Hey guys just pulled my codes (first time doing it) and I believe I got a code 13. I did the test with the engine running and in neutral. It flashed one long one and then two quick ones and then it did one long and three shorts. So what is code 13, something 'bout not being able to idle or something huh? My car idles fair, but bucks and chugs at cruising speeds and the tc is not locking. Is this 13 I got related?
