I have an alpha romeo 159 tbi 1750
Yesterday i faced a problem, engine light come o the dash bord I have 2 fault code one is p 240 overboost pressure and the other one is heat of lambda sensor.
When i open to check the engine i sow the exhaust too hot at the point that is too red.
Can some body guide me what should i do and what to check, the acceleration actually is not as before.
Thanks and regards
Walid
