well bought a car for 600 bux a weeke ago. It was runs good. its a 95LX d15 16valve. only has 113,000 miles on it. thought id do a plug,wire ,cap, rotor and oil change since its probably never been done. some plugs were a little seized but they all eventually came out. everything was done last night and i started it up and let it run for lil, started up without any hesitation then i backed it out and parked. went out this morning started it up fine and drove up the street and after about an 8th of mile it shut off. Any thoughts? it cranks fine and sounds like its firing corret. a fouled plug maybe? i used ngk plugs before and never had a problem. the gaps were all good from ngk aswell. never had a problem with anything on it at all. what could i check to cancel things out first?
