ok i have a jdm gsr in my crx running off a p72. it is lacking power and the only code i have is 23 knock sensor. in low rpms when you give it a bit of gas it stalls till around 3000 vtec kicks in right at 4500 and i can see iab open when i rev it from under the hood and its runs smooth at idle. so my question is can a knock sensor make my car run so slow and stall
