hi, i dont know why my integra started to idle really low, like 500 then it jumps up to 6 or 7 real fast and goes back to 500. im thinking that it could be my cap and rotor that needs to be replaced, but i could be wrong. so if anybody know the problem please help me out. Any feedback will be appreciated. thanks

 

if it jumps up and down...... its your vacuum lines

check all rubber hoses and make sure theyre not cracked
