Please can anyone offer some assistance on this one?
I have the above fault code & was experiencing a lot of power loss under 2,000 rpm. I replaced the egr valve but the emissions light is still on. A mate then cleaned the vacuum / boost sensor & cleared the fault. After a test run the car was running great but the following day the car stammered once or twice at low revs & brought the same fault up.
Would you recommend replacing the vacuum / boost sensor or is there something else causing this?
