All,
i'm having problems with the air con in my r32 rb20det.
Problem:
Whenever i turn the a.c. on at idle, the revs suddenly drop to ~200rpm and comes back to idle. If I blip the throttle ,the revs will go up and then come down close to stalling, then settle again. Makes it hard to drive in traffic.
Details:
rb20 with a microtech lt12s.
Cleaned aac, even tried a different one.
checked grounds and made a grounding kit, no difference.
This problem slowly appeared and I can't think why it has.
Any ideas?
