Re: 87 Burb 4.8 swap
Right now I think things are not talking to each other correctly. I have one o2 sensor reading lean consistenly, which I guess could be an intake gasket or vac leak on that side. The other is reading slightly rich but neither are switching like I would expect them to.
Anyone have a data log of what 02 sensors and fuel trims are supposed to look like?
Thanks for the suggestion. Ill look into that too. I would expect that to cause rich readings.
