My mother in law has a sick car. Apart from the unbelievable quantities of oil its consuming (seems to be crankshaft oilseal), it runs terribly. Its a 4 year old Renault 4 - so there's definitely nothing flash about its specification! Symptoms: Takes 5-6 miles to warm up, until then, have to have plenty of choke (so plugs are always nice and black). Without choke the engine just about dies; however if you can get it to struggle through for 10 seconds, the motor suddenly picks up properly. Dwell angle is fine - just under 60�. The reading is rock steady (so I don't suspect a worn shaft), and the points are in good condition. However, when you accelerate, it drops back to 50�, as the engine dies. This I know shouldn't happen - fluctuation should be a couple of degrees at most. I can't see the timing mark with a strobe (so it is way out); however there doesn't seem to much point in looking at this until the dwell angle problem is sorted out. Anyone got any ideas what I should try first? Cheers Steve

This seems as good a place as any to get some advice on a problem I
have just now.
I drive a Nova 1200 Merit and recently it's running like there was
treacle in the tank!
It usually starts OK but driving around town or motorways I can have
my foot to the floor and be getting almost nowhere then it seems to
surge and then fall back again.
Consulting my trusty "AA book of the car" I found that the fuel supply
is fine,the filter is clean as a whistle,but as far as I can make out,
the advance/retard vacuum unit is a goner.
What are the symptoms if this is the case?
There appears to be a fluttering noise from the engine and I don't
think the fuel consumption is very efficient.
The way I see it is that the a/r unit may have been out for a while
and the timing has got steadily worse.
Also ,will the carburettor be sucking in air when it should be creating
a vacuum?
Keeping the choke out helps slightly but can result in flooding.
Any of this sound remotely sensible?
Opinions please.

I used to have a VW Polo which after a service decided that after about
50mph it would start to decelerate. The problem was that to points were
to wide.
I very really take a car into a garage but when I do the result is
always amusing :-(

My old Mini used to do that, for some reason the alternator had burnt
out and this made the car decelerate above 60mph down to 20mph for
about 2-3 mins then it would clear and off we would go again.
Most distressing at the time.
Matt.
