Hi all, new on here so be gentle with me :grin:

I have a 52 plate (2002) L200 4Life and to day experienced a rather large power loss whilst towing.

I had a trailer of hay on the back, about 100 bales for the farm types amongst us :grin: , and to start with could not get above approx 40 mph, after a while the engine check lamp came on (bottom left of instrument panel, engine shaped symbol?), and power dropped enough to slow me to 20 mph. I stopped and checked the simple things like air filter and the fuel filter drain, as well as a visual inspection of the boost hoses and vacuum lines - nothing instantly recognisable as a fault.

After switching off the engine and restarting, the inspection lamp went off. The engine revs freely to the red line - no problem - so swapped loads for an empty trailer and progressed back to base. On the way back, it cruised happily at 60 mph with no problems.

Does anyone have any pointers as to where to start looking as the truck will be needed quite a lot over the next few weeks

:00000732: to the forums

lack of power under load problem check

spark plugs/ the leads / dissy cap

if a diesel

engine timing

May be it´s a problem of the sensor which checks the airtemperature for the turbo which is called air-mass flow sensor.

The best will be you contact the Mitsubishi garage, they connect the diagnosis system with your car and read the error memory.

I recently had my engine light come on, Mitsu dealer changed the fuel filter but light came back on. Then Mitsu dealer ran a diagnostics and found no error code stored on ECU (or so they say). Mitsu dealer test drove vehile until light came on again. Diagnostics showed a lack of vacuum. I specifically asked if the EGR valve was getting carbon build-up. The mechanic said something like that, they removed a part and sprayed it... I strongly suspect the EGR valve. I am only doing 25000 kms and got this problem.

When engine light is on the A/C does not kool and the van does not want to go faster than 90km/hr. If i turn the ignition key on and off a few times and the engine light does eventually go off then the van has all the power again.
