Kinda weird to read that you let your car sit. I did too before I had the idle problem. Except mine only sat for a month but I would start it up at least once a week for good will. Glad to hear you fixed your problem.

I have a couple ?'s for you:
1) what is a TB and what is an IM?
2) What exactly did you do to fill the gasket gap? I ll do the same if it'll let me drive the car around.
3) Have you had any side effects since repairing the gasket?

Thanks in advance for any advice you can give me!
