Question about 1999 Isuzu Rodeo
Little bit of grey smoke comes out on start up. only when cold in winter it starts up at accessories & not start position & the glow light stays on for 5 seconds longer. it doesn't idle well & have to warm up for 5 minutes. after its fine no issue at all
Sounds as though the cylinder,s etc are a bit clogged up, try some diesel fuel addative,as with all diesel engines if they do not get long and regular journeys the glow plugs,injectors etc get clogged ,as the engine does not get hot enough to burn these deposits off on short stop start types of journey's . you are possibly looking at replacing the glow plugs but give the addative a try and if possible take for a long drive 2-3 hours at steady highish speed , ok to repeat the addative and long drive once more ,if no improvement will need to go into the repair shop to have the glow plugs seen to at the very least , good luck

SOURCE: stalls and wont idle when cold
Re the trooper. You have a couple of possibles. The most likely is the glowplugs or glowplug relay. Don't be fooled into thinking glow plugs only heat to start - the also do whats called postheat. That is to raise the cylinder temp until the block is warm. IF they are not functioning (clip a light onto one whilst switching the glowplug on to test the relay) this is common.
Most likely is a stuck EGR valve - stuck open so running a very lean mix when cold. Its two bolts on the inlet manifold, pulls out and looks covered in soot - it should push in and spring out. Can be cleaned in petrol or alcohol or with compressed air.
More remote is possible you have a faulty injector...only really testable by an engine centre...

As your lights etc. are flickering too; check the engine; alternator; and, frame ground cables for a tight clean connection As your alternator charges your battery and, your starter just starts your car you can rule them out.

the flashing service light is cat protection mode. check cat convertor and exhaust for blockages.
check vacuum hose from fuel pressure regulator not leaking petrol into intake manifold by disconnecting while running.

Try changing the fuel filter and get the glow plugs checked or replaced .Diesel goes a little waxey in colder weather making it harder to go through the filter .
Hope this helps.
