I have a 98 teggy with a b20 swap and is currently running on a p75. It's causing me problems with running lean into my car so I went and got a b20 ecu (37820-P3F-L01) only to find out that the small plug on the side I need is all plastic and I can't plug it in. I'm sick of seeing my engine light on and am trying to find a way to get that code to stop coming up. I checked everything else and I'm pretty sure it's from the ecu, if not, I still want my teg to run better on the right ecu.
