i recently swapped my b20 into my da 91 and ive had a lot of problems with it but i finally can drive it. as the title says my idle is wierd. its at about 2k and the onlything i can think of is a leaking hose or timing off, but i did not mess with my timing at all and if i retard my dizzy so it idles low then my car just shuts off when i turn the ac on . now heres my conclusion . on the IACV theres those 3 little screws on the bottom where the line goes in , well one of them broke off so i just used some vice grips to get the rest out but i don have the screw and i dont know where to get it , could this be the reason it idles so high , anti freeze does drip out very slowly.....any conclusions?

 

bump!!! need to atleast get a lead so i can work on itsin the morning b4 work
