1995 Volkswagen GTI Repair Question
Rough idle (high then low rpms) and surges or lurches when coasting. Hood wont open
Answer
try cleaning the throttle plate on both sides with chokeor fuel injector spray clener. wipe it all out if you cansee if that helps.
Thanks, I will try that,... Not exactly sure where that is, but can figure it out most likely. I finally got the hood to unlatch. I also found that the hose leading into the air filter box is cracked open... could this be part of the problem (even though its not cold outside) I will replace it too.
the throttle plate is at the end of your air duct going to the motor. make sure to hook up air duct before starting car.
'95 Throttle Body should be non-motorized and closes 100% when at
idle (no air past throttle plate).
The Idle Air Valve is used to bypass air around the throttle body
for Idle purposes.
A scan of ECM data via VCDS would be the best way to track down what
is going on (fault codes, fuel trim correction etc).

this type of situation won't appear as a fault code because the computer thinks it's working.
I beg to differ... "Idle Control" faults are common. Idle regulation
faults (Idle to High, Idle too low) will be flagged if there is an
issue.
Even if no code is stored... a scan tool can be of help, by viewing
ECM inputs.

true if a pro does this, not your average person that emails in to get some type of answer.Most of the people don't even have a scanner let alone how to u se one.
I am merely providing info... just like you with your cleaning of
the throttle.
