[brends]

Lovely vehicle hopefully i can sort the few problems out

Hi lots of help on here

[brends]

New turbo and everything sorted except 3 problems. It cuts out when changing between park and reverse and neutral and drive. Struggles to start cold but then no problem starting till next morning. And very low power. Any suggestions

Welcome along. Sounds like cold start is your plugs. Have your air separator/ splitter it may need cleaning as it clogs with carbon, and have you checked your air filter aswell

[jimmyrev3]

do a code read then disconnect battery for few hours then reconnect this may reset ecu

[brends]

Thanks guys new glow plugs going in tomorrow. New air filter and air seperator done last night. Code reader on its way.

Was the air separator clogged

Just a little bit of muck

Installed a boost regulator and gauge upped the boost a bit. It does go better but still only 30 up hills on the highway with the motor at 3500rpm

Injection quantity depends on mass air flow, could be your turbo isn't blowing much or the MAF sensor isn't registering all the air going through?
