Plz Help! Bucking at partial throttle!
Hey i have a JDM RR swapped 96 200sx se. When under partial throttle, ie leaving stoplights or pulling out of drive way, sometimes the car will bog and missfire the start bucking until i hit the clutch. Also on startup sometimes it will immediately bog down to 500 or so RPM and sputter until it tap the gas then it idles. I also smell raw fuel from when either one of these problems occur which leads me to believe im running rich. my question is why? I would like to think i have a bad tps, O2 sensor, or maybe even maf? what do you guys think? Thanks!
