For some reason my car is only getting 200 miles on a full tank of gas. I have changed the oil and oil filter every 3000 miles, I have also changed the spark plugs to NGK. I have an AEM CAI and an exhaust. Both of the local dealerships dont know what the problem is. Plus my car has been having problems starting lately. There are only 35,600 some miles on my car. Any help would be great. :werd:
