my 99 se with 162,000 miles on it is sputtering like its going to stall at lights. I have replaced coils and plugs at nissan. it needs a knock sensor and i just replaced the front front o2 sensor what could be the problem?? please help me.

 

pleez help tonite it drove like **** and shudders while im drivin now then randomly drives nice again whats wrong with my car pleez help me!!!

 

probably clogged fuel filter, or even worse bad injector. let me know if you need an injector i ship them for $40 used, but in great condition

 

maybe your o2 sensor fuse check that..if its not that try replacing your rear o2 sensor...thats what my problem was and its sounds exactly like yours

 

clean your throttle body
