Hi, any panda owners have a similar problem to this 1992 Uno (Same engine as the Panda)?

Traveling on motorway up an incline about 70 mph and pulling relatively hard, (only uphill!)the uno will start to loose power in pulses, causing the car to surge. Finally it will cause a cut out altogether. The car runs fine must of the time, can be a little rough in the morning, not starting as good as it used to. Temperature running at 2 ticks above normal, fan runs fine. Loosing a bit of fluid in the radiator (down to min)

I have replaced the thermostat, fuel pump, fuel filter, fitted a replacement ECU, distributor and coil!, new HT leads, cleaned the plugs etc... Luckily most of this is from the scrapyard but my patience is wearing thin!!! All ideas appreciated.

My last option is the cylinder head gasket or a replacement carbie?

Cheers, Dave

Some of the symptoms you describe match

Do the clean-up described by Morten first though..

Thanks for the link,

I could hear boiling(?) in the heater pipes last night, so plan is to go for a new cylinder head gasket.
