Evening all,
I've noticed that my '97 Mondeo seems to come close to stalling sometimes, when cold and under load (i.e. with headlights and heated windows on).
It doesn't happen when standing still. When I'm driving and approaching a junction or coming to a halt and I disengage the clutch and knock it into neutral, the revs drop to the point where you can hear the engine struggling and the lights start to dim. This only happens for a fraction of a second and then the revs rise back to normal.
It's fine when warmed up. I'm no mechanic by any stretch of the imagination, but my best guess is that the ISCV is gunked up which is why it takes longer to react when cold.
Is that anywhere near an accurate diagnosis? If so, could this be a DIY job with some carb cleaner?
If not, any suggestions?
Ta,
Chris.
