03 Megane Misfire with no Engine Light

    I recently got a new car, well "newer" than my old one anyway, its an 03 Renault Megane with the 1.4 16v 98bhp engine. Ive been noticing that between roughly 1700 to 2100 rpm that the car misfires. It idles normally.

    I swapped the ignition coils one by one and upon replacing the 4th coil, the car wasn't as sluggish in 1st gear and the car was misfiring less frequently, but there was no engine light showing up on the dash at all and I even checked it out with my OBD2 diagnostic computer and there was no fault codes at all.

    The car itself was lying up for a few months before I got it, so I was thinking that maybe it could be dirt in one of the filters or a problem with one of the spark plugs

    Any ideas to why this misfire would be happening would be great, thanks :D
