My 2008 Ford Focus SE hesitates at highway speeds, seems to decelerate and accelerate, sometimes more, sometime less and sometime not at all. dosn't seem to affect the acceleration.
View 1 RepliesI just got my new 2013 Persona Prius on Saturday. I haven't put too many miles on it (under 200) but I'm noticed that a feel a stuttering or hesitation when I reach highway speeds. Typically about 65 -70mph. I can't think of a better way to describe this but it feels like the when driving a manual transmission, when you need to shift to the high gear? That kind of stuttering feeling. I'm sure that it's not the same problem but it feels like that. Once I go faster, the feeling stops. Or slower. But going between 65 to 70, it's the same feeling.
View 2 RepliesPurchased this car new. 2008 GLS w/ V6 2.7L engine. Wife's car, so I rarely drive it. She's complained for a month about an intermittent issue with the jar "jerking", usually during slow speeds.
I felt it for the first time myself. Was halfway through a pretty tight curve at around 20 MPH, starting to slowly accelerate when I felt a definitive lurch. might have been momentary loss of acceleration, or transmission. Not sure which. No CEL thrown.
I did see another thread mentioning a 2007 with a similar issue, but that person had codes thrown that pointed to a Throttle position sensor and a need to reflash a transmission. Think I'm seeing the same situation, or would this be different ? Absent any CEL, I'm sure the dealer will not be able to find it....
06' 5.4 screw 100K... At 55mph my truck just stopped running, I pulled over to the side of the road and after two trys the truck restarted but ran rough. Auto Zone pulled a code that said replace the throttle position sensor, I did and the same thing happened again two weeks later just as before.
View 3 RepliesI have a 2007 F150 King Ranch Super Crew 5.4 3v and it makes a ticking sound. I have read about the VCT solenoids and the phasers. My issue is that the ticking noise can be heard at Highway speeds. At it seems to be quicker as the engine speed increase. Not sure what to think. No rough idle. What could this be.
View 3 RepliesFirst, details about my truck. 2007 F150 SuperCrew, 2wd, 5.4, 203,xxx miles on it, leveled with Hell Bent Steel 2.5" kit last year, has been aligned professionally since then, tires are good and balanced.
The issue I have is a vibration, kind of the same feeling when driving on a road surface that has had the top level of asphalt removed before it's resurfaced. It's mostly noticable at highway speeds. Its not a violent type vibration, but you can feel it. There is also a sound, similar to tires with a deep off road type tread.
The sound and vibration more noticeable when making lane changes or when wheel turned towards left, at highway speeds, not as much to the right. I've checked front wheel bearings, they are good, zero play, no loose suspension parts, u-joints are good, no leaks anywhere.
Since it makes the noise and vibration a bit more when moving wheel, could it be a power steering pump? The pump is the original.
5.4L... My truck has a momentary moan / growl / bog down issue. It happens at town and highway speeds and usually when I have cruise on OR when I lightly apply the gas peddle. It moans for a few seconds and seems to bog down then comes out of it and carry's on its way. You can hear it plainly while driving even with radio on. I have a regular muffler on the truck but when this happens, it makes it sound like I have a catback on it.
Things i have done...
- New air filter
- New oil/filter
- New fuel filter
- Ran techron injector cleaner through tank of gas
I have an '05 F150 5.4L with 110k miles on it. Bought it used about 2-3 years ago and have had on-going ignition system problems. The current problem is a significant shudder/shake/vibration that occurs when driving 50mph+ (easy to reproduce around 65-70) on the freeway, when starting up a minor, but noticeable incline. This is an incline that doesn't require much additional throttle, and this trouble occurs with cruise control on and off. the truck starts shuddering pretty rough during the incline. However, if I release the accelerator (and go up incline with slightly lower speed) or give lots of gas on accelerator the shudder usually stops. The shudder always clears after the incline when returning to flat road and just cruising.
This occurred on a recent trip a few times and I pulled the following codes (in order):
P0356 (once) : Ignition Coil F (6) Primary/Secondary Circuit Malfunction
P0302 (recurring): misfire on cylinder 2
I have since purchased and replaced the coil on #2. This did not resolve the problem. I have replaced coil on #6 in the last year...
Because I saw a suggestion somewhere on the net around this problem while searching, that this could be related to OD, I tried disabling OD and enabled OD on an incline today to test after replacing COP on #2 and it seemed to resolve the issue to turn OD off. Not sure if related...?
