97 D1, 285,000 km. plugs, wires, battery, cats, air and fuel filters all changed within last 3000 km.
The truck stalled on me (in the middle of an intersection while turning through oncoming traffic no less) last night on my way home from work. It did it again on the way to work this morning, and no less than 7 or 8 times while I had it idling in the parking lot during my 1 hour lunch break.
It will do it both while idling and under load driving down the road...it will suddenly sputter and quickly die with no warning. Truck runs fine otherwise. Sometimes it starts nicely, other times it takes several tries and much mashing of the skinny peddle to get it to fire...with mixed results. It also seems to start fine after it has been sitting for a while, only has a hard time starting after it has stalled.
I had it idling for a good 15 minutes at one point until it died. Once I got it restarted it then died 3 times in under 5 minutes only to run fine again for 10 minutes after that.
I understand a bad/dirty stepper motor can cause it to die at idle, but would this also happen while driving down the road with my foot on the gas? I've done some searching and there seem to be several other culprits, CkPS, fuel pump, TPS to name a few, but I'm not sure which one could cause it to die both at idle and under load...unless more than one thing has gone wrong at the same time. Is there anything I'm missing or should be looking to check first?
A few possibly related symptoms I have had include...
Last winter in the -40 cold it would occasionally not hold idle once the choke was off (had to put in neutral and hold my foot on the gas to keep it running at intersections etc...). It always started no matter how cold it was, just keeping it going with the choke off was the issue.
Also the last few months I have noticed that when I start the truck first thing in the morning (or when it has been sitting for quite a while) the engine surges to around 1500 RPM and holds itself there for 10 seconds or so until it creeps back down to a normal idle (or at the very least where the choke wants to keep it at 1K).
I do have an alternator going bad...sounds like the rear bearing has been chewing itself up for quite a while but I haven't seemed to get any charging issues because of it, money has been too tight to swap it with all the other stuff going wrong.
