1.6TD cold start stutter
« on: Mar 30, 17, 04:34 »
My 1990 1.6TD has always performed cold starts flawlessly, but this week it started to stutter (felt like it was running on 2-3 cylinders), despite having the cold start lever pulled.  I think 1 or 2 cylinders aren't igniting, it certainly feels that way.  The issue goes away as soon as I rev it up to around 1,500~2,000 rpm.

* after I take the revs up to 1,500~2,000, I can release the throttle and it will idle perfectly (but it won't do so until I rev it). 
* the stutter only happens on cold starts

you probably have 1 dead glow plug.  If you had 2 dead it probably would not start at all

pull them out one by one and see if they all glow red when you put 12V to them.

You can fire a diesel without any glow plugs, and you could just test the resistance of the glow plugs with a multi meter then replace the one that's out of spec.

Considering they're under 20 bucks a pop, I'd just do the lot after going over the wiring if you don't think they've been done in a long time. Fresh plugs and good compression these motors will fire up no problem in -15 with a few runs of the plugs.

Thanks, I'll test with multimeter.

It started everytime within a few cranks this winter on the coldest mornings. These engines are godlike.
