What spec/ model brava have you got?
Charlie . marea jtd
1.6 16 valve sx - 5 door fiat brava. registered in 1998 - has been with same family since registration and only done 104k - low miles for 19 year old car.
i am having a lot of trouble with it at the Moment. ECU messed up , Cambelt slipped and emissions went through roof!! Bought new timing belt (£90 if you don't mind!!) got it all changed and timed etc - still ran like pig so bought new exhaust sensor - still runs erratic - so, bought another ECU - runs ok when first start up but when auto choke goes off it starts to run erratic again and sometimes backfires slightly. Have tried to read both the ecu's but cannot get any reading. the diagnostic says 'ERROR'. Tried getting it read professionally but to no avail - they say as it is not a Bosch ECU their equipment cant read it!!!
Any ideas on how i can fix my car and especially HOW I CAN READ MY ECU - its a Magneti Marelli.
Appreciate any help from anyone as really cheesed off :bang: Thanks

these are all 3-pin ..as your brava is only obd generation1
where is the car based..?
it's based in LINCOLN LN6. Thanks for info, much appreciated. I am going to check this out with my diagnostic equipment disc as there is a free update service that i am hoping might give me obd1 . Cheers
OBD1 was the BASIC original On Board Diagnostic standard
later replaced by OBD 2 - with a multipin socket
engine-wise the FREE version of multiECUscan should be fine..
you just need the cable to connect to the 3-pin socket

Hi there,
Since yours is an early car the engine systems should be fairly simple, so you should probably go back to basics.
If you've had it for a long time then any faults will have developed recently, it's not like you bought the car with an unknown history and are now trying to debug it.
If the cambelt slipped then it's possible you may have bent a valve, you should do an old-fashioned compression check and hope to get around 180 PSI on all cylinders with the throttle wide open.
The diagnostics should give basic information if anything is wrong, you have changed the single lambda sensor so apart from the water temp sensor there should not be too many inputs to the ECU apart from throttle position and airflow etc. Sometimes throttle bodies need a clean but that is progressive deterioration.
Otherwise I guess you have individual injectors and maybe coils for each cylinder, check these and of course the usual stuff like plugs and leads. Sometimes if you do repairs or maintenance you can disturb an old, failing component and introduce a problem where everything seemed to be fine beforehand.
You don't suggest it is misfiring, so maybe all cyclinders are the same and it's something higher up in the system common to all 4.
Hope it gets sorted soon.
Cheers
John
