slight miss fire

my 1.8 16v has developed a slight missfire at around 2250 rpm, and feels a bit flat under load in top. Any ideas, and how to check your suggestions out?

Jack the easiest way to check the leads is to pull one off at a time wnile it`s running and see if the engine drops in revs wink

if it does`nt chances are that lead is duff
eek! eek! bugger might not work on a twinspark but does on convential motor anyway give it a go

Btw dont touch any part of the car with the rest of your body or you will earth yourself out and get a nasty shock eek! eek!

thanks speedy but i think it is morelikely to be a dodgy sensor, possibly the lambda probe. It has been on for 60K miles now so prob due for a new one. Incidentally there is a guy on ebay selling lambdas for 18 NEW

I have recently changed the thermostat cos it was stuck open and the car was not getting any way near warm. I also changed the temp sensor. Got one for 7:50 from local motor factors they even had one on the shelf. Now runs a treat, touch wood. It seems the tempsensor is shared with most fiats and alfas. It is not a genuine bosch part but seems to work fine.
