Well my integra ls 97 is not acting right. If its just parked and sitting there on it will stay at about 500 rpm and then will go up to 1000 and drop almost to zero and then go back up and do the same. When im driving i hit the gas and it doesnt want to move and then after a little bit it will pick up and start moving again. Very wierd i dont know what to do anybody know what could be the issue ?
