So I have a 01 gsr swap in my 96 hatch and having a few probs. Hopefully some of you experienced swappers can help me. Here is a list of my parts.
01 gsr swap
97ex Harness
skunk2 intake manifold
Aem short ram intake
obd2a p72.
came with a 2plug distributor(maybe obd1) that we replugged to a 1 plug of my d16 dizzy.
Now here are my 2 problems. First I am getting a IACV code And do not know why. I replaced it with a new IAC valve and problem not fixed. Getting tired of the low Idle and cold stalls. Second My tach no longer works after the swap but I am hitting vtec so the ecu is getting a signal. Thanks

 

Did you connect the secondary butterfly because that might be what is throwing of the iac?

 

I have a skunk 2 intake. there are no secondary butterflies.

 

Is the 97 EX harness from an automatic? If so, the auto EX's have a 3 wire IACV like the DX/CX/LX and thw wiring will need repinned.

 

I bet that the tach problem has something to do with the b16 dizzy. Maybe the tach signal for the guage is a different pin?

 

I had thought of that. The tach worked on the d16 and the tach is out of a 99 b16 si. I am going to get a obd2 gsr dizzy with one plug not an obd1 with 2 plugs. I think I screwed up the wiring when I wired it before.
