Hey guys,
I have been around german cars a bit now, couple of stage III s4's and a handful of other vdubs(gti's, jetta's). Currently we are trying to sell our Beetle but it is having some issues.
so far I have replaced all the plugs, replaced coils packs 2 and 3, cleaned the throttle body (then adapted it) and replaced all of the vacuum lines.
what it is doing
with a cold start in the morning it runs really rough, almost to the point that the gas pedal has no power, then when you start to drive the car it jerks. when that stops after warming up at idle it sounds like it knocking.
the boost gauge reads 10(Should be around 20) for vacuum at idle and when it gets into boost makes a detonation noise. It use to stall, hasn't for a little bit, but would do it on hills coming to a stop.
I have been digging around under the hood trying to figure out what the deal is, today I pulled out the evp purge valve and just stuck the to hoses together and it runs better but still not great.
The one thing that is weird is all the problems got worse after I put in the new plugs and cleaned up. The mpg is terrible something like 15mpg. Anything you all can do to help would be great,
