Title: rich after new pump and filter?
Post by: jamie16v on 18 May 2013, 20:27

is it normal to be suddenly running rich on low idle after changing to high pressure fuel pump and changing fuel filter or could this be another issue. codes have been scanned and none came up.
99 mk4 AGU by the way.

scanning codes is like ... about the right thing but just not right in there....

what do measuring blocks say?
how do you know its running rich?

havent put it on vcds yet, the battery in my lappy is sh!t. but i have had it on an exhaust gas analasys machine.
the fuelling is going to be all over the place at the moment anyway after fitting a k04 turbo, but i wouldnt have thought that it would affect idle and if anything would make it lean?..
