Ford - Bronco :: 1989 - Shudder And Power Loss For A Second Or Two About 500 RPMs
May 6, 2012
When my 1989 Bronco II has about a quarter tank of gas left, it begins to "shudder" and lose about 500 rpms while I've got my foot on the gas. It will shudder and lose power for a second or two, then run fine for a minute or so, then do the shuddering stuff again. It'll do this all the way to the gas station. But with the tank full (or even half full) the shuddering stuff is gone as I drive out the gas station.

Ok, I have a 95 F150 5.0. It's sat for 6 months with the engine taken apart. I just finished putting everything back together with a new alternator. Well, I pulled a bone-head move and forgot to connect the harness when I fired the truck up. Other than not charging though, it ran fine. When I connected the harness, it began to chirp and shudder at low RPMs and squeal and vibrate at higher RPMs and it over heated VERY QUICKLY.
So hot the case was too hot to touch and the pulley smoked the belt. The engine didn't even have time to get up to operating temperature. I've had the alternator replaced twice, and this last one tested good putting out 14.5 volts. The work I did on the engine was to replace the valve springs, install a direct drive timing gear, replace a spun harmonic balancer, bypass the smog pump because it froze up, new distributor, a new ECU and O2 sensor.

I purchased my 2013 F350 PSD July of 2014 and immediately noticed "the shudder" when the engine was lugged down to 1000-1100 rpms on a hill. Sounding like somewhere around the turbo belching air too. At first I was startled but learned to manually downshift to higher rpms and it will stop. Once or twice I tried accelerating out of it and it shuddered as bad as the poster who said it made the steering shudder too.
My truck has 16,000 miles and I never let the rpms drop now. So I figure I have a real problem I'm not imaging. What should I tell my dealer is the TSB or remedy ?

I have a 2012 F-250 6.7L w/8K miles. I have been struggling with this issue for 6 mo. The engine feels like its missing at low RPM. I would equate it to the feeling of a bad coil pack in a gas engine. The boost indicator drops to 0 for a split second then recovers. The dealer says they can't find the issue but went ahead and replaced the turbo. After the turbo replacement It got worse. This is an intermittent problem with no codes.

2002 ranger edge 3.0 5spd. Truck idles perfect, but when you get rolling and higer rpms feels like the engine is missing. loos of power and shakes. I replaced the usual, plugs and wire's, seemed to work for a bit but came back. I cannot get any info on the scanner and have checked all the fuses. I am thinking coil pack but don't understand why it idles perfect and only misses under acceleration. No check engine light on.

I seem to loose almost all power once I hit 5k rpms. Like I will floor the car and Ill feel a nice pull and all of a sudden once I hit 5k it slowly starts climing like a hybrid civic. wtf? Could this be a misfire, tune problem, exhaust leak IDK

The past couple days when driving to school in the morning i've been noticing that my car starts to rattle and struggles to accelerate once I pull out of my driveway. Once i get to the next stop sign to take off the car runs fine like nothing ever happened. My check engine light doesn't come on though. I usually let the car sit for about 30 seconds to a minute before i start to move the car. Mods I have are Unitronic stage 2, Forge 007p DV with yellow spring, and 3" downpipe.

My Legacy sedan is not behaving well. On more than one occasion, when pressing on the accelerator, the rpms do not rise. I put it in park and try to press gas pedal, nothing. Turn the car off and let rest for a few minutes, then start it up again, and it's fine.....

So over the last few months I have been having more and more idling and power loss issues with my 2006 V6. When idling she intermittently will try to stall and the rpms will drop below 500 and then spike back up. A large percentage of the time I hear a loud whining sound while driving down the road and I notice that turning off the air conditioner will remove the sound at times.
***what I have done so far**
Idler Pulley
Belt tensioner
sepentine belt
cleaned MAF
Cleaned Throttle body
Throttle Position Sensor
Had car reprogrammed
So I pulled the belt off and checked all the pulleys and did notice some grittiness in the AC pulley (inner) and was wondering if this might be the issue. Attached is a video I uploaded, Video .....

So my 2005 elantra 2.0 CVVT has 189k on it 1 owner.
I got a check engine light one day and i read the code. Came out to be 02 sensor code bank 1. So i order a denso o2 sensor and replace the part.
I drive the car for about 400 miles to reset monitors and get a check engine light. P0420 cat code. At this point the car drives with normal power and pickup.
1000 miles later my car has lost power. It doesn't have any get up or power when driving normally. I take the car to my local shop and they recommend replacing front cat. I replace front cat, same issue.
At this point i'm not sure if it is a transmission problem or maybe my 2nd cat or something else?
On the freeway if I put my pedal to the ground the rpms surge up very very slowly,
Also seems like the car doesn't shift till around 4k rpms, seems like previously it shifted sooner.

