I have a 2006 Explorer 4.0 and have had it in twice in the last week for the whistling. They are stumped at this point and have changed the tensioner and pulley but not the problem. The whistling starts at 2000 rpm, peaks at 2250 but can still be heard at 3 and it doesn't matter what speed you are at as long as your are in the acceleration mode. According to my brother in law who works for Chevy they had the same problem are have just been notified that they need to replace the throttle body. Hope that is it and that Ford recognizes it if it is the same. So far I have passed on the informtion to my dealer rep but am waiting on their solution to the problem.

2006 4.0 engine with whistling noise. Starts when accelerating and getting up between 2-3000 rpm. Have had it to the dealer twice of which they have also duplicated the problem in the bay and they originally changed the pulley and tensioner (not the problem) and now are looking into the area of the EGR. Ford (as of yesterday) doesn't seem to have any mention of any kind of this problem . Chevy on the other hand just issued a notice for the same thing and are having to replace the throttle body. Hum. Wonder if the manufacture of the part supplies to both Chevy and Ford. Good luck and if I can get them to replace part under warranty and that remedies it I will let you know.

Interesting - I have had 6 Explorers/Mountaineers since 94, and only the 94 and the 02 had the 4.0L engine. The 02 whistled, and they never really got it out. Which is why I went back to the 4.6L in the next two. Best way to avoid it, I figure.

Could be a bad catalytic converter, but you would probably have a check engine alarm. Try turning the key to the running position, engine off. Then get under the car and in the engine area and smell/look for leaks. Don't smoke while you do this. If you smell gas while driving, it's not from the catalytic converter, most likely kiawah is right, some leak around an injector or something like that.
#5703 of 6400 98 explorer spark plug issue?
Feb 12, 2007 (7:13 pm)
We have a 98 explorer 4x4(v6), for a while it was not idling it would die if you took your foot off the gas. We changed the spark plugs and it quit doing that, but it now sputters and misses and acts up horrible. It hasn't died yet, but it doesn't want to go and is really burning gas. Any advice would be appreciated.

Clean the mass airflow (MAF) sensor. May not be it but a good start.

Another thing you might want to try is cleaning or replacing the EGR valve. If gets stuck open it will cause the stalling at idle. My 99 XLT had the same stalling at idle problem and the EGR fix did the trick. I removed the EGR Valve and cleaned it with some WD 40. There is no guarantee this will work, but give it a shot if the other suggestions do not work.

Thanks for the response. Have verified that the problem is the blend door. Either the circuit, actuator or door. Guess it will have to go to the dealer. Not concerned as much about the money as I am about how much damage they will cause while doing the job.
