I'm sorry to say, but only hands on diagnostic testing can tell you the answer to your concerns. A diagnostic tool of high quality will be able to see any diagnostic trouble codes that are present in all control modules, then help pin pointing the source of those concerns. Something is actively failing -- which is good, because you should be able to see it more easily that way. www.repairpal.com/repair-shops
