The Mégane II Owners' Club

well after one week of my car working well...(having had the throttle body cleaned) normal service has resumed. This means unresponsive engine, rough running, and poor throttle response. This has happened since i parked it this morning.

what could possibly cause the car to revert to poor running?..could it be the 'sensors' that adapt to the info on driving, fuel delivery etc?..i honestly thought id cracked then low and behold....any got any ideas on wether the electronics could have a part to play here? whole car feels very rough again and difficult to drive smoothly.

Its french - anything is possible ?!

Possible faulty throttle body?

hi iainMW

would this account for it running well when cleaned and then returning to poor running?....i hadnt thought of it.
