My nx boggs out when i open the throttle fully, and engine dies when i come to a stop in nutural, i have to find that happy medium to be able to get up and go, i cant just step on the gas, if i do then it feels like im towin a parashute. i have no idea what it is, ive changed the plugs, wires, cap, rotor, fuel filter, ive cleaned the air filter put in a new (used but good) maf, but nothin....any ideas? i noticed a lot of people on here having the same/mild difference problem and either 30 different solutions or none.... im trying this step by step to figure it out on my own but would be nice to maybe be pointed in the right direction if its other then a fuel problem...THANKS

Have you checked the TPS?

i havent, ive heard adjusting it can be a pain thats why i havent yet....

Adjusting it would be fine tuning; I'm concerned that it might have failed.

nah, i have a spare nx that i take parts from im just a little lost when it comes to something like that,(checking/replacing)

did you try and check your injectors? i had sort of similar symptoms and turns out one of my injectors went bad. just unplug the harness off of each one while the vehicle is running and the engine should die out if the injector is actually working. if the engine idles the same as before the injector was unplugged, it's not working.

just something to try.

thanks, ya that was my project to do this weeked if this damn colorado snow goes away

enjecters wernt the problem, seems like a little timing isue.....

i had this same problem last week and stupidly threw in a new fuel pump. didnt fix it. a hard long inspection found that my vacuum line coming from my fuel regulator was cracked, fuel line from filter had a very small crack and my negative post connecter on the cable was little corroded. replaced the hose and line, fixed up the connection... problem solved. btw the crack on the fuel line was veeeery small

How many miles are on your car? I think grizz is leading you in the right direction. Check your vaccum and fuel lines carefully
