Ford - Bronco :: 1996 - High Idle While Coasting
Apr 10, 2013
I bought a 96 Bronco 5 speed manual last year in pretty good shape.Everything works well, but the idle speed at coasting is hovering around 1500rpm until the vehicle slow down to 30mph at which point the rpm drop to about 700 (where it should be).It only happens while coasting.When truck is parked, the idle is fine and steady; I revved it up to 3000rpm for a while to see if I could replicate the behavior, but no, as soon as I release the accelerator, the rpm's drop nicely to 700.While driving though, if I switch to neutral, the rpm will go up for a second, and than sloooowly drop to around 1500 and stay there until I slow down to 30mph. Spark plugs, distributor cap and rotor, wires, TPS, ICM, and MAF are new. Could it be ECM?

I've had a vibration since I bought this Bronco 7 yrs ago. I have replaced everything underneath from front to rear. Tie rods, ball joints, wheel bearings, U joints, shackles, etc. As I replaced things, the vibration got better. Or at least wasn't as violent. Now, the vibration is becoming LOUDER. It only happens during acceleration. I can get up to 65-70, let off the gas, and all I hear is the beautiful sound of the tires. If I get back in the throttle, the sound of the rumbling vibration drowns out the stereo. Also, I have recently noticed a squeaking sound in the rear, under acceleration.

1996 Ranger 2.3 140 CID XLT 126,000 Miles. When coming to a stoplight or stopping the engine idle is low and causing engine to almost die. Engine has been stuck at high idle a couple of times. It started with the engine idle slowly coming down and now it its too low. I suspect the Idle air control valve.

My 1993 5.0 liter bronco is making a strange ticking noise. when it's idling, and it ticks, the idle drops. then it will tick again and the idle will raise up. usually between the 600 to 1000 rpm range. it just started doing this and never did before.

Have a 93 Bronco, 5.0. replaced battery, IAV and had a complete tune-up. Now starts great, runs fine until it gets warm, than in about 5 - 10 minutes the idle starts to fluctuate. A little at first but eventually between 1000 to 300 rpm and will stall if you don't give it some gas. Turn it off, restart, starts fine and runs OK again for a while.

but 2nd time 6.0 psd owner. 2 weeks ago we picked up an '03 Excursion and were thrilled because it's been running like a dream and getting great mileage. However, according to my wife just yesterday, and after me driving it today, we have a big problem.
The engine starts, momentarily runs smooth, but then quickly becomes very rough. When trying to drive, it will make decent power, but it has an "off" feel to it, like it doesn't quite make as much power as it did, and it has a slight vibration to it.
Then when you coast to come to a stop, or pull in our driveway, it runs REALLY rough and badly, and usually stalls. I have begun the troubleshooting process. Here's what I know: Ficm tests good - 7 pin w/key on only gives ~46V (only tested w/voltmeter) Had an oil change done today and added a bottle of Hot Shot, will add the fuel treatment when we put more diesel in Believe ICP sensor to be OK. I unplugged it and no change Appears all injectors are firing since it ran down the highway decently, AND you can hear all injectors 'triggering' in a uniform manner with key on Turbo probably isn't sticking because made great power before, and decent power even with the problem NO Check engine lights / codes thrown
Details about the truck:Early '03 w/ 189,000 miles EGR delete done in a previous life w/ IPD kit Turbocharger replaced, in a previous life Headgaskets done, in a previous life (no ARPs though )
Questions & next steps:Even if there was no change w/ ICP unplugged, does that truly rule the ICP out completely? Could the IPR be the culprit?
Others? I have ordered a Scangage 2 and it will be here Tuesday. What's the first thing I should check? To me, this very much seems like an electrical problem; my gut tells me it's some kind of sensor or electrical signal error. What's the best way to investigate this path?
The engine turns over very well, and sounds very uniform so I don't think compression is the issue. Head gaskets have been done, although not with ARP studs. Batteries are very fresh and turn it over very fast. I have already learned a ton reading through these forums and just need some additional direction & brainstorming!

