ok we are running into some problems.

we think its the wiring harness.

i am using the harness that came with the swap which i think is a SI harness.

but the car is throwing mad engine codes and just won't run right.

EVERYTHING is plugged in right nothing is missing or anything.

but the car just won't run right.

any suggestions.

 

there might be a short in your harness bro, that or change your o2 sensors

 

by the way i have a hf also with a b16, just recheck your wiring, but most likely theres a short, try unhooking your reverse light wires next the tranny, i unpluuged mine and my check engine light went off... i have a short in my harness also but my car runs good

 

dont use the b16 harness. use your cars harness. Ryan

 

aite there is no spark thats one of the problems.

 

its throwing a air sensor something error and engine coolant error.

we check everything and it looks fine....we are starting to think that the harness might be bad.....and i don't have my old harness long story but its not there........anyone got a 88hf harness?

 

The HF stock harness is a little different than the other ones, and you need to cut certain wires for it to work right. I have an HF, and I would always get the coolant sensor CEL, until I unplugged my reverse light connectors. The I found out you have to cut a wire right before it gets to the ecu, in order for it not to throw the coolant CEL. I cut the wire, and re-connected my reverse light wires, and it has worked ever since. Do a search on here about that and you will find more info on it. Also, that's the only wire I had to cut, my shop did the rest of the wiring.
