Diesel cold start idle problem

[tdipajero]

i own a 1998 turbo diesel pajero. on a cold morning the engine runs very rough at 200-400rpm. i replaced the glow pluga and injectors and adjusted the timming. this did not help? does anyone have any ideas?

you sure you glow plugs are working?? I would check them again if the priblom only happens on a cold start. how long does it take to get to a normal idle??

[Vineboy]

Are you REALLY sure you have put in the right plugs? My non-turbo 2.8 had turbo plugs in it and it ran like a dog. Once I put in the right plugs cold starts are no problemo.

it takes about i min to get to the correct idle speed

G-day Tdi,

I had similar problems a number of years ago with my 95 Tdi Paj and new glowies did nothing, it was found to be the connections to the bus bar from the wiring loom and the wire itself. It couldn't deliver the juice for startup and hence poor starting, oh and a sh*t load of heat in the wiring. It can really only be power or plug mate as it is a pretty simple system. Obviously if you stuff around with other things you introduce more problems.

If you've changed the glowies, get a sparky to do a resistance check across your glow plug assembly when the juice should be flowing (first 2 min of startup) and see if this is causing your trouble mate :thumb:


Cheers..........

This may be way off base but I have a 2.8 diesel lux that wouldn't idle when cold. I changed plugs, relays etc, no change...
