Did you clean your guidetube or replace with superceded part? If not, take it for a long ride...at least an hour or two. See if that does anything for you.
How long have you had the car...and do you monitor your oil/coolant level well? If not, do so, just in case.
As desperate as this sounds, in comedy, 'likes' and 'views,' 'friends,' and 'retweets' really help. If I've ever helped you, please help me by friending, liking, viewing, and retweeting. It makes others think I have a following...it'll take you a minute or less. If you could, I'd really appreciate it!
