Skippy the Megane - davemar
My Megane ('98 1.6 8v engine) has been very difficult to start recently. The starter turns, but the thing really struggles to fire up. It is much worse when the car has been left for a day or two. It has also been kangerooing while moving, particularly when cold.

The HT coils were replaced about a year ago, so I don't think they could have died by now. Would a fuel problem be possible?

Have a look for some recent posts on '98 Clio RXE 1.6's, same engine. A forum search should do it.

Could be the flywheel sensor.
