2002 outback 2.5L AT 153000 miles. Bought used in december with 141000 miles. delivery driver. Water pump replaced 2 months ago. Last night battery
died, so replaced with ever start from walmart. Noticed coolant overflow reservoir was empty, so filled with 50/50 mix. Installed battery, filled coolant, turned key, car fires right up. Few minutes later at a stop light notice rough idle. Finish shift with blinking check engine light. Turning ac on while idling causes rpm to drop under 500 and act like it will stall. Help please?
JA: Is the car in "Park" or "Neutral?" Do you know if your car has a "wheel lock" feature?
Customer: This is with car in park and drive. I believe it does have wheel lock.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Tried opening cold radiator and running car to burp air from cooling system, no change. Still rough idle under 1000 rpm, almost sounds like misfire
JA: Anything else you think the mechanic should know?
Customer: Runs fine above 1000 rpm, no noticeable hesitation in acceleration, exhaust smells weird
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Subaru Mechanic about your situation and then connect you two.
