My car is having idle,and power loss issues,i've checked all vacccumes,conections,egr valve,replaced the plugs,and the check engin light has never came on,but...right before this happend,i did have to help charge my girlfriends car with jumper cables,my next step was to check into the o2 sensors,but my car has 4 @$150.00 each,anything else i can do?

An O2 sensor will set the check engine light. Have you checked to make sure the catylatic converter isn't plugging?
