Idle issue

I changed injectors and fuel pump to walbro 255 car cranks right up now. But idle is off it goes up and down. Maybe vacuum leak. I've changed a few hoses. And fuel filter . Maybe bad sensor but no (ses) on. Any thoughts .

Did you re use the old plentium gasket or buy new? More then likely a vacuum leak or bad plentium gasket, had the same issue on an older one I had ended up being that gasket.

Same size injectors?

I had an idle problem before and took it on the highway and drove it like I stole it, idled back to normal after that

I agree on the gasket leak. They can be a bitch to find sometimes.

Can even be as simple as cleaning your throttle body and mass air meter. Might as well check your TPS voltage as well.

sounds like it needs to relearn how to idle. and also the IAC my need cleaning. if that doesnt work spray brake clean around the gaskets and vacuum lines and listen for idle change.
