In my house!
:bang: right, ive done my tappets.....mmmmm sounds golden!! but ive still got quite a rough idle, shakes a bit like a v8 but stops when u rev it. tried inj cleaner etc and no joy, could i be overlooking summat like a dodgy engine mount? also whenits warmed right up my revs drop even when i got blower on a bit n stereo at normal levels but no alternator light comin on!

also got magnecors and new ngk plugs in other day, any ideas anyone?
 
sounds just like my car !! The logical steps would be a compression test (to make sure all cylinders are the same/or close) and then check that each plug is firing OK . On an mpi , a dodgy injector could cause lumpy running too.

Hi,
Try cleaning the idle control valve, give it a blast out with carb cleaner.. :)

Thanks
