- 2005 Explorer SLT
Good morning,
Over the last month 1/2 I have been dealing with the "rough engine/shake at idle" issue that many others on here have posted about. I bought this 2005 Explorer from my aunt after my uncle passed last October. It has 118,000 on it now. I want to layout what I have all done thus far and then see if anyone has any ideas moving forward to get this resolved.
1. Replaced Air Filter
2. Cleaned the MAF (also ran truck with it unplugged and the issue was there, just a little worse.
3. Cleaned the throttle body until it looked like a new one.
4. Plugs and wires
5. Fuel Filter
After all of these things (which had never been done so they all really needed to be done anyways) I was still having this issue. Then I found the post about having Ford flash the ECU with an update. Thinking this might fix it I went ahead and had that done. It did bring the idle up to around 700-740 (it was at 600-615 previously) it didn't fix the engine shake at idle, and actually made the shake even more noticeable.
6. Flash ECU
Finally I took the Ex to a very reputable shop that I have had alot of other work done at. They proceeded to diagnose the problem like I hadn't done anything yet. Once they got to the smoke test I admit I was hoping this would be where we figured it out, but they couldn't find any leaks anywhere, except from the EGR valve which they mentioned is somewhat normal, but he would continue checking. After looking at fuel trims and everything else (one of the banks was running a bit lean) he tested the EGR valve from the tool. He would slowly open it up 10% at a time at idle, watching to see if the value changed. It didn't change until 50%, which is where the engine really started to run rough. He was fairly confident that it was the EGR that was causing the issue, so much so that he said he wouldn't charge me for the 3 hour diagnosis if that didn't fix it. Well 2 days later I replaced the EGR valve and no change at all!
7. EGR Valve
So this brings me to where I am now. I have no idea where to go next and am sick of throwing parts at it (even though most of the items above needed to be done).
I am hoping someone on here can point me in the right direction to fix this issue!
Thanks,
Curt
