I am in the process of building my GN. I've done all Spring Cleaning and tuning with an Auto X-Ray until I get my Scanmaster. When I first go to start up my car, it seems to crank for longer than it should. When it does start, it smells of gas pretty bad. Driving at WOT it can smell pretty bad too. O2s are at low 900's to high 900's. I have used three chips (stock, Thrasher and RA) and all of them do this. I have my FP set at 43-45 line off. Stock injectors, but my FP gauge shows that they hold pressure after I shut the car down. It will hold at 40psi (line on) for 25-30 min after I shut off the car and very slowly decreases from there. The gas smell isn't horrible, but I feel like I've gone back in time and I'm driving my old GTO with 3 dueces. I've checked to make sure that my FP gauge isn't leaking the fuel (screwed into my Schrader valve). Any ideas? I've heard a cracked DS header may do it. How hard is it to get off the DS header? Sometimes it's like the car almost backfires during cranking while starting up (happened 2-3 times in the past month or so). Thanks!
