Right, had a spot of bother with my car this morning - it's a 156 1.8l T Spark. No, that's not the problem, before I get the smartarse
When I turned the engine over this morning, it caught immediately (as
usual), the revs went up, and then down (as usual), down past 1000rpm (not
usual) and the engine simply cut out.
Strange, I thought, and did it again. The same - the engine caught
immediately, but as the revs came down, instead of settling at 1000-1100 rpm
as it usually does, the revs kept dropping and the engine cut out.
I got out, popped the bonnet and had a quick look, there was nothin
obviously wrong. Back to the cabin, turned the engine over - this time it
started as before, but settled at about 1000rpm as usual.
I drove into work, watching my idle speed carefully where necessary - the
rev counter shows that the engine is varying more violently around the idle
mark than usual - normally it's about 1000 +/- 100rpm - now it's about 1000
+/- 250rpm - the red zone on the engine is about 750rpm so it does get close
to cutting out.
Any ideas where to start looking for the problem? The car was serviced
about a month ago, and got new belts (timing & auxiliary drive), new plugs,
and a new variator.
