so what can i take out of my engine bay relating to smog and egr?

heads are pluged.no air pump

which vacuum lines can go?
does the carcoal canistor go?
what about the 2 plastic things on passengers side fender well?
what do i do with the piece intween the intake and tb?
is there any thing i take out on the passemgers side in the engine bay?

is there anything else that is useless and can go?

The steel tube going from the mid pipe to the smog system can go. Everything next to the exhaust manifold(rubber hoses and steel objects) can be removed.

You can either buy/make a plate that will cover the hole in the EGR spacer on the intake manifold after removing the EGR hardware. Or you can buy an EGR spacer without the hole. The reason you need an EGR spacer(with or without EGR) is because it has the bolt holes for the throttle cable bracket. If you can manage to reroute the throttle cable/speed control (cruise control) cable you can eliminate the EGR spacer completely.

All of the EGR system is fed off of a vacuum line at the upper intake(maybe it is at the vac tree(too many beers)). But when you cap the source of the vacuum(the engine) you will have no vacuum leaks by removing the EGR.

By removing(unplugging) the EGR apparatus that is bolted to the EGR spacer in the intake, you will get a check engine light. You can eliminate this light by either using resistors or buying a plug in connector that is essentially resistors inside a plastic connector. This will eliminate the check engine light, but will result in a code saying the EGR is closed.

By the way, the two plastic items on the passenger side strut tower are the Thermactor and Thermastor solenoids. They can both go.

any idea where they sell these block off plates and the plug in resistor?

ponyboy88

and when you say it will eliminate the check engine light, is that only the light from the egr code or are you essentially disabling the check engine light altogether.

I picked up the block off plate for the stock EGR spacer from a company called RJMInjection. I also got the connector from them.

All of the EGR delete crap is on this page. The bolts that came with my EGR block off plate didn't thread into the stock EGR spacer, so I had to reuse the stock EGR bolts.

One thing to note... sn95 owners bitch about the eliminator not working, that's because this is designed for FOX 5.0's.

When you use the eliminator or resistors and plug them into the stock EGR connector in the wiring harness, the electric signal that gets sent back is telling the computer that the EGR is closed. At full throttle the EGR is closed... which is why the EGR doesn't affect performance. There will be the code saying EGR is closed, but it does not throw a check engine light. If it did... everytime you're at WOT the check engine light would come on.

If you leave the connector unplugged, the check engine light comes on because it is not the EGR closed code, but rather an EGR malfunction.

thanks. The guy who works for RJM is on another forum i am on (fullsizebronco.com), good guy and i should have guessed he'd have something like that.

so all 3 solenoids can go? do i just leave the plugs hang then?

also if i go the resistor route for the egr how do i do it?

86 5.0Lmustang

anybody?

Yep. Mine are danglin'. I just burnt a chip that solely eliminates the EGR and Thermactor codes so my check-e lite isn't always on, so I don't know about the resistor.
