Hey all, how's it going.
I've just recently picked up a series 2 R33 GTS25T, and I've got a bit of a weird hunting problem with it.
Basic symptom is the following: When moving the car just a little bit, be it in reverse or 1st gear, upon clutching in and braking, the revs will begin to hunt, going between 0 to 1500rpm, not necessarily that whole scale, eg it could go between 700 and 1500, or could go between 0 to 800, etc etc.
Perfect example of this would be in the drive through getting food at suchandsuch fast food place, when moving forward in line, so clutch in, first gear, bit of revs, clutch out, move forward the car length, clutch in before braking to a stop, and the revs will begin to hunt, or worse, it just plain stalls.. Will do this for about 30 seconds, and then come good. Giving the pedal a rev doesn't help this at all, it will continue to hunt after the throttle is closed.
Another example will be turning into a car park, full lock, clutch in and brake, engine will stall.
Idle is set at 750rpm. Is this too low?
Can anyone give any ideas for a solution?
Things that have been done:
CAS replaced, timing set correctly as per timing label on the bonnet (something like +15 btdc at 700rpm or whatever it is, it's been done as per the label).
Things that I will give a go and see what happens:
Clean the AFM with some contact cleaner (won't take it apart and touch the element, will just use the contact cleaner through the mesh or whatever).
If the contact cleaner doesn't fix the problem, I'll replace the AFM with a spare one that the workshop has, which they've said I can do, as I bought the car from them, free of charge.
Replace the plugs (probably should do it anyway, compliance place didn't do it as far as I can tell), and give it some good oil.
Apart from the above, intermittant problem, I've enjoyed my almost 3 weeks of Skyline ownership, such a nice car to have after having owned a fairly modified suspension wise S13 that was an absolute pig to drive on the road with its aggressive 2 way diff and all the fancy arms.
Cheers all,
