In the last few weeks, on long (more than 30 minutes) trips at high speed, my V4 temporarily loses power and speed (i.e. seems to misfire), sometimes having to drop from 60 mph down to 40. What's more, it misbehaves for longer and longer periods. The carb is a Webber which I fitted in as-new condition a year ago. Any ideas? My thoughts are that it probably needs a new coil, but I can't really test it because it's an intermittent fault, so I thought I'd ask if others have had similar problems before I splash out...

Regards,

Alex

28/02/2006 17:43:30   Alex   Thanks all - I'd not thought of carb icing, but now it seems an obvious contender. Looking in the manual, the air filter has a 'winter' setting taking its air from above the exhaust - I've now changed this, and am hoping that that has cured the problem!

Otherwise, coil or condenser seems likely. It's too intermittent a fault to be the valves, and it stops when the car stops, which implies that it may be linked to hot electrics but not to hot engines. My Dad's theory is muck in the fuel filter, but then I'd not expect it to clear itself.
