Yep, bought a 2004 DiD manual GLX on tuesday. 94,000kms on the clock, very neat and tidy. Had it's log book services every 15,000 (would have liked to see 7500 intervals, but nevermind). Drove like a dream on the test drive.
The same afternoon as I picked it up (only 2 days ago), the trouble began. It started surging and felt like it was misfiring at light throttle opening below about 2000rpm. Once over 2000rpm and the boost started to build, it cleared up and went like a rocket. Even when playing up, there is absolutely no smoke coming out the exhaust.
Yesterday it started playing up big time. It was a constant struggle for me to get the car home from work as it was constantly surging and jerking around. I would literally have to get to the speed limit as fast as I could and then push the clutch in and coast. At idle it is fine and even when I don't use the accelerator and slow down using engine braking it is smooth as silk.
This morning i took the car to my local Mitsubishi dealer to have the codes checked in the ECU. Surprise, surprise, there were no codes logged. They checked out a 'Map sensor filter', the EGR valve and the throttle butterfly, all appear to be fine.
This afternoon, I opened up the fuel tank and checked the in tank strainer / filter. It was as clean as a whistle. Then I drained the diesel filter (which was changed at the 90,000 service on 1st june this year) in the engine bay and hooked it up to a fresh, clean jerry of diesel and ran the car from that. No difference, if you hold the revs up around 2000, it surges, misfires and carries on. Still no smoke out the exhaust though.
I then removed the battery and disconnected all of the plugs around the injector pump and proceeded to try and remove the primary and backup speed sensors. I managed to get the backup sensor out, but couldn't get the primary one out with the tools that I have here at home. I did manage to get the connector on and off of the primary sensor a few times, just to make sure the electrical connection was good. So i put it all back together again hoping that the disturbance of all the electrical connections might have helped. No such luck.....
So it is going to have to sit in the garage for a few weeks until I have the money and can afford to take it to a diesel specialist for diagnosis.
I am really hoping that it just turns out to only be a knackered injector and not an injector pump or something else expensive.
Does anyone have any suggestions for me of what to check next, or of any components that may be causing this problem?
It seems weird to me that it is still starting and idling beautifully. Would it possibly still do this with a crook injector?
Thanks in advance, Dan.