Other observation: Cab of truck often smells of gas just after starting the truck. Mentioned this to the shop, but they didn't find anything obvious.
Short history of codes and work that has been done:
Sometime in early 2011: Ford service dept did this work.
First failure was coil bad on #7. Tech swapped 7 & 8 to verify the problem followed the coil. Then when the problem DID follow the coil, he replaced #8 with new.
05/2011 MacKenzie Ford changed all plugs
12/2011 - swapped out COP on #7.
02/2012 - P0306 - Now, COP #6 is reported as bad.
November/December 2012
P2104 P Throttle Actuator Control (TAC) - Forced Idle
P2112 P TAC Stuck Close
P2111 TAC Stuck Open
I did throttle body clean - removed it and used TB cleaner. replaced...
Late December 2012 - while driving on freeway at speeds 50+, but easily reproduced around 60 after starting up a slight incline. symptom is heavy shudder/shake. Possibly resolved by turning OD off.
P0356 (once) : Ignition Coil F (6) Primary/Secondary Circuit Malfunction
P0302 (recurring) : Misfire on cylinder 2
2006' screw, 5.4L, 116K miles ... The truck looses power at highway speeds to the point that I need to pull off of the road. When this happens the check engine light is on and the truck is still running but will not accelerate, is it possible the computer is going into limp mode and if so what would cause this?
View 1 RepliesI've switched the fuel pump on this car more than once and made sure the fuel line isn't crimped yet it still hesitates. Also, the temp. shoots up when idling and appears to need either a fan or temp. switch?
View 4 RepliesSo my 07 with 125k miles has had new rotors for about 50k miles or so, but for a while now when the brakes get hot it gets a violent shudder on braking at highway speeds....the odd part to me is nothing at lower speeds, and not always at higher speeds....do I just have warped rotors again? The rest of the front end I good and tight....
View 9 RepliesFord Focus 2004 manual 150K miles. Most days the car runs fine. Other days it will start and run until it warms up, then stumbles or hesitates at speed. When this happens the headlights and dash lights are also flickering. Sometimes i hear a clicking sound behind dash, left side. I have the sure cure: turn the heater fan to high. This works every time. When the engine is hesitating, i turn the fan to 4-high, the engine smooths out. Turn the fan down, engine again hesitates. Hesitates at 3, worse at 2, worst at 1. It seems to need the extra load.
But after few minutes of high heater fan, the alternator light comes on. I flick the heater switch down, endure the hesitation for a few seconds, the alternator light goes out, engine still hesitating, flick the fan to high, engine smooths out. A few months ago i could get it to fun smoothly with the fan on 3, didn't need 4-high. Now seems to need 4.On the days when it is always running smoothly, the heater fan can be on any speed, the alternator light does not come on.
Next few days or even weeks the engine will run smoothly, no hesitation, with the fan on or off or any setting.
The car has been to three shops in past year, one of them a major Ford dealer, who kept it two weeks. The problem has been diagnosed as battery (replaced), Battery connections (checked), plugs (replaced), fuel pump controller (replaced), fuel pump (replaced - ouch!), alternator (replaced twice - ouch twice), grounds (checked). Every time they "fix" something the car runs ok for a week or so.OBD shows P2004 (intake manifold runner stuck) but all agree it can't be the problem.
There have been a few times when i flicked the heater fan to high that all the dash lights died, fan went off, headlights off, turn signals didnt' work, but the engine ran smoothly. Not so good on the highway at night!There have been a few time, not recently, when the car wouldn't start. No dome lights, no dash lights with key turned to ON, no clicking or starter with key turned to START. It acted as if my battery was missing. The cure was to turn the headlights on. All normal after that.
I'm having an issue with my wife's 2008 Camry. We're feeling vibration at highway speeds. Feels like it's coming from the front passenger side. We've had all 4 tires replaced (two of them replaced twice because we got lucky and the shop gave us a set of 4 for free with all the trouble we were having with the goodyear tires they sold us), and added hub-centric rings to her wheels. There are no noises to tell me whether it's a cv axle or a bearing. I've been under the car and the only thing I can find that comes close to loose is that the passenger side axle has a just a little more side to side play (runout - inner cv) than the driver's side.
