Changed plugs but still problems
Hi guys, i changed the plugs on sunday, there is a big difference it doesnt judder like it did before, but there are still a few problems. i have listed them below.
1. on tick over it miss-fires slightly
2. when i pull away its a bit lumpy and drops off a little
3. when i start the car it can be a bit difficult ( take 4-5 sec)
4. when changing gear it sometimes holds the revs quite high
5. there does seem to be a lack off power
Thanks David

You definitely need to take the rubber bits off, the ends of the coil packs can be cracked to bits under there. When I bought my '96 STI it had a slight misfire; bits actually fell off a couple of the coil packs when I took the rubber boots off them.
If you buy s/h coil packs, get the seller to remove the rubbers and inspect them for you - I made the mistake of buying a set described as OK, only to find that they were cracked under the rubbers too, and I had to embarrass the seller by asking for a refund.
With a good set of coil packs the misfire was cured completely.
