lumpy

[cerbieboy]

hello all.
just been out for a spin to blow the cobwebs away. and the cerb is running a little lumpy at low revs and under acceleration. not terribly but enough to be noticed. it almost like a flat spot. any ideas?
cheers

Could be a plug / lead / coil pack breaking down. Start with these as this is an easy change to make and go from there.

i just changed all mine and although straight forward looks like i have been trying to cut my wrists. my car used to miss around the 3-4k mark which after doing the plug, leads, and coil today has solved, although when i was coming home from my test drive it started missing when pulling away so need to check my work tomorrow as the engine was too hot to start sticking my hand near the exhausts and plugs.
