Hi all i got a little problem with my car when the car gets warm it starts to like missfire between 1.5k 2k revs. after that it is fine goes up the full range of revs. I have changed leads and spark plugs had it plugged into tech2 by a vauxhall mech with no faults found. But if i flip the throttle b4 pulling away it is sort of ok so could it be the throttle position sensor it doesn't do it all the time. Help on this would be most appriciated.

Car has done 76k on a '98 S reg.

Mine was running if started from hot (cleared up after a minute) when the tappets were rattling. I changed the oil and the tappet noise and lumpyness stopped 200 miles later. might just be a coincidence tho.
