CEL has gone on and off repeatedly for a year: alternates between "Misfire on Cyl 1" code and Emission codes (several). What has been replaced: DPF (above the EGR), the EGR, the ignition coil, all the plugs and plug wires; the head gasket/coolant (supposedly coolant was leaking thru gasket). After this latest, thought engine really would work well. HAH! CEL on and off twice in week since
What should be checked/fixed? (Had compression checked, supposedly ok one mechanic said, another
said no, low compression intermittently on cyl 1)
have the same problem?
