Ok this is my problem PLEASE if anyone has had this problem tell me what it is! Ok I start up my car -92, 2.3 DOHC Prelude not V-Tec with 142k. Let it idle, It runs alright untill it gets to operateing temp. and then it starts to smoke a little and if i give it gass it smokes alot and while idleing or driveing slow it miss fires on the second piston, but if im going like 30 or above its fine? I replaced my spark plugs/wires/cap/ and rotor. I am about to take it in to get a test run on it to see whats wrong with it? unless somone in here can tell me? Please help me!
