i have a 91 crx with a obd0 b16a. A few days ago my car started acting like it was running out of gas. i got to a gas station and turned the car off. after i got dont putting gas in the car wouldnt start. it was throwing like 4 or 5 differant codes but after i got the car to my house it stoped throwing codes. i started with the plugs and wires... 3 of the 4 spark plugs where fould( where replaced with new plugs and wires) and ther was alot of carbon build up. for some reason ther was some oil on them to. i dont how the oil would of got there... but i did find that 3 of the 8 valve cover bolts had come loose. anyway the next thing i could think of was maybe the timing was off. so i started to looking at my timing belt and relized that my timing was fine. i also have looked at the fuel system thinking that i wasnt getting fuel.. but its got fuel. the only thing i can think of is maybe the map sensor or maybe my tps sensor. itf its not the map or the tps i have no more ideas on what it could be. oh yeah i also just put a new intake manifold and 76mm throttle body on. maybe that has something to do with it not running.
