Well you can start by the obvious disconnected hose and if you don't find any loose fittings or loose hoses, then you have to pull off the black flex loom and look for cracks. Sometimes finding vac leaks are a pain in the butt. But if you are getting all these codes from a leak it's probably gonna be a big one. maybe even your intake manifold gasket is leaking. or the seal between the egr or throttle body. Vacuum leaks can come from alot of places. I know that doesn't help alot, but it's just a time consuming process. if you take a piece of like 1/2" tubing and put one end up to your ear and use the other to probe around fittings and hoses, you can usually hear a hiss. Or you can buy one of those mechanics stethescopes, but some cheap old rubber hose works about the same.
If I can even find it.... This will be enough to stab myself in the neck with a fork!!!! BLAH!!!! Well its worth a try... My mils worked... And I get all these other probs... What I dont understand is... With the O2 sensor... I replaced it and light came back with code so I put another one on... I will check it out today or tomarrow I hope! If it is a vacuum line will ford have one of them?
I hear a weird noise.... Like moarse code like thing... It sounds like its coming from the middle of the passnger side around the head to the rear of the head any idea???
What do you mean by " like morse code"? Is it a whistling sound or a ticking sound? If it's a whistling sound like escaping air, then it's probably a vacuum leak or a leaky gasket. If it's a ticking sound its your valvetrain or fuel injectors.
I unplugged EGR sensor and the DPFE sensor and another sensor which has two bigger lines connected to it and the plug is similiar to an o2 plug in its located behind the motor in the middle behing and when I unplugged these the motor did nothing different... Little weird...
more of a tick... but it maybe the fuel injectors... Sounds like it could be near them... Can i unplug them when it is running??? has 114,000 miles... And I got another motor jus waiting to get it in... like one injector at a time... wouldnt that tell me if it was it...
Fuel injectors were replaced at 55,000 miles though... It was under warranty when i bought it... They replaced them and the plastic intake manifold... Had to go to the shop two times...
Oh yeah... I unplugged every vacuum hose to check for pressure!!! and only found one showing very very little pressure... The small one that connects to egr to egr sensor... i took off both ends and little pressure...
I wouldn't unplug your injectors with the car running. It will just dump alot of unburned fuel into your exhaust and foul up your o2 sensors. You fuel injectors are supposed to click a little anyways, that's just what they do. The vacuum line going to the egr valve itself shouldn't be as strong as the others. It's regulated by egr regulator valve it's plugged into. that little canister that the short line that goes into the egr valve itself is plugged into, bleeds the vacuum pressure off so that the egr is only on when it's supposed to be. so that's normal to.
If your putting in a new motor, then why worry about this stuff anyway. Your car should still run fine with the egr glitching. Just deal with the light. I had some problems with mine a while back and I unhooked the egr valve and plugged the line until I got it fixed. You can't even tell a difference and I never even got a CEL with it unplugged.
I would if it wasnt for emissions.... I was dealing with it... I cant pass em... Meaning I am not inspected... IT SUCKS!!!!!!!! Thats why im trying to fix it...
Will having that problem with the charcoal canister cause a bad idle? Mine sure is getting worse and worse. Its almost like it has a mild cam in it. (err cams) Got new wires, and plugs. Fuel filter is fairly new. Its never idled very smooth, but its worse now. I've gotten "multiple cylinder misfire" before and everything. Something is for sure wrong. I hear ticking on my car too. pisses me off. I think next oil change im gonna do an engine flush
They gave me some sort of valve which is in the engine compartment i didnt take off my wheel... It was tight in there... Has a rubber covering on it... CX-1158
