so i turn on my car and it sputters a little but on a constant.....i drive off and it sputters all the way up to the RPM scale.....i have no leaks in my intercooler pipes and the air/fuel gauges reads stoch. and a bit lean and i did install the walbro 255 fuel pump...can anyone help??

 

Are your plugs messed up from all the issues you have been having? Is your fuel filter clogged from contamination(spelling?)? are your sensor values corect? Do you have any loose grounds?

 

coilpack. swap a known good set and get back to me. are u running a narrowband or wideband o2 sensor.

 

i dont know the o2 sensor came with the engine....so you think one of my coil packs arent working ??

 

ECT?
still.

 

Sounds like a spark problem, recheck the gap on your spark plugs. Check the condition of the plugs as well, you could have burned them up from your previous problem. Maybe you didn't screw one or more plugs in all the way.

Maybe check your connections for your fuel pump too.

 

i checked the spark plugs and they ar gapped at .30 so they are aiigh...and they do have spark...any other suggestions ??

 

Trust me. Try swapping in a good set of coilpacks.

 

did that still same problem....havent checked my timing yet tho..

 

sr20.........lol i love nissan
