The jumping idle could be due to the iac differences(switch ecu) or a vaccum leak, listen and spray around the tb and im for leaks.

your idle jumps most likely due to the throttle position sensor being set incorrectly (or left at the setting of the k8)You will need to adjust the tps and idle settings. Lots of people say no dont do this, as does the manual. But they are not taking into consideration that you have swapped the engine.you will have to look in the online shop manual jeff has provided for the details on how to do this.hope this helps ya
