f22a1 question

[THEONE]

a friend of mine has a prelude and ran a little nitrous on it.he ran twice with a 100 shot after the second shot the idle was awful,we found a burnt plug a bad wire and the cap and rotor were also bad. we replaced them and the motor still runs rough. the engine smooths out when you rev it. at idle it shakes.it does not smoke or knock. can anyone tell me what the deal is?oh and there is no check engine light on either.
