Hey guys i just installed my ottp stage 2 kit, now i checked everything, made sure that nothing leaks and it went smooth, now i started the car and evertime i rev the car a little hard it bogs badly, and when i drive like at around 3500 rpm it does a lil hesitation then goes back to normal, but it only happens once in a blue. And it did throw a check engine light at me but when i went to check it at my job ( i work at napa) it seems like my plug/connector in my car does not work so i dont know what it is...... Any input would help guys.

Thanks
