bogging help

[kouki3]

i have a 97 240 with the s14 blacktop swap. when i start my car it revs fine, but after a couple min of running it has a hard time reving from 0-2rpm. i think i might be pumping too much gas. what do you guys think? thanks

check you air filter and air flow

i think you have fuel problem.did you do the wiring yourself?check the fuel signal and ground.

pull your plugs and see what they tell you first.

i think it is my fuel. everytime i pull the plugs, they're black as hell and very wet. I sent my wiring to wiringspecialties.com. although i didn't send the ground.

I'd check over your TPS. If the ecu thinks it's at a higher throttle position, it'll dump more fuel assuming it's a problem across all 4 cylinders.
