Problems with '89 VW Fox

Home  \  Repairs & Maintenance  \  Problems with '89 VW Fox

Please help my Fox is having a problem with idling when it is first started. It will idle @ about 250rpm and bounce from about 100 to 500 rpm. After some time it usually levels off in the normal Idle range of 900 to 1100 rpm. I belive that there is an air leak at the bottom of the fuel injection system but i am not entirely sure that it is the problem. The fox has a cis-e fuel injection system and I believe a 1.8L inline 4-cylindar.

Any thoughts, ideas, complaints, or whatever. Please Place them here.

Thanks ahead of time. :guns: :banghead:

LOL....Great combination of smillies there :thumbs:

Does is start off idleing at about 250rpm? or does if climb very high before it idles rough? The reasonn I ask, is that an air leak would usually cause things to happen in that order...

That is what happens, I did not think of that until you metioned it. :doh:

That's probably your problem then, check all the vacuum pipes that you can find, if you can feel air over any of them, cover the hole (if you can) with your fingers, if it improves you've found ya culprit! :thumbs:
