Hi everyone - I know a few of you out there have 1.8 litre conversions and I’m hoping you can help.  I bought a 1990 VW Cabriolet with 1.8 as a bit of a favour for a friend thinking that in the long term it might be a nice conversion as well.  Or a great convertible :) 

When it warms up it hesitates.  Almost like the fuel line is clogged.  We have replaced spark plugs, fuel filter, fuel pressure seems ok, compression also ok.  I believe 1.8s are digifant.  

Anybody out there familiar with this issue?

Thanks in advance
