At low rpm, 1000-1500rpm, it seems to be loosing power. This is an intermittent fault and about 20% reproducible. under light acceleration there is a small surge of power which occasionally cuts out until the revs get back up to say 1700rpm. sometimes power comes back early but only returns for a second or two. During temprory power loss throttle position seems to have no affect at all. Remember lincomb farm? it kept stalling on that rather steep hill where i needed winching. Also recently during the cold weather it has stalled a couple times after the first 50 meters or so without letting it warm up beforehand.
the 24v is poor at low rpm and needs the fuel pump adjusted? well the reason i have not done this is that it is an intermittent fault, like if a ecu were restricting the engine temporarily as opposed to just low power at low rpm, and i would like to get this issue fixed before i start messing around with the fuel pump.
So far i have change the fuel filter, checked the air filter and run it without the fuel cap. all of this has had no effect. I have removed the back seats and checked the pick up pipe and it seems OK but there is dirt on the inside which cant be cleaned easily so have ordered a new one. If this will not work then i will assume the fuel delivery system is not at fault and its either the EGR, fuel pump or injectors.
I have blocked of the EGR
there is also this:
Seeing as the EGR is blocked off then this should not no effect, am i right?
I could also try to run it with a gallon tank piped directly into the fuel pump just to be sure that the fuel delivery to the pump is not at fault. Do you think i should do this next?
Have i missed anything? What do you guys think?
