Ok I have a 91 CRX HF and I swapped a B16A into it. And a few weeks back I had one of my friends rewire the ecu to make it look alot better and to hook up some things the shop didnt hook up. Well now whenever I throw it in reverse it starts freaking out and dies in about 5 seconds and it throws code 6 for the engine coolant sensor. I have no clue how to fix this or anything so any help that I can get is wonderful. It is running a PR3 ecu OBD 0. thanks guys
