Hey guys. I've posted once or twice on this forum before for my
fiancee's '95 Disco with the 3.9 V8. Responses seem helpful. I'm no
stranger to working on cars, but I am somewhat in the dark regarding
Land Rovers. I have a question for you guys:
Her check engine light decided to illuminate tonight. Background:
recently, the car has stalled out on me several times. Once right
after starting it, once while I was making a turn at a slow speed from
a light (so the engine was idling, essentially -- it's an auto tranny).
We decided to run some Techron fuel system cleaner through the tank
right before her last oil change. Not sure if it had much effect
besides a slight improvement in throttle response.
I have been very suspicious that the plug wires need to be changed. Is
there a possibility that bad plug wires would trigger a check engine
light? It's not flashing, just remaining illuminated. Correct me if
I'm wrong, but OBD II diagnostics came about for the '95 model and this
means we need a tech to turn off the light, pull the codes. Of course,
if he comes up with a P0300 (I think?) it's a misfire which would mean
bad plugs or possibly a screwed up crankshaft/camshaft (don't know
which these cars use) position sensor? Maybe the distributor?
What other things could cause the car to occasionally stall, idle a
little rough and turn on the check engine light?
We just replaced the air filter about two months ago, as well.
Thanks for any help. Oh, the car seems to running OK, minus the above
problems. Fuel mileage seems normal, so I'm not suspecting emissions
related problems (catylist, O2 sensors, etc)
