Emissions delete help!!

86whitevert · May 2, 2024

I watched a YouTube video on how to go about deleting emissions/egr stuff, and after I got done taking out the egr/smog solenoids I realized that my year of fox is different . This guy mentioned reusing the check valve on that big old vacuum line and plugging back into an elbow on the firewall, but I don’t have that elbow. Is it fine as is in the photo, or am I missing something? It’s an 86 5.0 .

The 'Utube' strikes again!
Go to veryuseful.com and look for emission vacuum diagram for your car, that should help you out,

It only gets me so far.. all the examples I can find are of other model years of stang that have different looking vacuum lines.

The problem with deleting those lines is the HVAC lines and vac reservoir for the HVAC is intermixed with them.

Your setup is a little bit different but it should mostly mimic the above. SInce I see you are deleting the EGR (which i think is more trouble than it's worth) you would be removing what is highlighted in yellow. What you should do instead is ID what is needed to route (after the blue check valve) to the vacuum reservior inside the pass fender, and then to the HVAC controls (vac line throgh the firewall where the EVAP core is). Everything else can come off.

Really no point deleting the charcoal canister (bottom right of diagram).

I tried to find some stuff on youtube or elsewhere on rerouting whatever is after the blue check valve, but the 86 model year seems to have slightly different vac lines. It seemed like what i was taking out was somehow completely seperate from the HVAC and vac reservoir? When I removed the smog and egr solenoids i tried tracing them back and they didnt connect back to the main vac stuff (I dont think)

Its worth mentioning that under normal cicrumstances i would totally leave it in place, but the car was delivered In half-tore apart form. i kinda wanted to save myself the hassle and just get rid of all the old crap thats half connected.

Ok I think we watched the same video. My car (90GT) was also different. I deleted my EGR years ago and had it tuned after. I recently just deleted the solenoids and extra vacuum lines so I think I can help you. I kept my AC lines along with the round vacuum reservoir in the fender. There should be a skinny vacuum line going into the passenger fender and that's the line to the round vacuum reservoir. The thicker line with two connections goes to another cylinder looking canister under the fender that was for the egr system which you don't need.

For those of you who got rid of your EGR system, did you tape up and tuck away or cut off the harness connectors that were attached to the solenoids on the passenger strut tower?

Mustang5L5 · Oct 17, 2024

Just left them unplug and tucked away. I would never cut any harness given the value of these harnesses these days.

Thanks, I ended up wrapping them in electrical tape and tucked them away.

May not be a [horrible] idea to label them so that you remember WTF you did.

I'm getting pretty good at the "What plugs are these" threads.
