When I check the codes I get a 44 which is a "battery temp sensor volts out of range." Other than this I just had it into the shop and they told me the valve cover gasket was slightly cracked. I've switched out the spark plugs because it was misfiring. It's a lot better now but still idles a little rough after running for a minute. I was wondering if the above mentioned problems could affect idle? What does batter temp sensor volts out of range mean? And how much could the cracked valve gasket cover be affecting all this? Thanks in advance.
