ok i bought a wrecked altima to work on since i hav a parts altima. now the wrecked 1 ran and my parts 1 dont. so i put a WAI and a fuel pressure regulator on it and a 300z fuel filter, when i started it it idled at about 1,600 rpm, then about 4 sec later it dropped and acted like it was out of gas so i went and got a gas can and put gas in it. tried again same thing. so i tried takin the fuel pressure regulator off. tried starting it and it did the same thing. so i put the fuel filter from my parts altima on it and it is still doin the same thing.

so im not sure wat to do. i know its not the 300z fuel filter or the regulator so wat could it be. considering it was running before i did this???????????

swap maf's and then the distributors if it doesnt help the problem. free fix if you still have those parts... i would also look for vacuum leaks. high idles or sketchy idles can be caused by simple vacuum leaks.
