Just finished s14 sr install, running very rich - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ok... I just put a s14 sr20det blacktop into my 89 240sx. It fires right up and will run. I got the timing set right in ( second mark from the right on the crank ). If I take the car for a drive it will kind of buck on me a little bit when not at WOT. When it's at WOT it pulls really hard. After I take the car for a ride (abou t a mile or two), it fouls the spark plugs out from running so rich. If I rev it, flames will shoot out. I went over all my wiring, and everything seems to be right in place, and all the grounds are hooked up. At first the MAF extension was held together with crip connectors, because I was all out of solder when I extended it... I soldered it today, but haven't tried new plugs yet, because I don't want to waste $30 again if that isn't the problem. I thought maybe the crimp connectors were causing to much resistance and causing the computer to think the engine was getting more air than it is. Do you have any other ideas as to why is it running so rich?

Thanks,
Jesse
