Tickover intermittent
« on: 06 December 2014, 14:44:01 »
My 1999 MV6 manual has recently taken to losing its tickover intermittently. It's usually ok  from cold and will drive happily for a while (length of time/distance varies), but then will not tickover, and loses some power and drives lumpy (but still on 6 cylinders). Sometimes it recovers and drives fine again. If I park it till cold, its ok again. Any ideas?   :'(

Your description covers a few common causes.

1 tickover or stalling alone symptom is usually down to the idle control valve on the side of the plenum sticking. A good flush out with crab cleaner and some light lube usually fixes that.

2 loss of power on all 6 cylinders could be anything from a maf fault to crank sensor which can also cause a stall.

3 engine temp related issues also points to crank sensor, as the cable is clipped to hot oil pipes at the back of the engine. Quite common.

4 don't count out a faulty coil pac, but probably least likely given your description.

I guess clean icv and check for engine fault codes here

Code 19 is crank sensor

Then see how you go.

Hey, thanks guys! I 'll start with the Crab Cleaner (still have some from when I was single), and if that fails, I'll check out the crank sensor. The way it comes and goes, I suspect it'll be that.  :y Cheers.
