ok my new fc is a 88 the motor was change at some point dont know when.
all the emishions have ben taken off this car and i dont have them.
I think the motor swap is out of an S5. here is why.

The car has a 2.5in stainless exhoust costum welded. it uses pacesetter headers a muffle for presilencer and 2 pacesetter silenced fart cannons. "no i did not plan this echoust"

The guy said it didnt have enugh back presure to open them. upon furhter looking when i got it home there was a vac line runing from the back silinoid that opens it this is hte one by the firewall. i blew into it and the acuator went down. this makes me think it was to run off of a air pump leading towrds a S5 motor. the other acuator in the front however does not have this line and even upon pushing with my finger i can not get it to go down.

so whats your imput? S5 motor? seasid acuator?

its an s4. your going to need to search for "cleaning 5/6 ports" to get them to move freely. and also a good way to get them to open without back pressure. the easiest way i know of is to hook a hose to each one and connect them with a T. then run a hose from the T to your ACV outlet( check the picture, the hose will be attached to the thing with the yellow circle around it. then the hose runs all the way out to the headlight)

nevermind the red circle. its a pretty long job getting the 5/6 ports out to clean them so make sure you read up so you know what your doing.
