Hey, I searched around and couldn't find any solutions so link me if this has already been covered.. I have a 91 CRX with a b16 swapped into it, picked it up not too long ago with the swap already done.

When I start the car the idle runs up and down between 900 and 1500 for about 10 minutes or more before finally settling down to around 1000, anyone have some pointers or have any of you had a similar problem?

Thanks
