OK.. I got myself a P-90 head from a salvage yard and stuck it on my '83 non-turbo 280zx .. Now once it is all back together I am getting some bad smoke out the tailpipe.. At idle it is very visible and when you give it gas, it is smog city behind and around the car. I was wondering what may be causing this. I believe it was smokin a bit before the head change also.
The sensor light is on on the digital dash also, and I have no idea what to check/change. Any ideas on either of these problems with be appreciated.
