I just installed a rebuilt 20v head, water pump, all tension rollers along with the usual gaskets and so on. On my `03 VW NB 1.8 Turbo. Now it has a misfire at low r's idles rough and reads a p0171 and a p0016 that's the only codes I get. I've checked the usual vacuum leaks any suggestions? I bought this car with the top end torn down so I don't know if it's an ongoing problem.

Worried about P0016 since you had to redo the cylinder head. Check to make sure your cam is not off by 1 tooth.

Then for the vacuum leak, check Long Term Fuel Trim and Short Term Fuel Trim and report back.

Many places for vacuum leaks, but cam timing could be a source of your problem as well?

When in doubt you can always try to smoke test as well.
