Having bought a Bravo 1.4 S with a siezed engine, i swapped it over with an engine out of a Brava 1.4 SX. Everything has been great apart from two problems. The fuel injector light on the dash board has been permantly on, and occasionally when the engine is idling, the engine will rev itself. I was wondering if it is a problem with the engine or is it the way i have connected something. Dont really want to have to pay a fiat garage to tell me it is a lose connection!!
(also been thinking of putting the ECU from the old car in, would this make a difference??)

Cheers for any input
