:( Hi as a new member i wonder if anyone has experienced this one!I have a 99 2 litre 8v petrol and have owned for the last relatively trouble free 3 years until now my problem is after a faultless 50 mile trip the car was parked up and left overnight the next morning when started and gets worse when warm the car developes a serious flatspot making it virtually undriveable i have checked the usual plugs, leads even replaced the idle valve/stepper motor with a new one i removed the engine ecu and cleaned some corrosion off one terminal and when taken on roadtest it was fine until approx quarter mile from home it is now like it all the time there is no engine light on and a local garage has tested the coolant and map sensors and believes the ecu to be at fault has anyone had this happen before i go down the line of getting an ecu?Many thanks.
 
If it worked fine for a while after cleaning the ECU terminal I'd go back to that first.
