k i put a gsr motor in my 99 ex used the stock ex harness what will it do with the iab switch left unplugged, will the butterflies open or be stuck closed any help is appreciated i am stumped

 

What ECU are you running? With stock GSR ecu, you will need to have that hooked up correctly or it will not open the intake secondaries and your motor will run like crap.

You can get a skunk2 intake manifold that doesn't require IAB valve, but you will need different ECU that doesn't look for it.

Here's a link for you that will probably clears up alot of your questions.
