idle

I have been trying to track down a noticable winding sound at idle. The sound gets louder as rpms increase until the engine drowns it out while driving. I have already replaced the tensioner, and idler pulley up top. The vehicle has 160,000 miles so I shot off the parts cannon thinking those...

Hi there! Everything was great. Then this happened: Drove to work for the 50th time this month. Finished work. Hopped in the truck after a long day. Started it up just fine. noticeably rough idle, huh, that's new! popped it into reverse to back out of my spot, definitely bumpy and rough, had...

Help! My sister has a ‘96 Explorer that originally wouldn’t start, when we did get it to start the idle was very rough. Changed the air filter, cleaned the throttle body, replaced the fuel filter. The idle got better, but now when accelerating if you’re giving the truck gas and immediately let...

Hello all, Explorer is at 82000 miles and have had no accidents. I am currently in a pickle. I am having an issue with my explorer stalling in dangerous spots. I will be driving in the morning, and typically in intermittent stop and go traffic, after about 25 min of driving, my car will start...

My '99 Explorer EB 4.0 has an intermittent staring problem. It starts up fine, but when coming back down to idle RPM, it sometimes drops significantly and then dies. Doesn't happen all the time. I've been giving it a little gas each time after starting which has solved this problem, but would...

Hi All, I don't notice a RPM issue in the (cool) mornings, but warm-up engine gains 500 in the heat of the day. Hmm? Ideas welcome! Best! .cd 1994 4x4 auto XLT 4.0L

Hey, I'll start off by saying, I'm Austin, I own a 1998 Ford Explorer aka Exploder! It has 223,0000 on it and it's the OVH 4.0 v6! Now my first problem is a rough idle that has killed the engine three times (yesterday) When I was driving it, it ran fine, and then when I got to my fire...

Hi, I have a 2005 eddie v8 4x4 Some days my idle is normal and once in a while (maybe at least once a week or more) my idle falls to 600,580,500 rpm range or it bobs from 640 to 580rpm(estimate) in gear only if i put it in park it goes back to normal. It used to also idle a little high along...

Hey All, So I've got a 1998 Explorer Sport 5 speed manual 106k miles. It's got an X in the vin so I believe it's the OHV v6. I purchased it at 104k and its ran fine since then. Recently it has started stalling out on start. It'll rev high and then drop to a stall. If I wait a few seconds and...

Since getting my scan tool, I’ve noticed that my rpm’s decrease and increase slightly in park, and in drive with the brake on. Does this happen to anyone else? It’s not a huge change, but they do move up and down by about 10 rpms every second. This was over the course of a minute:

I was replacing the fan clutch on my Explorer and decided to go ahead and replace the serpentine belt. After I got everything out, I realized that the idler pulley, which is on my serpentine belt diagram under the hood, is non-existent. I'm not immediately worried, since I've been driving around...

I have a 1995 Ford Explorer OHV V6 XLT. At idle it vibrates a lot and at acceleration it seems to sputter. All air lines seem to be tight. I just put a new throttle position sensor in and all my spark plugs are moderately new. I did just order new wires which I will try soon, I don’t usually...

Hi Everyone. I’ve got a 1993 Explorer XLT that has developed a strange noise under the hood and a rough idle. In the last week I’ve noticed that it seems harder to start, and idle seems to be quite rough. A couple of times it has died while idling. As of today it is stumbling so much at idle...

Hey guys, I have a 1993 Explorer XLT with 120,000 miles bone stock. Since I purchased it in March I have noticed that when the engine gets very warm like around or above the M in normal, (from idling with the AC on to cruising the highway in 100 degree weather) when I shut the car off and...

At idle, or when under about 700 rpm, my explorer makes a weird ticking/chattering noise. It sounds like it's coming from the front of the engine so I replaced the idler pulley and tensioner which made no difference. So I was trying to figure out what the noise was and it sounds like it maybe...

Hey guys! My Explorer when at idle it fluctuates from about 700-950 rpm. I tried to clean the IAC and it didnt seem to make a difference, if anything it made it a little more noticeable. It only has 110,000 miles on it and has been regularly maintained its whole life and taken very good care of...

2003 Ford Explorer Eddie Bauer Edition 4.6L V8 4x4. The stalling issue is most common at stop signs, when the vehicle is in drive and idling at operating temperature. It has occurred in park while cold, however. I immediately thought IACV since Fords have that issue, and it was shuddering a...

So the truck started shaking about a month ago, idk where this came from, the car did start feeling funny as i accelerated, but that went away to my knowledge after i changed the oil, I have no warning lights or anything, I changed the oil, im thinking maybe its tune up time? Any help would be...

Hi guys, I've got a 98 SOHC 4WD XLT. I was driving along and noticed that when I took my foot off the gas the XLT was idling high enough that I had to brake to keep it under the 25 MPH limit. When I got it home and put it in park the idle went up to 3000 RPM. I expected major vacuum leak. so...

Hey Guys... So I do not know much about cars BUT I have been learning. This car is literally older than I am.. So I am trying my best to get this car running to its optimum efficiency. So CURRENT on going problem. STARTING the car is a bit*h. It takes me at least 2-4 turns to get this car to...

Does anyone know what the part number is for the motorcraft IAC? I see CX1914, but then there's different numbers as well. Such as YU3E9F715BA and YU3Z9F715BA. This is somewhat confusing.

I plan on modifying and installing a Sanders a/c compressor to provide unlimited air, to maximize effectiveness and efficiency, I've been trying to find a way to install/fabricate a high idle switch to use when the compressor is being used. It'll hold the engine around 1500 rpm ideally. Does...

Yesterday afternoon I went to start my 2003 Ford Explorer Sport (4.0 SOHC, Automatic, 2WD, 160,000 miles) and it popped; smoke came from under the hood. I assumed it was electrical; however, there are no noticeable charred wires or melted components. Upon opening the hood, there was some...
