I definately wont let AutoZone "fix" anything. I will just do what yall said and let them check the pressure. Ive already had some moron at PepBoys blow my engine b/c they forgot to tighten the coolant hose (they were only putting in a new battery???) I really thank yall because I do not know anything about engines. If the EC light means "economy" mode, then no it is not on. That is what I thought it might be at first. Yall are probably getting the biggest kick out of me not knowing what the hell I am talking about, everyone on this site seems to be very car-savy. Thanks & have a great weekend!
