Well let me break it down, im new to the nissan world, i've tried searching for answers, but if i am repeating already answered questions, please
kindly point me in the right direction. I just recently purchased an S13 coupe, KA24DE, she ran fine when i got her, she started acting up one day after i took her to the car wash and hasn't got any better. The symptoms are; poor idle, when i go full throttle she bogs and slowly increases in rpm's, but if i hold the throttle 1/4 way it'll sputter and run up the rpm's a little faster. I did run my ecu for codes, got a code 12 (air velocity sensor) so i changed the MAF sensor, didn't help

. I just want some help before i throw more money at someting that doesn't need replaced. I am mechanically inclined, but i haven't worked on any cars with computers

, and now im remembering why, haha jk, but im trying to learn so bear with me. The reason i got this car is because my friend has one, and after i drove his i new i had to have one

, so much fun to drive....when they're running right! So one nissan lover to another, please help me!
