| Get your throttle bodys fixed. Make sure they open and close correctly and in sync. You want to make sure they are fully closed when off the thottle and make sure there is no oil gunk or something clogging them up or making them not seal properly. You want to set the TPS correctly so that the ECU knows the thottle bodies are open or closed so that the IACV can do what it needs to so that you idle right. May need to adjust the set screw on the IACV as well so you sit at the correct RPM. CAS cannot be at 25-30 degrees, that is bad. You need to make sure that the timing light sees 15 degrees AS WELL AS the ECU. The ECU will only give you the right number if you are idling correctly according to the FSM! Look in the FAQ or SEARCH on the site to find detailed procedures on what I listed. If the car is still hesitating after you correct those issures look up " Why does my Z hesitate sometimes?" in the FAQ for other alternative testing.
