ok i got it all taken care of, got the new plugs (gapped this time) and replaced cap and rotor (finally found one) and it runs a lot better now. but when i did the cap and rotor, inside the distributor on the little guard covering the "guts" it said p73. is it a type r distributor? the head is gsr, i know becasue it says p72. just thought it was a little weird, but oh well, whatever works right?, lol. and one more thing, im about to replace the fuel filter and the people at autozone said i should get a pcv valve too, so i did, 3 bucks isnt a big deal, but i dont know if i got the right one. i got it for the car, not the engine. should i have gotten it for the engine? where is the pcv valve located? my car is a 91 CRX si, engine is 94 B18C1. thanks.
