88 VWcabriolet replaced TBI gasket checked every hose need location of air idle control motor and when you get it started up now in warmup its a vary high idle. and wont come down unless you dropcluth?
High idle problem- There is a setscrew at the back of the
throttle body that adjust idle basic idle. there is not really an
idle control motor per say. there is a valve that turns on and lets
air through it and thus adjusting idle. setting idle is kind of a
big job. i would suggest getting a Bentley manual. they are a bit
expensive but A MUST HAVE IF YOU ARE GOING TO FIX YOUR OWN
CAR!!!
other high idle causes-
Vacuum leaks- check all the hoses that come off the intake manifold
to what ever component they go to. I like to spray brake cleaner
over the hoses the idle should smooth out when you hit a leak.
another common problem with 8v's is the auxiliary air regulator it
is behind the intake manifold on the left side. this allows the
engine to idle faster while in its warm up cycle it should get hot
and close up if it does not close it will cause the engine to idle
fast. use a vise grips or something similar to pinch off the hose
that goes into the intake manifold from the air regulator.
You have coolant getting into your oil how?
You have a blown head gasket or a cracked head. STOP driving this car immediately or you will do serious damage to the engine. It will need the gasket replaced and the head checked.
