After two spark plug changes, using original bosch spark plugs(GM), I got engine misfires at low revs....????!!!!
Using NGK spark plug (a bit colder than the originals) the problem almost dissapeared!!!!!
Any Ideas??????

what do u mean colder? where they matched for your car?
try tightening them up a little (not too tight other wise they wont come out again), try pushing the lead on as far as it will go onto the plug, and before any of that u wanna adjust the gap exactly, get a feeler gauge from halford if u dont have one, the plugs are not set when they come out of the packet as they could be used of a number of cars

The gap is preset in all twin electrode vauxhall/bosch plugs!!
And I'am sure they are the correct reference!!!
K+N platinum spark plugs also worked great until I broke a valve at 138mph!!!!! (due to weak mixture)
This is really strange because it used to work well until that point
