TD5 runs bad help please

hi i got shot of my old landy which i regret and brought a Td5 at the auction 2004 90 for 6k which i thought was good,but it runs crap very bad on low power ,checked loom fine ,changed mass air flow meter and turbo actuvator any other surgestions

have you checked loom at both injector and ecu ends?
fault code reader been plugged in yet?

hi i have checked it at ecu end red plug but not any where else where else should i check

Check fuel filter and air filter.
Make sure intercooler hoses are sound.
EGR valve may be stuck open.
Maybe running in limp mode if one of the engine sensors is kaput.
You need to get a diagnostics read out to give you a clue.

thanks for that i done 3 things tonight checked the loom by the head for oil there is a trace in the plug bit,on the air box there is a sensor that plug looked dry like the air flow one aswell so i gave them a sqirt with some silocone spray now it runs a treat but what one was it loom or conections also will it still smoke like a pig for the first 30 seconds in the morning,want to by a nanocom is it worth it?
Thanks again
i will post the cold start isuee tomorrow night when i try her to see if it smokes like a pig
