engine bay cleanup/vac line questions

[waggs187]

So i looked at the taboo vaccumm line diagram and I'll be using that for when I get my car set back up. My head will be back in about a week or two and I'm trying to get everything cleaned up the best I can before putting head back in.
What can do with all of the stuff at the top of engine bay?

Also can I do anything with this? It's just a huge chunk of wires.

Any help would be appreciated. Also there is a vaccumm solenoid thing up by the front passenger side of car. ( the vac lines go to the intake) Do I need those?


Thanks in advance!

I went through that first picture and labeled everything, you can remove some of it if your not worried about emissions or care about your A/C. That last picture you took are of your injector wires, I wouldn't remove any part of that huge chunk of wires if you ever want your car to start again.

Thank you very much! The A/C is staying because it will still be a daily driver for a little while. As far as the battery ground goes. I ordered the STM battery relocating kit that goes to the trunk. So more than likely that will be moved anyways? I heard it is a good idea to keep the solenoids connected so they don't throw codes. Is there a good place to relocate these? Thanks!

gofer its nice to see people take there time to help out !

I agree, he always goes out and beyond to help out

Yes keep the solenoids hooked up especially the one closest to the strut tower. This is your Fuel Pressure Solenoid. I would also recommened keeping the EGR Solenoid along with the EGR Valve itself. The main function of it is to lower combustion temps to prevent detonation. Since we have turbos this is very important. Hope this helps Also make sure that the vacuum diagram matches on your hood matches your final assembly. Mismatched hoses can make the car very angry

EGR valve is Exhaust Gas Recirculation which recirculates exhaust gases back into the intake which is supposed to help atomize fuel and also for emissions purposes. In my opinion very unecessary since exhaust gases are HOT and will raise intake temps. That is why most people remove them if they have leanant emissions in there state. Most fuel injected vehicles already atomize fuel very efficiently regardless. Someone correct me if I am wrong.

This is 100 % wrong. Go back to engine class.

sorry but this is true and thats way when i blocked off my egr valve i got better gas mileage.
so boreddsm you dont have to go back to class!

The FPS (fuel pressure solenoid) richens the fuel mixture on cold starts, since I live in California it didn't matter whether I had one or not. You live in Nebraska (I'm from Beatrice ) and its gets COLD AS HELL, I'd keep it on there for the long winters. But if you decide to remove it off the firewall just pull the extra vacuum line and run one vacuum line from your fuel pressure regulator (fpr) at the end of your fuel rail straight to a vacuum source on the intake manifold (IM).
The EGR (exhaust gas recirculation) recirculates unburnt gases back into the intake side of the motor at low speeds/low rpm to increase your cars fuel economy and emissions. Of course by doing this it gunks up the intake, throttle body, and intake valves in your motor... I'm not exactly sure how recirculating 800* exhaust gases back into your motor would lower combustion temps and decrease detonation? If that were the case I'd have 5 EGR's hanging off the back of my SMIM...

It is a good idea to keep the solenoids installed because more than likely you will see a CEL pop up on the dash. I run dsmlink so I can tell the ECU to ignore those pointless emissions sensors, its too bad I can't tell the emissions tester to ignore them as well.

I just did the egr/vacuum delete on my car and it surely did clean up quite a good bit, not to mention the car feels like it drives easier and smoother.
Good little mod for an $8 blockoff plate with gasket.

I have deleted my egr today and ditched the canister, it cleaned up the engine bay alot looks cleaner and seems like it idles smoother but maybe its mental

I wouldn't doubt it helped your idle, i'm sure out of all those old vacuum lines you yanked out there were a few crack and or broken ones causing the slightest of leaks.
I will update my profile engine pic later when i clean the engine bay up a little more. I also hid my solenoids behind the firewall so they're no viewable.
My buddy with a 97 talon ( chicken patty on here ) gained about 2-3 psi just from the egr delete !
His vacuums were so bad and cracked that it caused that much to be lost in holding boost.

I already removed the EGR and the Canister. I was just looking to cleanup that firewall a little bit. It seems so cluttered. I build my own computers and the wire thing bugs the heck out of me. I realize though that this is a car and will have a million more wires.

gofer--Thanks for all your help thus far. Last winter was terrible here. Over 3 feet of snow and freezing. You are lucky to be in Cali, except for the emissions stuff.

I will be running the Evo 8 ecu in my car. I'm putting the head back on to make sure she starts up and then I'll be putting in the evo ecu and MAF. I've got a project but....I just need more money! Time for a part time job ontop of my full time job. ! I still need exhaust, turbo, front mount, clutch. Ouch!

so does removing the EGR on a 420a work the same as removing it from the 4g63 ?
