Well since I blew up the transmission last summer and planned on pulling the motor w/ the trans. While the motor was out I decided it was a perfect time to do the rear main seal valve cover gaskets etc. I was looking at alternative Intake Manifolds for my engine and came across a K20A2 intake manifold. Swap it over to my motor and bought a Ktuned coolant block off/ bypass apdater. It all fit up as it’s supposed to. Also upgraded the injectors from 310cc to 550cc. Drop the motor and new trans back into the car. Started it back up and now the car is idling at 1500; which is normal at cold starts, but after being warmed up or at normal temperature the idle should taper off back down to 750. It does not; its stays at 1500 or when it get closer to operating temps rpms jump to 2000 rpm. My question is the new intake manifold cause the idle issues, bigger injectors, or both. There’s no vacuum leaks and can’t figure out why it’s idling so high. Any opinions or advice would be awesome!
