JA: Sometimes things that you think will be really complicated end up being easy to fix with a a car. The Mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?

Hi .My Name is ***** ***** i will be assisting you with this issue . You said the service engine light was flashing , Okay this is a sign that the engine is misfiring .this will cause the rough running engine that you are experiencing. The code you had, cooling fan malfunction is not related directly to your problem but could be indirectly the problem ,is the engine overheating ?if it is could be a cylinderhead gasket issue which will have to be tested to confirm this . The symptoms you gave point to a head gasket . Flashing service light is a misfire you should have a code like P0300 .I suggest you have the cylinder headgasket tested and have all systems checked for codes .If you can do this then please get back to me with any possible codes that maybe stored .
