2.8 / 2.9 V6 Tech | Forum profile

Not real fluent with the EGR systems, but the EVR will vent to the atmosphere when it's off. I suppose if there were still vacuum between that and the EGR valve, it could be possible, but 5 seconds seems like a lot of time for that to bleed off. Here is some more info on it - good site: http://www.fordfuelinjection.com/?p=43 Pete

okay so I wanna adjust them but dont really know how. Is it easier to have them adjusted or to do it myself. How much would it cost.

Thanks for the link. Lots of good info. I have studied it and that is the part I'm talking about. It says when the EVR is off both ports will vent slightly. I'm not sure what that means. Is venting the same as a vacuum leak? Does it mean that the vacuum port will loose vacuum when it is off? Is that what I'm hearing? Also this rig doesn't have the vss senor hooked up which tracks your speed and I have always wondered what...

It's a 2 minute test at your local auto parts store to confirm the alternator is failing.

What's the fuel pressure?

well, it would go back down, the pump kicks on to pressurize the system when you turn the key on, but if you don't crank the engine or start it, the pump shuts back down and the pressure bleeds off.

Quote: Posted by urhotmom i replaced it and still same problem i put fuel pressure guage on and it reads 20 up to 80 psi, when i cut off the return line it get about 100 psi, one other thing when i am checking fuel pressure it does not keep the pressure it goes up to 100 psi and then slowly leaks down. your FPR is bad... 2.9 Regulators are supposto kick out 29.9 PSI

just have the valves adjusted.

I'm running a 91 explorer AC Radiator and one thing i didn't grab was the fan scroud for the 4.0 radiator. get one. it makes a difference. i went threw two fan clutches before i realized the 2.9L scroud was too tall and was making the clutch work to h ard and burnt it up.
