Model Boat Mayhem

This has nothing to do with model boats, although I am a model boater. I know that we have some forum members who are very knowledgable about cars. My problem, I drive a 1994 Rover Metro 1100 S, and up until 2 months ago it went with no problems whatsoever. When ticking over correctly, it ran at about 1000 rpm. When the problems started, the ticking over revs dropped to about 100 or 200, and sometimes the engine stalled. The next symptom to appear was when cruising at 40 to 50 mph, the whole car started juddering and vibrating. The only way I can clear it is to change down into third, give it some wellie, then change up.
I have put it into two garages for attention, just had a 12000 mile full servicing done, but the problem is still there. This is driving me nuts, so apart from putting it in the scrapyard, has anyone any ideas, please? Many thanks, Pete M

i had the same problem years ago something to do with the filler cap breather hole ? got blocked up
-
try driving around a short circuit WITHOUT the petrol cap in, but low enough fuel as to not slosh around your tank and spill out. if it STILL does it, then its NOT your tank breather.
check your fuel filter as well, have you let your tank run low at all, (like in the red) or have you at any point ran out of fuel?

more than likely to to be a water leak into a cylinder, this will not cause misfiring but a loss in power, or the distributer cap might be dirty or old plugs and leads. The list could be endless!!

Dear Pete,
Sounds like a carburetor tuning problem. One solution is to get the vehicle tuned on a rolling road, the people who run such will I am sure sort this out for you. If you have a prob. getting hold of of such a facility (after looking at the Yellow Pages), find the nearest rally club and they will tell you straight away.
An idling speed of 1000rpm sounds a touch high? 5-600 would be nearer the mark I would have thought.
Regards, Bernard

It's probably fuel injected given the cars vintage. As someone pointed out, the fault could be linked to fueling or ignition,could be an engine sensor playing up, or a coil pack going west, dodgy fuel pump, blocked injectors, blocked fuel filter. On and on, impossible to diagnose on a forum like this.
At the very least a competent mechanic should be able to plug it into a diagnostic computer and see if all the sensors are doing what they should.

Join the RAC. A?.. A?

Start simple...
Replace the air filter... What's the fuel consumption like?
If its a Fuel injection rather than a Carb, start thinking a sensor somewhere..

Thanks to everyone for all the suggestions. I have made a note of every one of them, but first of all I will call on the AA, then if they cant sort it out, I will work my way through the list. As usual, forum members have come up trumps. Many thanks, Pete M

Peterm,
Can you confirm it is a "K" series Carburettor Engine?

Check the exhaust and catalytic converter is not blocked, the baffles collapse and partially block the exhaust this will give you the symptom's you described.
-
The idling problem sounds like too much air so mixture wrong. If carburettor check crankcase breather tube is not perished.
-
It does sound like too much air getting in at idle. My '70s Cortina did exactly that when the carb (which was apparently cast by the same people who make aero bars) "went porous". If it happened very shortly after a service, have a close look at all the odd bits of hose in the area of the inlet manifold. You never know what was nudged while the mechanic had his hands in there.

It is peculiar that this engine problem clears after a thrash, one area to check could be water in the fuel tank. I don't know about Metro's but some vehicles have a steel petrol fiiler pipe which runs through the rear wheel arch. Given the lousy quality of the steel used on a lot of Rover cars, this can go rusty and perforate. Water spray from the rear wheel enters the fuel tank via the perforated steel filler pipe.
It's something worth checking as I have owned one or two vehicles with this type of problem and they both displayed similar symptons to your Metro.

Once again, thanks to all. I am checking evertthing that has been mentioned. When (if) the problem is sorted I will let you know the answer. Pete M
