Heres my problem. I installed a vafc on my 01 gsr and decided it wasnt for me and took it out. Since its removal my car acts really weird at partial throttle. It only happens when im cruising with the gas constant. the car will start to bog and pick back up continuously untill i give it a little gas and then it goes away. Any idea what would cause this. Only thing i can think of is a bad tps sensor. Ive replaced the plug wires & the cap is good. I also checked the injectors and fueal pressure. they all seem to be good has to be something with the air delivery system right. Any input is helpful
