jtd m-jet bit sluggish under 2k
Hi everyone, I have a strange issue with my 2003 jtd m-jet 140ps.
The engine has been completely rebuilt, new turbo,decat and modified head.
EGR blanked off (This problem is not a stuck EGR..!")
Oil recirc blanked (now goes to catch tank)
The engine most of the time feels very sluggish under 2krpm, and the turbo seems to take ages to spool up, occassionally it seems a bit smokey under 2krpm as well.
I'm wondering if the MAF is a bit dodgy, maybe the connector pins need a clean (the sensor unit had been alcohol cleaned and looks very good)
Any ideas ? ~ I just dont see that it is a mechanical problem, more of a sensor issue i rekon.
