Right I bought this S13 with a CA18DET back in January, drove back from Scotland and it drove back alright apart from running very rich. Took it out a few weeks later and blew a boost pipe off so thought nothing of it, limped home and re fitted the pipe. Started the car up and now it's just misfiring ridiculously bad, smoking like **** out the exhaust and oil near enough pissing out the exhaust. Changed plugs and old ones were blacker than black. Car still runs like a bag of crap. Any ideas??! Bought a beemer now and have just lost any interest in this car completely but would like it running so I can sell it!
