hi guys im new here. I have a bmw 316ise 2001 with the engine management light and the revs go up and down occasionary. on two occasions in 2 months it could not start. After I pressed the clutch a few times it started. I had a diagnosis at the mechanics at the EOBD code reading was PO170 which could be either intake leak,Air system,fuel pressure/pump, injectors, EVAP canister purge valve or HO2s. Does anybody know what the problem specifically is? The mechanic dont seem to know. Thank you in advance.
