Idle problems on my 85 GTI
I just bought an 85 GTI on saturday. While driving home 80 miles
whenever I stopped or idled the car the idle speed was at 2000 rpm. Yesterday the same thing even at a cold start. This morning when I got in the car and drove in stop and go traffic the idle was right at 950 rpms. The rpms did surge up and down a little but not enough to cause alarm. What could cause my idle problem? Is there a vaccume leak? Any suggestions are welcome. |
Sounds like a vaccume leak , check the aux air vavle and the hose connected
to it... also check your aux air vale wire, make sure power is coming from there.. you can also squeez the hose for it and see if it drops. -Lee "Petey" > wrote in message oups.com... >I just bought an 85 GTI on saturday.

A bad ground can do strange things. |
I've had this problem with 2 of my VWs in the past. More than likely
it is as simple as on my cars. More than likely one of the butterflys on the Throttle body is not closing all the way. Next time you drive around and it's idling at 2000rpm pop the hood and just push a little on linkages towards the closed postion. More than likely the RPM will drop if you push it closed a little. You can't tell just by looking. If that's the problem try cleaning them up with some Carb Cleaner. If that don't work just get a new T-Body off of another car. |
