c200k fault code p0172 (brain in meltdown)

[matt123]

Hi being trying to sort my c200k with fault code P0172 rich running.. has anyone got a possible answer to this? so far its had new wiring loom and cam sensor with blockers.. lambda sensor (both), Maf sensor and the whole system smoke pro'd to detect any intake leaks.. so far no joy.. Any pointers will be much appreciated..

get it on a star machine mate. No point of throwing parts at it. Where are you located someone on here may be able to recommend a good indie mechanic.

Cleaned the throttle body?

Was the wiring loom contaminated with oil?

I have had it before on a few m111 evo engines, unless yours has the 271 engine? But I doubt it as you had oil ingests in the harness, if its a 271 then it will be the breather hose under the airbox.

HI im going to double check the pipe today, i had the whole intake system filled with smoke to detect any leaks, but will double check today..
