    97 Explorer EGR Excessive Flow Question

    it all depends on when you want the part. If you dig around online, and are willing to wait on shipping; you can find it a little cheeper than I paid. I compared Auto Zone, NAPA, and Advance. Auto Zone was the cheapest at 129 dollars. I wish it was cheaper, but that's what it ran me.

    97 Explorer EGR Excessive Flow Question

    Problem should be solved (for real this time) Alright, I pulled the EGR valvbe off and tried blowing into it. Air was coming out. Not alot of air, but enough that you could hear it. I tried to clean it up as best as I could, but it still was letting air through. Had to drive about 50 miles to...

    97 Explorer EGR Excessive Flow Question

    Yes the original code was P0402 and the new code that is on right now is a P0402 EGR Excessive Flow. When I had the EGR valve in my hand, the valve looked like it was closing completely. When the Explorer is just Idling in the driveway, there is no sputering or stalling like there's an Excessive...

    97 Explorer EGR Excessive Flow Question

    Ugh....I jumped the gun. I had the Explorer idling this morning in the driveway and the Check Engine came back on. I haven't got the code read yet. Looks like my Explorer is making a move sequel to the "Never Ending Story" and it's featuring my Check Engine Light. Mike

    97 Explorer EGR Excessive Flow Question

    I disconnected the negative battery terminal and let the explorer sit there. Then I connected everything back up and I've just put about 30 miles on it with no Check Engine light. Now, I know that the OBD system had to re-turn on after being off like that; but I'm assuming that 30 miles is...

    Found part of the problem Went and bought a hand vacuum pump to do the checks that both of you guys were suggesting. The EGR Valve is fine. It holds a vacuum and when opening the EGR while the engine is running, caused it to almost stall. Next, I checked out the EGR Position Sensor and it...

    Early Model 97 Ford Explorer XLT 5.0L Diagram Here's a diagram that I've drawn of my EGR system. These are located on the backside of the engine between the engine and the firewall and are a pain to get to, but not impossible. Tomorrow, I'll be pulling all of these parts and can attach actual...

    97 Explorer EGR Excessive Flow Question

    Here's some more information: The build date on my Explorer is July 1996. This means that it's one of the early model 5.0L engines for that year and they didn't come with a dpfe sensor. I crawled all over the engine looking for that rectangular box and never found it. On one of these forums...

    97 Explorer EGR Excessive Flow Question

    I have just bought a 97 Ford Explorer XLT 5.0 AWD that has 195000 miles. The check engine light is on and it had two fault codes. An O2 sensor fault (which I cleared by replacing the Downstream, Pasenger side sensor) and it also has a EGR Excessive flow fault. I took the EGR Vacuum Solenoid off...
