hello people in the house. I really need help on my crx Si Sohc. I just did a swap on my d16 to a Sohc. got it running but still using the old d16 intake manifold and throttle body. but my idle is up to 1500 and it never go down. also my engine light won't go off. what's going here, is it the O2 sensor that os making my engine light go on?. did a engine test and it's giving me a code 9. I also installed a obx camshaft stage one on that Sohc.now my valve is ticking alot. what is the spec on the stock valve clearance for a Sohc d16?
