More Idle issues on my LC

[sebasti0n]

I just changed the Temp coolant sensor, which sorted out most of my starting problems.....

The LC was fine for the last couple of weeks, but i noticed the last couple of times that ive started the car, that the idle seems to flutter a lot and until the car warms up, when I come to a stop, the revs drop to around 500 rpm, then flies back up to a 1000 rpm, then settles to the normal setting....

Engine management light is not on...

anyone els experienced a similar problem and what was the solution ???

Thanks.

could try running with maf unlugged to elimate this as a starting point/

I had a problem with the idle on my lc so i decided to check the throtle body and found when i pushed it there was a lip of dirt and oil i cleaned it all out with carb cleaner and did a throtle reset and its fine now

Vac leak?

id say all those possibilities above are good ones to check.
let us know if you have tried the maf, throttle body, or pipe checks... and if it made any difference
