I've attatched the pages from the Helms manual for those procedures. If you still have the problem after doing both of these, it's most likely a bad IACV. Oh, and since this is a VTEC engine use the idle numbers that the Helms says for the B17A1. This is my '93 manual so that was the VTEC engine that year.
Really appreciate your help. I will check that asap. Noticed your located in Rockville, MD. Im actually in MD also, Silver Spring. Im thinking of taking my car to Tischer Acura, just to make sure me and my friend have hooked up everything properly. Just wondering if you knew anything about this dealer. Anyways, i'll definantly check out that IACV and let u know. Thanks again.
