When in low revs (between 1250rpm and 3500rpm if i put my foot down the engine miss fires ALOT, but after about 3500rpm it doesnt do it at all  .
Is this just simply because my engine is fooked after getting ragged everywhere or could it be something else?

Ive changed spark plugs, recently bought some magnecore leads aswell. Unless the magnecore leads are the trouble?

Coolant is fine, had to replace the lower coolant hose because the clutch cable had worn through it but after that never lost any coolant.

maybe not then. Get GM leads/plugs. Make sure the gaps on the plugs are right

does it hesitate if idling when you put your foot on accelerator?as if pulling away from a junction does it want to stall?

Well it sometimes wont even start without my foot on the accelerator and it does sometimes want to stall hence having to dip clutch and give it more revs . . . . . . . . . basically anoying everyone around me

Not actually sure to be honest, I think its worse when cold but can still do it when its warm. I only replaced my HT leads because my OE ones were knackered. I shall get my mate to get me some new ones (lucky bugger gets like 30% off retail )

maybe compressions. i would be checking them. it will be ok on the higher revs because pistons are moving faster and hence more compression. would also be bad starting from cold. does it seem to turn over fast when it wont start?

Not a clue, engine was replaced with an XE a few months after the topic was made
