1996 302.

Smog pump removed, all vacuum lines removed, Head ports for smog pipe(one each side) are plugged with 9/16" bolt. Exhaust pipe/system, directly behind catconv, smog pump port plugged.

I deleted the vacuum reservoir canister as well.

From the vacuum tree on the intake, i have one dedicated line for the HVAC, one for the fuel PSI regulator.

The EGR valve is ran by vacuum but it goes thru a solenoid first, so I ran a line from the vacuum tree on intake to the solenoid, then a line comes off the top of solenoid to the EGR valve itself.

I have also plugged the valve cover breather that recycles back thru the intake tube, Idk if that would cause something, I put a open element breather on the oil spout instead, maybe I'll reverse this setup tomorrow and see if it helps anything.

While the upper intake was off, I replaced the EGR tube(mine was broken, Ford dealer was $130 just for the tube.) Replaced the TPS, IAC and EGR valve, all Motorcraft brand.

I know its a mess, it could be a thousand things, but it ran good with no miss before all the swapping(EGR leak would run rough sometimes), I just wonder if I got the EGR setup correct.

Thanks in advance.

The EGR solenoid is designed to run off of the vacuum reserve from the reservoir, not from the fluctuating vacuum of the engine. That could be a problem.

The TAD/TAB solenoids will throw a check engine light and may cause performance problems if you don't keep them plugged in and capped off with vacuum lines.

I can't tell if you are talking about the PCV valve that has a hose that runs into the intake manifold, or the spout coming off of the oil filler neck that has a hose that runs to the intake tube - either way both of those should be functional as they are essential parts of the crankcase ventilation system.

I put the valve cover hose(to intake tube) back on just now and put the oil cap back to stock. The oil cap was replaced with a open breather element like a carb car has(not a good idea, imo) cap deleted.

The Pass side PCV was not altered.

The TAB solenoids are plugged into the ECM, I will plug the port off asap, I wouldn't think it would matter.

The CEL came on but just for the Smog System when I took it for a ride.

I'll see if the driver side valve cover going back to original will fix the performance issue, post back later.

Thanks BLD.

They haven't used open breather oil caps in like 40 years.

Nope. Its still chugging. Only at light throttle. Idleing around is impossible now. SOB!!

I wonder if the vacuum reservoir is the cause, like BLD mentioned. How would one go about making one?

Is there a way to delete the EGR setup from the ECM? A Tune can delete it right?

Thanks in advance!!

It was to eliminate recycling the hot oily fumes from my engine back to the TB. It already has a PCV valve on the pass side, why do I need to recycle more crankcase?

Its a Federal out of control Gov't thing. They wanted all cars to recycle this instead of putting breathers on them. You know, we should be green and be taxed for carbon pollution while they have military bases in 180 Countries and fly planes, ships and humvees 24/7 with no mufflers, yes but you guys clean it up and pay a little more for the things you must have in life(I say f**k them.)

I have a spare tin foil hat if you'd like to borrow it.



Engines used to spit the oil on the ground. Not exactly environmentally friendly. While I don't agree with some pollution control devices that is one I consider necessary. If it's causing running problems for you then it's time for a rebuild.

I plugged the TAB solenoids just in case it was drawing air and throwing off the fuel map but no luck so far.

It did seem to go slow a little easier, it was a short drive and maybe I havent given it enough time to recalibrate, while parked the idle was doing its walk thru(IAC sensor.)

-----Im gonna source a Vac Res asap just in case and see what happens.----------

Sean, there is no such thing as "tin foil." Its aluminum foil, we used to have to use it on our radios(foil halo) to get the good radio stations that tell you how to quit paying employment taxation etc. Sheep sh** news/radio doesn't tell you the good stuff.

Its unnecessary, Mercedes Benz's don't come with that garbage all over it. Its extra stuff to break and cause engine failure quicker. It would be a vapor oil(air pollution), not actual drops hitting the ground.

I'm not talking about aluminum foil. I'm talking about tin foil. The government conspirators are trying to keep it secret because they know we're making hats out of it.

Aluminum foil isn't getting me those radio stations. I have to get that stuff from YouTube. No state project.

Mercedes' do have pollution control crap, supposedly the Germans do it better. That's what my Volkswagen loving brother says anyways. I'm not a tree hugging hippy, but I also don't have tire fires in my backyard. Burning crankcase gases isn't hurting your engine, and using an open air breather does spit oil on the ground. Temporarily bypassing it to eliminate it as your problem, cool. You hooked it back up, thank you. I don't like all the pollution control crap either but that is one that even I wouldn't get rid of.

As far as your problem, you're a bit unclear. Deleting the TAB and TAD can cause the cat to clog but if you just did that it shouldn't be clogged already. You will have to hollow out or delete the cat before that happens. If you leave the solenoids but cap the vacuum out of them the computer will think they're still working and you can eliminate the check engine light.