I'm stuck in a bad situation. With my work schedule it will be literally a month until I have time to look at my car during daylight. I may be able to drop it off next week.
Anyhow, the R is making a horrendous high pitched noise while coasting to a stop. This starts at just under 30 mph and is most pronounced in neutral. Accelerating in gear stops it. It is loud inside and louder outside and there is some rough "clanking" associated with it. My guess is a belt or bearing. It is coming from the front passenger side.

Noticed the barely audible (with good ears) high-pitched sound that emanates from the car when you let off the throttle enough to prevent any charge or discharge bar from showing? It goes away if you completely release the throttle or if you press the throttle a tad bit more.

I finally got a recording of this, after trying to describe it without much success. Dealer drove the car 2x and claimed they don't hear it.
Video here, turn up your sound... noise happens just as the gas is let off...
As you can hear (if you turn speakers up, recording isn't very sensitive), it's kind of a high pitched whistling sound or whining sound. Happens when coasting (foot off gas) at 60mph. In gear or neutral, same noise. Only around that speed, only when foot off the gas.
What do you think this is? Some have suggested wheel bearing but if you listen this is more of a steady high pitched noise, not a helicopter like sound.

I've got a 2004 Mazda 6 with the 3.0L V6 & a 5-speed, with about 128k miles.
The car runs fine, but was leaking oil onto the exhaust manifold and so I recently had the valve cover gaskets replaced. the mechanic could not get replacement gaskets from Mazda, and so changed the valve covers themselves also, and consequently needed to replace a couple of hoses that connect to the valve covers.
Since the repair, the car drives fine - acceleration seems normal, I don't notice any performance issues. The CEL is NOT lit.
1) When the car is in neutral, but rolling, the idle consistently bounces back and forth precisely between 1250 & 1500 rpm. This occurs always, and happens whether the gearshift is in neutral or the clutch is depressed. With the radio off I can hear the engine surging when this is going on. As soon as the car comes to a complete stop, the idle immediately drops to the a rock-steady position just below 1000 rpm, as it always has.
2) I assume related to the above, but since the repair my gas mileage has dropped from its usual 18-19mpg to 15.7-15.9mpg as recorded at two fill-ups, and my current tankful is looking to return equally low mileage.
I brought the car back to the shop and the mechanic took the car out for a drive with me, with his computer hooked up while we drove. He found nothing wrong, nothing out of whack, and saw no evidence of any air leaks.
1) Seems strange to me that the valve cover gasket couldn't be obtained, and new valve covers were needed. I want to believe the garage is being straight with me. Is this really plausible?
2) What could cause the idle to behave this way? I understand what a valve cover does (in my earlier years I changed the cylinder head on my old Saturn) and can't figure out how or why changing the valve covers would have an effect like this.
That leads me to conclude this is more likely caused by the new, slightly different hoses attached to the valve cover, but I don't know exactly what those hoses do or why they connect to the valve covers, so I'm stuck here.

My 1996 Taurus has 202,000 miles on it. One day a while back I was headed home from work. I had the AC on and fan on HIGH. I all of a sudden started smelling something hot. I threw my sunglasses into the passenger seat and saw a gray haze in my interior and slammed on the brakes and pulled over thinking my car was on fire. I got out quickly and looked under the car and then under the hood. I then followed the HOT ELECTRICAL smell to passenger side floorboard under dash. Blower motor part so I changed it. The weather got cool again so i didn't need AC for a couple of weeks. Now, ANYTIME I try to put the fan on HIGH I get that hot electrical smell. The fan has 4 settings, on the first three it's fine, but as soon as you put it on high it smells very hot. My AC isn't as cold as it used to be but it was like that before the fan motor gave trouble. I think I just need to charge the system. Why my fan motor gets/smells hot on high setting. No fuses has blown. I definitely don't want to burn this motor up. I got new fan motor that has the same electrical connection so I didn't have to splice anything. Is something overloading??

