its a MY97, only really does it in 4th and 5th gear when on load, and when you come upto traffic lights/stopped the revs seem to dip away down then idle ok for 10secs then revs drop again, so on and so forht

Sounds like a Maf problem, not a misfire.

Misfire is stuttering under load.

Best not to do it, unless you know it's dirty, then use carb-cleaner sprayed on. Don't touch the thin wire.
