Well, we butchered he inspection. Emissions were like 10x higher then supposed to be. If anyone who has a 1990 F-150, or Bronco that could answer some questions, that would be awesome...

'90 4.9: What is this?

http://www.angelfire.com/mech/broncotx/index.html
This is a link to some pictures of thing I need help with.
This is a 1990 4.9 EFI engine.

Pic 1 is 3 vacuum control solenoids left one controls EGR right one is the air injector pump... so what is the middle one.

Pic 2 is air intake to the air injector pump. should it get cold air from under the car and is it ok to take in air from the engine compartment?

Pic 3 WHAT IS IT I have no idea .... where does it get air from and where should it be directing air to?

Thanks

I do not know how much help a pic of the vac line label would be. It is from a 351W Bronco engine, I think it is 1991 but that doesn't matter too much. The basics of the routing are there.
It is in my gallery Pam's Red.