View 11 RepliesMy wife and I have owned our '08 Corolla since brand new. It is up to 162,000 miles now, and has developed a fairly serious handling issue. The car wanders at highway speeds (60mph+). This generally only occurs with some wind, on a long straight without wind you can take your hands off the wheel and it goes straight without issues. With wind, either natural or from nearby vehicles, it wanders around even if you're in a long sweeping turn. It doesn't weave totally out of a lane, but it does feel very unstable. On dry roads it's mostly a nuisance, requiring two hands and being tiring. If it's raining, however, the car feels like it's trying to hydroplane constantly, although I don't think it's actually hydroplaning that's just the sensation.
It started probably 20,000 miles ago and has gotten dramatically worse in the last ~5,000. I took it to a shop and asked them to go through the suspension and they gave it a clean bill of health. After that I took it in for tires and an alignment (needed tires anyway) and told the tire shop what I was experiencing. They put 4 new tires on, plus an alignment, and said they didn't find anything wrong with it either. As an aside it's running the stock steel wheels still.
I drive 50 miles each way to work, mostly highway, so this is getting to be a serious problem. It's to the point that I drive my truck when it's going to be raining, and white-knuckle it in the corolla when it's dry out. I've read similar accounts, and checked everything that other people have found to cause similar issues, and so have two shops. Tierod ends and control arm bushings are good. The rack seems good (no play at all in the steering wheel) plus I've driven plenty of vehicles with slop in the steering and they didn't feel like this and only tended to wander when going straight because a sweeping turn takes the play out of the steering. The struts are original all around, but the car easily passes the "bounce test". Is there a better way to check them?
My T&C strikes again... Now it shakes when braking at highway speeds (thinking rotors are warped and need changed), but today the brake light, traction control, and ABS lights all come on and stay on when I drive...
View 4 RepliesHave a 2008 Elantra GLS with 63K miles. A/T was serviced by dealer at 51K. Car now occasionally downshifts from 4th to 3rd when driving between 60 and 70 mph. Happens only when trans is hot (after 2-3 hours on hiway). When it occurs, it searches for the right gear, going back and forth from 3rd to 4th for several minutes before returning to normal. One thing odd is if I shut the car off for 5 minutes after it occurs, it runs fine afterwards. Do I need an ECU update or do I have a A/T problem?
View 11 RepliesMy 2003 2.0 Zetec focus wagon has a problem when I hit the gas from a dead stop. The car hesitates for a second or 2, like it's not getting enough fuel, then it revs up OK. Not all the time though, about 1 in every 5 stops. Once it's moving, there's no problem, you can accelerate just fine. I replaced the fuel filter and added fuel treatment. I also saw it had a real bad valve cover leak that had flooded all the spark plug wells. I replaced the gasket, plugs and wires, but it didn't seem to make a difference. Using a scanner, I monitored fuel pressure at idle, it was about 38.5 PSI. When I hit the gas it it went up to about 40 PSI. I think maybe the ignition module/coil might be going out, but don't want to replace it unless I have to.
View 2 RepliesI drive a 2008 Dodge Ram 1500. It has 2wd, 4hi, and 4lo. I have heard from some old timers that if I drive in 4hi at highway speeds it will damage the vehicle. The manual does not say anything about not driving highway speeds in 4hi. I only drive in 4 hi when there is lots of snow on the road (I-25/I-70 between Colorado Springs and the mountains mostly). Any good info on this? I understand how 4hi is no good on dry pavement (I've made that mistake a few times), but in a snowy situation on the interstate where I am not making any turns, only highway curves, is there anything wrong with it? I am talking speeds like 50-70 mph.
View 12 RepliesGetting wind noise from the A pillar drivers side at highway speeds?
I'm getting what I feel is excessive wind noise almost like my window is cracked open. I'm sure this is something the dealer would be able to fix under warranty correct?
So I have a 2007 focus. It develops a front vibration between the speeds of 50 and 65...where it starts to even out a little. I would like to think of this as an alignment problem (i guess we should be checking on the alignment more often) this occurs after about a year of new tires. we are about to purchase new tires for the car again, and i dont want to end up buying new tires every other year for the car.
View 3 RepliesMy daughters car jerks periodically at highway speed. She's been told her transmission is OK and she's not concerned about the car. My wife is very concerned! It has never stalled, and seems to run fine, then a little rough [unless I imagine that] and then jerk, jerk, jerk, and then fine again. She drives an '07 Ford Focus.
