Stock fuel pump, no measurements. Should I first try the regulator, who knows how old it is. This is AndrewWK's old S6 Avant

I changed the spark plugs, crossing my fingers hope that should be it. I could source a coilpack if need be from my friend. Next is the fuel filter, engine flush, valve cover gasket, oil change. After that is timing belt and high presure steering hose.

Are you running the MTM chips? I believe it had MRC chips in it, when you picked it up.

Not shuttering or misfire. Did the timing belt, fan clutch, and bearing for the fan clutch, alternator pulley, and high presure steering hose done.

Will do engine flush and oil change within week

My bad, I meant MRC1. Yes, MRC is still in it, was thinking of changing it out to the MTM to see if anything changes..I also think the cats are clogged, would this be part of the issue? Terrible eggy smell after smashing the gas for a bit.

I am assuming the 1.9bar wastegate spring is still in, as well? If the cats are clogged that could definitely be a problem. Do they tailpipe sniff where you are? I don't think it would be too hard gut them, as they are located under the car, so you wouldn't have to mess with the downpipe, but the fittings aren't in the best of shape. If you want a quicker reply, try my email, I have a horrible time trying to track my posts on this vbulletin crap.
