how u all doin i have a problem with my 2005 mg zr 105
The thing is i had a bad misfire so decided to change the coil packs and plugs which sorted it, but the other day while driving along the car started to what i think was misfire then the engine management light flashed on and when i slowed down it went off, i have found also that when quickly accelerating away and hitting the 4000rpm it starts to misfire again but no management light. can anyone help pinpoint the problem as it is really doing my head in
many thanks!!!!!!

fuel filter is mounted right next to the coolant bottle on the bulk head it i silver cylinder with solid pipe comin out of top and bottom it in a black bracket you will have to remove coolant bottle to get filter off but the coolant bottle just lifts out mate.

cheers mate checked all the connectors on the coil packs gave them a wee spray with wd40 and put some injector cleaner in seems to be going good fingers crossed think it may have been dirty fuel