Here is my issue, none of my fan speeds work except for high. It doesn't matter if it is on heat or a/c. I know on other cars there is a resistor that needs to be replaced and then I've also heard of blower motors going bad. I switched out the switch to see if it was that, and it wasn't. Is there a common problem out there and where is it located?

I have been getting a code 18 which is a loss of tach signal. I have checked the distributor and the module and they are both good. Where do I start next?

I have a 1988 FORD BRONCO, full size, that has a peculiar problem. I tried starting the car and it turned over, but when I tried shutting it off it kept turning over. I had to disconnect the battery to stop it. I replaced the solenoid being careful to route the wiring connections the same way. I tried starting it and it shut off using the key switch the first time, but when I tried starting it again it wouldn't shut off so I had to disconnect the battery. What might be the problem? The ignition switch??

So three weeks ago, yes 3 weeks, my loathed Bronco decided not to start. It has been sitting at my office parking lot since then. Every day at lunch and after work I spend some quality time with it, attempting to coax it back to life. Here is what I've done so far...Installed a new ignition coil (gets 12+ volts with key in 'run,' and ±10.5 v. when cranking), a new distributor, (with PIP) cap & rotor, new remote mounted ignition control module. All voltages and resistances throughout the ignition system are good according to the Hayes repair manual but there is no spark being sent to the distributor. I've also done an ECC self test and got no response at all. Does this mean the ECC/PCM is bad? My butt is in so much pain with me having to ride a bicycle everywhere. (Riding in the rain while carrying an umbrella is no fun!).If I don't figure this out soon I suppose I'll give the Vehicle Donation Program a call.

My son just purchased a 1996 Ford Ranger 2.3l 5 speed it is a nice little truck. But I have a question when you press in the clutch it acts like the choke has come on it idles way to high. When you come to a complete stop it is a few minutes before it goes back to its regular idle. Is it suppose to do that?

When I go out to do errands around town (I live right in town) I get horrendous gas mileage. Now, I understand gas mileage is high at the beginning of a trip, but for this long and this high and under these circumstances? I'm getting ABOVE 10l/100km when I have 80% charge available (for americans, that's disgustingly high MPG like, pick-up truck high), AND my foot is completely off the gas. Literally, coasting, or braking, and I'm still sucking up gas. What the heck?
Is this just because it takes a certain amount of time for the engine to run no matter what or something? I still don't see any reason for me to be eating up all that gas when my foot isn't even on the gas AND most importantly, I have charge available. Feels pointless for me to use my car for what I use it for 70% of the time, which is for quick errands around town at low speeds. Thought the prius was suppose to be a superstar for this kind of thing.

The drive selector on my 2000 Ford Explorer Automatic 4.0L will not allow selection of low gear. The selections are shifted to the right so the last one, low gear will not select. When in park, P, it shows R. When in drive, D, it shows as 2 and when in 2 it shows as 1. Then it will not allow to shift in to 1.The settings are off by 1 knotch. what's up with that? It runs fine but cant get to low.

I have a 1988 full size Ford Bronco that when I start it the motor keeps turning over even when I turn the key off. I installed a new solenoid thinking that would do the trick and it worked correctly the first time, but the second time it kept turning over until I unhooked the battery. What is the problem? Is it the ignition key?

The panel goes off and the fan quits blowing. Sometimes it works, cools great, then just cuts off...
1989 Bronco II 2.9 4x4 auto 164k miles... I have been on TRS, BroncoII Corral, and even FSB searching.
This is the first attempt at reaching out because i have found that here at FTE the folks that chime in know their stuff, or know where i can find out for myself.

I was thinking the other day, wonder if a 66-77 bronco 9" axle would work, width wise, on an Aero? Obviously, you'd have to grind off all the mounting brackets and add the Aero ones. Mostly just building the "ultimate Aero" in my mind,
