[s-cars] Bucking s4?

[Cody Payne]

Chris,
	If it was your moisture trap...i.e- hose fell off or cracked you would have only 5 PSI or so of boost...at least that is what I experienced.

If the car is bucking under load...I would look towards:
-1) Faulty Knock Sensor (check your DTC's w/ someone w/ VAG tool or a paperclip and code xlation sheet from SJM Auto website)
-2) Wastegate flap or BPV flap under load...check BPV 1st...do wastegate mod 2nd.
-3) Ignition problem..perhaps POS (never had any experience here)
-4) Hot temps causing retardation of boost and timing see #1 above
-5) Fuel Filter clogged or Fuel pump going out.
-6) Crappy fuel

Scott,

I'll look at it, but what am I looking for when I loook at it?
Will this casue it to always buck, or just when it's hot out. It bucked
last night immediately after starting it (97 degrees outside), but not
at all this morning (65 degrees?).

Thanks for the information
Chris
