5.0 EGR question
 

I have the vacuum diagrams for the 5.0 and the EGR vacuum line comes from the Emission Vacuum Regulator (EVR) that I have not been able to locate but, I think it is no longer in the engine compartment because I removed the air pump and all emission stuff (but I could be wrong, let me know where it is and what it looks like if you can help).

So, my question is: Can I bypass the EVR and just run a vacuum line from the intake to the EGR or should I just plug the EGR up. I don't think the plugging idea is good but, give me your opinions. Should I find the EVR and place it back in the loop? Does anybody have a pic of what it looks like and where it could be?

Also, does anybody know what an FPR is? There is one line that is run to the FPR, but there is no FPR in abbreviations and I can't seem to find anything that resembles an FPR but of course there is a vacuum line that runs in the fender of the Mark VII and I think that could be it, so I am going to neglect it and just run my brake booster to the vacuum spot that was meant for the FPR. If anybody thinks this is a bad idea, please let me know.

Since you dumped the rest of your smog gear, it doesn't sound like you have to pass an inspection, so just plug the vacuum actuator line for the EGR so that it stays closed. It would idle like shiite if you hooked it to intake vacuum.

WTF is an FPR and where are you getting this stuff?

If you go to your local library they should be registered to Mitchell's AutoRepair and you can type in exact make, model and year of the vehicle and get any diagram, figure, or information that you want. This is the vacuum diagram for an 87 Lincoln Mark VII. The diagrams are just from Ford that are recorded and provided to the public through a healthy fee by your library. They have the Ford tag and everything on 'em.

The thing is, the EGR has a electrical connection to it and if there is no vacuum or anything on it, will it still operate properly and give the computer the correct data?

On my '89 'stang engine, the EGR is connected to a vacuum valve solenoid (controlled by the computer), which is connected to the main vacuum manifold.

FPR = Fuel Pressure Regulator. This is located on the intake fuel rail, and has a single vacuum port. On mine, it's connected to a port on the underside of the upper intake manifold.

FWIW, lack of the egr can cause partial throttle detonation at high load conditions (highway speeds going up a hill, etc) - the computer expects that mixture of exhaust gases to be there. No reason not to run it, IMHO.

Thanks guys. I actually figured it out yesterday when I looked over at my wiring harness and saw the two solenoids (it was attached to the harness because it has electrical connections on it), but that is why I couldn't find it before-- not in the Jeep on the engine and not in the Lincoln. Everything is back together OEM style, but without air pump and smog stuff.

All that is left is the wiring, which I think I have figured it out. That is until I go to start it and nothing happens or I blow up.
