the last time i had this happen to me i had a burnt valve. if it hasnt had a valve job in a while you may need one. also ive had the same problem when the vics, egr, and idle air bypass were all disconnected (they must be crazy asking for $600 ea). check linkages, hoses to each and do a compression test.

These pictures were taken when I did the headgasket a few months ago. The valves looked fine then, and I've done my best to keep the engine in good shape.
MAF/VAF These do the same job, but different ways on different years right? I thought there was a wiring issue with swapping these? I do have 2 airflow sensors. I've tried swapping them without any difference.

I see maybe 5 burnt valves...
See where they're only black on one little portion? Thats a bad sign.
S code is for the 1.6L's and the B8.
U code is for the BP.
I no longer have the speedo cable... I think. I can check for you, but it made noise in cold cold weather (-20C or more)
What are your compression numbers?

It would be cheaper to buy a new B6 with good compression than to get those valves repaired.

?Why would I buy a B6? I like my powerless BP...
I found a BP05 head for $225 after shipping. It's in Spokane, so it'd ship here quick.
BUT am I asking for problems if I hold off on rebuilding the bottom end until I have enough cash to do so?
I figure since I don't have a core on the head I can rebuild it while the old one is going out; and then buy a block and rebuild it... (but that might be months out)
And I still haven't done a compression test. Harbor freight has cheap testers right?

I figure I could get a gasket set, rebuild the head, port and polish and then put it all back together. Maybe some performance stuff too.
