Is the check engine light on?, if it is take it to ur local auto parts store and they can check for codes free of charge

no, no check engine light. I just had it at my mechanic, who I trust completely. They were stumped. What would your next move be?


another mech. or technician ?, vacuum leaks ? clean the iac port ?
