Ok its been a while. I got the power back... hehe I?m gonna have to
be careful when driving it now, I don?t need speeding tickets.
My currnet problem now is that it surges badly, not just at idle
either. I can feel the engine surge while under load, when i down
shift, and when it idles. When idling it surges so bad that it causes
the check engine light to flicker on and off. a few times the surging
was bad enough while normal driving that the knock sensor kicked in
and dropped the rpms and power way down.
On the throtle body there is that adjustment screw that is supposed to
be pluged (the one you are not supposed to adjust) well the previous
owners have the plug removed and i think that the screw has been
adjusted. any thougts?
also its mid summer here, hot as hell out and the temp gague doesnt
really get up to normal while driving, it hovers around the colder
side, unless idling for long periods. is the gague screwed, the
themostate, or the sensor bad? I was under the impression that VW?s
generally run hot.
