good afternoon,

I have an 85 190 e 2.3 4v. the needle on the speedometer bounces quite a bit up until about 50mph (at which point it calms down and works quite well). Is tightening up the needle an option or is there a quick diagnosis/fix/likely thing to check?

One unrelated question, when the car is cold, for the first shift of the day from first to second, the car shifts back and forth in a studdering sort of way, first then second then first then second for good. This problem never happens when the car has been so much as driven around the block; it is only upon the very first shift of the day. What should I keep my eye open for here?

Thanks in advance,
CDT
