Recently bought a Croma Turbo 2.0ie -89. It starts perfectly and runs smoothly on idle running. But when passing 2-3000 rpm, it starts to jump, caugh with uneven bumpy running. Anyonw have had similar problems? Can it be Fule pressure regulator or something else making it not get the amount of fuel correctly?? (Already changed fuel filter, spark plugs, oil, oil filter etc etc)

Check for water in the Full Power Enrichment Device connector, it's a small black box situated directly below the radiator expansion bottle.

It's dry clean.. Cant be that..

Hi,
I had a similar problem, solution was the short hose between fuel pump and cover part in the tank. So this little hose on the high pressure side of fuel could be damaged and fuel is liking, you can't notice that you are losing fuel, but actualy you do not have enough fuel. For me this was solution.
