OK, could be my fault, but I doubt it.
Here's a chance for all the engine expects to give me a little advice.
Just changed the timing belts\tensioners\water pump\oil\antifreeze, on this
91 1.8L Laser.
After the change, the car started in one or two revs, on the first try, and
idled normally (although low, when warm).
Tried to adjust the idle RPM (was running about 680-690 RPM), by following
the SM. The idle position sensor is at exactly 0.508 volts, and is stable.
It increases as the throttle is opened. I also can't seem to increase the
idle RPM, the ECU still keeps it down a about 690
About a week later I went out to start the car (approx 4 degrees C) and it
stalled right after I released the key from the start position (back to the
run position). Tried again, same thing. Third time lucky the car continued
to run, but very roughly, then cleared up in about 5-10 seconds and ran
normally at slightly higher RPM (while cold, it dropped down when the engine
warmed up). After the engine was warm, the start issue wasn't and issue, it
didn't do it again.
Next day, cold engine, same thing, two no "runs", then it started. Once
warm all is OK.
Third day, same thing.
Perhaps another symptom. When I changed the oil it was black. The new oil
now, looks like light chocolate. Is there perhaps a cooling system leak
here. I've only driven the car around the block, to test it after the belt
change. I start it every few days just to keep the oil circulating.
So what has changed??
