there's a flat spot around 3k revs but the k&n should iron that problem out. First things first, Replace the spark plugs with Bosch Super4's and replace the ignition leads. see how that goes, if money isn't a problem, go for Magnecor Leads.

If that don't fix it, could be the Lambda sensor which are about 60 to replace. It's a much needed item and VERY delicate so if you remove it, DON'T drop it, or it's a trip to fiat for a replacement.

Other symptoms may include, blocked fuel filter, blocked injector and incorrect fuel pressure.

Hope that helps

Sorry, hate to be a to$$er, but bosch plugs dont really agree with fiat engines. We fitted loads on services and most came back within 3 or 4 weeks with missing and backfiring problems. Replaced the plugs with NGK's and they run fine after that. [8)]

I have Champion EON and have noticed no difference between them and my Fiat 1's except price and the life span 36,000 or 3 years on the Champions :)

When mine is cold there is a bit of a flat spot around 2.5k, only for a few minutes when first started though. Dont notice it anymore though, I start the engine in a morning and then have a fag. By the time I've finished the fag the engine and car is warm and mist free inside:D!

Very technical instructions on removing cold flat spot (only for advanced mechanics):

1, start engine

2, have fag

3, when fag is finished, get in car and drive off

My car could rattle itself to bits on the way home and my head could be pierced by a stray part of bonnet.

Have to say I think Super 4's work well on cinq/sei engines.
