hello every one

I have a 90 civic with a DOHC ZC motor in it. Two nights ago i was driving down the street in 4th gear doing bout 60-65 km when i could feel almost like a slight bog or misfire while i was driving. Then i made a complete stop at a light when i was about to make a turn. As i put it in 1st gear and began to move i heard a loud pop sound that came out of my exhaust. SO i pulled into a parking lot. As i sat there i gave it a rev up to bout 2500 rpm and then there was another loud pop. And then the car shut off.and i havent been able to get it started since. I have recently put a distributor in. But i am not sure of the problem. I am thinking possibly a faulty fuel injector thats leaking fuel into the commbustion chamber causing it to detonate. The oil looks very fouled at the moment.(It wasnt like that before this problem) IF i booast the vehicle i may get it to start.but it is not drivable .i would put my foot on the gas and then i would get a loud pop.or it would just shut off...
anybody have any ideas..?.please help..
