So I've been riding a lot about this and I cant find a satisfying answer.
Watch the video.
The car is already warm. when you rev it the engine revs up and down normally but hangs at abour 1200 rpms for a WHILE and then drops down to 800 (normal) is that normal? This is my first used zx3
Also when I am driving, lets say I want to come to a complete stop so I let off the throttle for a while watch the engine rev down a few hundred rpms and then when I press the clutch to shift out of gear it revs up on its own.. about 200-400 rpms.
Also when I let off the throttle to use the engine to slow down it seems to hang at 2000 rpms for a loooong time.
Are this issues normal on a ZX3 ???? (2000 with 90k miles)
If something is wrong, any idea what? I tried finding vacuum leaks but no luck and I used seafoam to see if that helps and nothing either. Cleaned the Throttle body too (which was nasty).
