My car keep judering

[_drew]

My car keeps juddering when i acelarate, its not the coil pack as i only changed it two months ago. Sometimes i can drive as fast as i want and it will drive smooth as but then sometimes it will just keep juddering on low accelaration.

Any ideas what this might be?

Sounds like a misfire?

Plugs, leads?

Dodgy fuel?

No i changed the plugs when i changed the coil pack, and the pack came with new leads. I thought i could ofg been dodgy fuel but i brimmed it with superunleaded and redex system cleaner and no difference:/

Bad earth when fitting coil pack?

Dodgy connection on plug to coil?

Is it single coils or one coil?

Coil pack is fitted fine and only 1 coil

could be many things fuelling or ignition related; injector, plug(s), coil pack (just because its had a new cheap unit doesn't rule it out i'm afraid), throttle body or potentiometer.

Micks standard reply: Diagnostics
