its all good , i am just pulling my hair out trying to figure this out. I will try the EGR hose thing on it and see if it makes a difference. ill use a golf tee to clog it and tape and give it a drive. to see if it makes a difference.

I don't know the Zetec inside-out so I won't post anything.

Being a prick isn't rocket science either. Nor is trying to explain something yourself when there's a better source.

@OP: He's saying to remove the EGR valve from circulation.
In other words, follow this simple guide (this is for the DPFE sensor; The EGR valve is the large silver disc; Same concept):

If it's a vacuum leak: You can also use an open source of fuel (propane lighter, gas container with vapors escaping, etc).
If you pass over a vacuum, and it sucks it into the engine, you'll hear the engine rev up.

If you're going to try and remove the EGR valve from circulation, you might as well try to remove the DPFE sensor from circulation as well.
From everything I've read, there's a very little performance gain from it, at the cost of fuel (MPG). With one method, you have to deal with staring at the MIL.

Thanks , tomorrow i will try blocking the egr hose and see if it makes a difference in the driving . Someone also mentioned to check the hose that goes to the back of the intake manifold to see if it has collapsed . ALthough appaerintly the hose clamp from factory is a pain to deal with. will try and look at that tomorrow.

id rather not do a EGR delete , i will for testing purposes to see if its my EGR system or not , but emissions testing here is pretty strict so i won`t delete it. But i will try the above mentioned things and see if i get any change.

The issue is far to random for me to wrap my mind around it. in the past when a vaccum hose has a break it in or it is collapsed it tends to stay that way and have a constant. However due to the brake hardening up i still go back to the vaccum as its all vaccum based.

This may seem like an asinine statement: But have you checked the vacuum hose that goes behind the power box?
The brake booster that goes in the master cylinder? It's made of hard plastic I believe. But there's a different type substance it conjoins into.

when you say power box you mean the fuse box under the hood
or something else

I am pretty sure i looked that direction



You can see the master cylinder at the top all bright , i did have a look but i don`t recall seeing anything out of the ordinary.

If it's somehow not sealing, that would be a leak. It was just an idea that came to mind.
Yes. The fuse box under the hood. With all the relays in it.
