96 lx body with 85 d15b7 engine idle problems
 

I have been trying so hard to fix this. I'm running a y7 manifold and TB having idle issues that relate to iac issues I have the stock d15b7 intake and TB. But I heard it wont work from the dude I got the car from...he says I gotta go d16y8 intake to fix my rich running. What to do what to do. I don't believe him what y'all think
