Lately I have had problems when I am starting up my car.. I have to let it idle for a few mintues before driving, and even then it sometimes stalls. It also seems to take forever to build up boost.
Oh, its a 98 1.8T A4 Stage 3 with the usual supporting mods

what do your o2 sensor #'s look like

Audone

I will take a look at them tonight...

Audi2ptzero

also check maf readings.

PD Performance

That will give you an idea of where to look. If its way + in the first field its at idle so that means a vacum leak. If its + in the second field then its most likely a MAF..

The slow to build boost could be from the bad maf on a cable throttle 1.8t, or a boost leak, however a boost leak usually would be rich.

Here are the results.. Any help is appreicated,as I dont really know how to read these things, or know what to look for. On a quick look over, i didnt notice any vacuum hose leaks, but it was a quick glance, and the engine was warm..
