Last time a tune-up was done? Or even the gap on the plugs checked?
Mk2 golf w aba motor and today while driving home when I'd pull up to a light or come to a stop, after pressing the clutch the rpm's shoot down to almost stalling (twice it stalled) then shoots back up to normal. I searched and found a lot on the icv.
but before i get into that another slight problem is earlier i was driving and while staying at a steady speed, not accelerating, it seemed to "bog" down slightly, or sputter almost but hardly noticeable.
I feel like this could also be a vacuum leak, will look more into this weekend. It seems more of an inconvenience than a major problem but I need to figure it out nonetheless.
Cleaned throttle body and ICV with carb cleaner and sprayed it down with wd-40 and it made no difference with how it idles, haven't driven it yet. I sprayed down all the air stuff with carb cleaner looking for any vacuum leaks and no change in idle either.
Any other ideas of what it could be? Again, the rpms drop super low (under 10 grand) when I push the clutch and occasionally it drops so low it stalls. Also while accelerating and shifting up it'll hold bog out slightly then jump back to normal rpm range.
