Back again guys - Hurray!! After three years away from Landie forums.
I have a quezzo from my Dad, he is pulling his hair out ATM over the engine peoblems he is having with his 99MY 4.0 Litre Bosch Motronic V8.
When the engine runs from cold there is no power and the unit will back fire, die, rev limit to 3,000rpm etc.... Once up to temperature it is spot on as normal.
He has changed the coolant temp sensor, the throttle pot, disconected the battery to hopefully reset the ECU. All with no result :-(
Fuel pressure is fine.
Diag tool on OBD2 annunciates the fault code for left and right bank lean mixture - no sh*t
Any ideas?