I have an 05 corolla XRS. I just had a sport clutch put in about 1 year ago. Whenever I shift into 4th gear and accelerate, the RPMs drop about 500 and I lose power for about 3 seconds before it starts going back up. Other gears are acting normal. Best part is that I let my friend drive the car earlier and since he did it's been doing this.

I got an old 1989 F-150, manual, in-line 6 engine, with an 8-foot bed. I use it for hauling landscaping equipment, as i am starting a business. i will likely start hauling trailers with it this summer, but I also just want the engine to give me more power.
What are some things I could do to up the HP, or a better truck in general. I'm not looking to make it into a 350Hp monster, just get a little more out of it. What can I replace or add that would do this?
First, the idle dies on me when i put it in neutral, or gets stuck at 2500rpms. is this a vacuum leak, or the idle-air control valve?

Truck sat for 1 1/2 years. Changed filter and put in 15 gallons of fuel. Had maybe 1/2 gallon old fuel in tank. MAYBE. Fixed fuel line because it wasnt getting fuel and it fired right up and idles great.
Truck has no acceleration over 2500 (or so) RPMs but idles fine. This is depending on how hard you push the pedal of course.
If you drive the truck normally like a grandmother it seems to be ok. As long as you dont need a passing gear or need to accelerate more than 1/4 pedal
If you try to push the pedal to get the next higher gear it will sometimes hit the gear fine. IF you floor the truck it will totally lose acceleration. Then the truck will run like crap even slow for a good while. But then it will clear up for the low end. Then you can drive it normally. Then when I think I can test the upper end I get the same thing again.

I have a 1998 Accord, 4-cylinder VTEC standard transmission, 226,000 miles. Last fall I first experienced a problem with the car where within 5-10 minutes of starting the engine and driving, the engine seems to lose power/fuel and RPMs act as if they'll drop low enough for the engine to stall. If I take my foot off the accelerator, and reapply, the engine seems to gain power again.
Also, if I open the accelerator to full while the problem is occurring, it can occasionally "push through" and gain power again. Similar things will happen while stopped. In neutral, RPMs fall low and suddenly jump back up and then settle into normal idle. The problem never persists longer than 10 minutes within starting the car.
I took my car into a local shop that came recommended by a friend. They investigated a "check engine" light that didn't explain the problem and were never able to recreate the condition themselves. They replaced a few parts but lost the work order so I don't even know what they changed, but the problem seemed to have solved itself for a while. Recently it started up again and I would love to sort it out.

I have a 2005 Honda Odyssey with about 190k miles on it. About a year ago (175k), we had our Transmission replaced with a re-manufactured transmission from the Honda Dealer. Now almost a year later, we were driving home on the freeway (about 4 hrs of highway driving) when we smelled and saw smoke coming from our hood. No lights or indicators came on. We also started losing power and the RPMs were high.
We pulled over in a gas station and popped the hood. A guy who said he was a mechanic took a look and thought it was the radiator host leak...suggested we add water and limp the rest of the way home. We did this and had no issues for the remaining 40 minutes of driving. The next day we brought it to our normal mechanic (not a Honda dealer) and he said it was transmission fluid ...thought that the transmission fluid that was splattered all over our engine/hood/wheels.
When we took it to the honda dealer (since we were still under warranty for the Honda transmission), they looked at it, cleaned it up and ran tests. They are saying that other than being low 2 qts of Trans fluid, they don't see any leaks/problems with the transmission, even after test driving it. They are wondering if the transmission cap was not tight or left off, causing the fluid to overheat, etc (I'm sure it wasn't left off as we have been driving it for months since our last check up without issue).
They say they can't replace it under warranty unless they can confirm some issue in their diagnostic tests. How can we have 2 qts of transm fluid splatter all over our engine and there not be a problem they can diagnose? Did they not give it enough time (e.g 4 hr long distance drive) to heat up enough to replicate the problem? The question now is...is it safe to keep driving the van (after doing a transm flush) or are we just asking for trouble until the next episode? How can I convince the dealer that there is a problem and have the transmission replaced under warranty?

1989 Saturn 5 speed, 4 cyl, 185,000 miles. Just started overrevving, when I try to go into 1st or 2nd or idle RPMS jump to 4500. So not a good thing. Do not tell me to buy a new car, not in the budget, or maybe it is.

I was sitting in my car waiting for someone, and noticed that whenever I pull the window button(s) to pull a window up (esp if the window is already up), the RPMs dip and a shudder is felt through the car. What's up with that!? I tried it about a zillion times: pull, dip, shudder.

I drive a 2008 Elantra automatic,and have a constant engine shudder/vibration whenever the rpms are between 1000 and1500. The engine shudder stops as soon as I accelerate above 1500 rpms,or take my foot off the gas completely.
The dealer recommended cleaning of the fuel injector system,not sure if thats the course to take.I do know my model has had fuel pump issues,but the dealer has told me all recalls on the car have been processed.

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??
