Idle question on my 92 3.6

[Gregt909]

Hi guys,

Just picked up my (new to me) 92 C2 Cabriolet and noticed that right at start up the idle goes up and down several times, ranging from 1200 down to 400 or so before settling in at 800 or so after 5-10 seconds. After that it seems to idle fine. Is this normal? If not, what might be the culprit? The vehicle just had a lot of work done, complete reseal, immediate shaft bearing, major tune up, etc....

Appreciate any advise here. I'm sure I'll have many more questions for ya soon.
