Mis Fire At 2000 Revs

[eddy1]

hi, I have a deisiel 1.9 2001, the engine mis fires at 2000 rev in all gears, then accel ok.

 

Then every now and again total lose of engine power on steep hills, It happens at all speeds , and reduces the speed from 80 to 10 miles per hour, hazard lights are getting a lot of use at the moment!! inbetween the car flies along?

 

Any suggestions would be welcolmed

gutless on hills = good chance that the MAF needs replacing

[Neils TDi again]

Yep

 

Defo the MAF, unplug it and try without, if its got "go" again, get new one

Check the wiring loom to the injectors - known problem for bad connection at injector to cause rough running.

 

Check vacuum pipes and connections - there are quite a few - there is a small vacuum reservoir the size of a tennis ball at the front of the engine - check the pipe going into this. Loss of vacuum causes the ECU to trip into limp home mode.
