Hello

I have 2001 Seicento Abarth with problem. Car is pulling okay to 3k rpm, al above is dead. In 5th gear i can bearly go 130km/h, most scenarios it get to 120 very slowly. Before this one i had 2004 SX and that car was going like rocket.

I dont know what problem could be, any help?

First maybe check the ignition, plugs, leads etc. If thats seems fine to a compression test sounds like a headgasket failure.

Management light on?

D

Does it have any fault code?

New spark plugs and new spark cabels

No menagments light

Sometimes i have problem with o2(lamda) sensor and i have some unknown code

I have car about 1 year and its always same power, also i was thinking about swaping engine

has the fuel filter ever been changed ? could also be fuel pump often easy to check the fuel pump in the fuel tank buy just taking it out its only a few bolts under the rear seat often the filter inside them gets clogged up causing fuel starvation

I went to the mechanic with my Sei. He couldnt find problem. Last thing he told me could be ECU or transmission. It is little harder to find parts for Sei in Croatia
