Could I get a pointer to a brief rundown on the symptom(s) of ailing CPS & MAF (Vanos too?)? I poked around using the search utility but coudln't find a a simple description. Reading up on the Bestian site re: Vanos sounds like what I'm experiencing - a slight "tugging", usually in 2nd gear, at low rpms. Get the occasional burp/lurch in 1st gear when leaving from a dead stop but nothing more. No real signs of power being down or rough idel etc. No CEL either. What's the likely culprit - MAF, CPS or Vanos (99 528IT 5spd 170k mi btw)? TIA
