#2046 of 6400 That *rotten egg* smell.......
Aug 25, 2003 (4:36 pm)
Purchased a 1997 Explorer Limited, V8, AWD, with 41k on it about 6 weeks ago. I've put 5k on it in the time I've had it and whenever I got up a hill or get after it in any way, especially if it has to go about 3k rpms I get that lovely sulfur smell. No engine lights on or anything, truck seems to run really good. Was a city driven truck, I know that, one owner, a woman.
I drive on the highway 75% of the time, so I'm sure its a change for the truck. Any ideas? The Ford dealer wants $83 to *look* at it.

Try a different brand of gas for a couple/three tanks and see if that helps.
The sulfur smell seems to be a problem with lots of different cars these days, esp. the 4Runner and MPV that I know of off-hand.

Don't worry, I'm not considering the JGC just because of some transmission failure posts I've seen here. Drive the the Explorer and the JGC and unless you plan to do some serious off roading, the choice becomes clear. While I don't expect a Cadillac ride or BMW handling in an SUV, I was very impressed with both Explorers I drove(new 03 models). Since I'm likely going to be going the used route, I'm just looking for potential or "perpetual" problems that I should look for when test driving and inspecting the vehicle.
demographics, while older poeple may be less inclined to use the internet than younger folks, they are VERY vocal in other ways if they are dissastisfied with a product. I sold home theatre components while in college and when an older couple came in, you sold them the better products not simply because they would buy it, but because you WANTED them to be satisfied. Otherwise, you heard about it from then on.
#2049 of 6400 rotten eggs
Aug 25, 2003 (9:31 pm)
I agree with Steve. Trying a different brand of gas is the easiest first step. The rotten egg smell is the failure of the catalytic converter(s) to process enough of the sulfur from combustion. But the catalytic converters may not be the root problem. High-sulfur gas or just a rich running condition could be the problems. A little egg stink is normal during cold warmup. If it continues after a gas change, start keeping track of your fuel economy.

I tell you one think strange I've noticed on the new Explorers is the tendency of the back glass to be misaligned. I've seen a ton of them just riding behind them around town (I stalk cars?). They all seem to start out right at the top, then by the time the window/sheetmetal gets down to the taillights something is way off. The clearances are way off from one side to the next. Maybe something to look at...

It happens no matter what kind of gas I put in it, I've tried Chevron, Tesoro, Texaco, doesn't matter at all. Tonight it was really bad and also had a nasty burning smell to it. When I filled it up tonight I added some fuel system cleaner (Amsoil P.I.), didn't smell anything on the way home, but I'm not convinced that will solve it.
Its fuel economy is excellent, on the highway I average 19 to 21 mpg and around town I get 16 to 17 mpg. Can't complain about that from a V8 AWD.
There are things about this Explorer that are VERY frustrating, the egg smell, the leaking front doors (ever get wetter inside the truck than outside during a rainstorm??), and it has a nasty exhaust leak in the engine compartment, of course I don't think that has anything to do with the smell since its only noticeable during acceleration up until about 40 mph and I never smell anything then.
Oh well, its almost paid for, so I'll stick it out for a while.
If anyone has any other ideas throw them at me, if I haven't tried them I'll certainly toss them at the Explorer......*grumbling* Cantankerous little beast.

Your idle problem is a bad IAC (idle air control) valve. My '02 did the same thing. It was under warranty so the dealer ordered new. I spoke to the tech and he said he could clean it, though. If you're out of warranty it might be worth a try.
I had the exact symptoms you described. It would start and die immediately. I could keep it running by giving it some gas to stay out of the idle circuit, and after it warmed a little it was fine.
After the IAC was replaced it's been fine.
#2053 of 6400 98 ford Misfire
Aug 26, 2003 (7:51 am)
When starting cold or after sitting for about 5 to 10 min. the engine will run smooth then start to misfire. I am beginning a slight sluggish at moderate acceleration. I also checked the throttle
body and found carbon build up (acording to my haynes manual the throttle body is coated with something to prevent this and not use any chemical to remove this build up) also the manuel something
mention about the fuel filter being for the life of the car and maybe
water in the fuel line...........washijlauburn.edu
#2054 of 6400 fuel filter nonsense
Aug 26, 2003 (9:07 am)
I don't throw my cars away when the fuel filter is becoming restricted, and neither should you.
30,000 between changes on the present generation of in-line high-pressure fuel filters. unless you are running slop sucked off the pavement at gas spills, that is plenty of mileage... there should be some dust and lacquer in the filter by then, but pressure restriction should be minimal.

If your throttle body has a carbon build-up, your MAF sensor may also be dirty. There are small wire elements on the MAF sensor that sit in the path of the air flow that can collect gunk on them.
If I remember right, there are 2 star screws to remove on the sensor. After pulling the sensor out, clean the elements with throttle body cleaner and re-install. It's an almost free fix thats worth trying before dumping money into it.
