My wife and i have noticed over the last few months that our 08 has been revving higher, (much higher), than it used to when driving uphill. It has 65 k miles.
View 5 RepliesI've recently purchased a used 2008 Prius with 77000 miles. I was a bit apprehensive but have started to fall in love with this car. After running some errands yesterday, I heard a strange buzzz, coming from the middle of the engine compartment. When I'm in the car is sounds like it is front of me, but seems to be more in the middle when you pop the hood.
And when I'm accelerating, there is now a strong hum almost like a revving sound and it increases the faster I go. I am also getting the Maint Reqd light flashing as I turn on the car, but it goes away when the ICE kicks in, just started this in the past week. I have put about 500 miles on it since I bought it and I did buy an extended warranty.
I am getting between 41-44 mpg, depending on traffic conditions, around town, so the MPG, so far has not been effected.
I know nothing about vehicles as far as exhaust and tire size. But what i want to ask is what is causing my 2007 ford f150 4.6l to rev up while in drive while im just costing. see i was at about 20-30 miles per hour and almost to 2 rpms and repeatedly my truck would rev in the range of 20 to 30 miles per hour for about 1 seconds but would go back to normal after that rev. I rely on my truck for work and also while I was in Park at a target parking lot my truck began to rev up Wow and park I don't know what is causing this....
View 3 RepliesThis truck has been giving us problems off and on for a while now. Whenever I am sitting at a stop light for example and the truck is in drive but I have my foot on the brakes it acts like it's trying to lunge forward and the engine is revving and shaking the whole truck. My husband just drove it this morning and now whenever it gets really wet outside the truck doesn't want to go anywhere. He said he was flooring it and he was only going about 20mph and the engine looked to be shaking bad. I have no clue what could be going on?
View 6 Repliesi own a 2005 f150 supercrew fx4. Today as I was attempting to go out of town I was accelerating up hill and heard a noise, sounded like air coming through a window seal or scratching, which is not the problem. The noise only came on when i increased the acceleration, there is no power loss, the truck still accelerated properly and had good power, just that the noise came on. so i returned home only to hear the problem on flat land also, when pressing the gas to accelerate. The truck seems to idle fine and have no problem with low acceleration.
View 2 RepliesI have a 2008 XL 4.2 auto trans with 60,000 miles on it. We purchased a new travel trailer with a total weight just under 5000 lbs that we pulled for about 2000 miles this summer. On the last trip we noticed the truck was missing pretty bad going up hills or under load. After we got home I started to notice the miss at times even not towing. Did a tune up with Motocraft plus and wires and seems to still have a miss at an idle and very low RPM. What would be best to check next?? Would Coil be logical?
View 10 RepliesHave a problem with a stutter when I press the accelerator while going up hill. I even had this problem driving on a flat road but that was a 1 time thing and happens every time I go up hill. Had a coil replaced that came off of an '04 because one of mine went bad which caused it to shake whenever I came to a stop. Wondering if the coil has anything to do with it... 2007 5.4L ....

I had a misfire under a bit of a load (acceleration) and up hills. I changed spark plus with OEM Motor craft ones, truck ran super nice for a couple week.
Had the engine light flash, slow down and the RPM go up a tiny bit then back down and the light goes off
Now I'm back to miss fire different location, and a rough idle. I've swapped coil packs around and the miss fire stayed on cylinder 4.
Spark plug screwed or injector or ?????
2004 F150 FX4 5.4L. I drove from Vancouver to Edmonton and back this week and I started to get some issues. If I'm in overdrive at highway speeds, from about 90km/h to 120km/h give or take, which would be around 1600-2100rpm, and then I try to accelerate, sometimes on flats, rarely on downhills, but always on uphills, the truck will begin to jerk fore and aft. It feels like it's something through the driveline, either the driveshaft or the differential, but I really can't say for certain as I'm stuck in the driver's seat while this is happening.
If the truck downshifts or if I take it out of overdrive, i.e. getting the revs up high, the problem is no more. Other than the issue I'm having, it operates perfectly so this is very odd. I know that overdrive isn't a hill climbing gear, but normally an engine in the wrong gear will simply lug along until it's downshifted. The entire truck jerking shouldn't happen.
On my way to Edmonton, I noticed that this would cause one single, minor jerk. This is my way of describing it, but it was like the driveshaft had spun freely and then promptly re-engaged with the differential gear, causing a clunk. I doubt that's actually what happened, but I'm just trying to explain the sensation. It kind of feels like trailer jerking.
On the way back to Vancouver, it was a lot worse. Like I said, the whole truck would be jerking about once per second but there was one time that I found the sweet spot and it began jerking rapidly, twice per second. I threw it out of overdrive to stop this but the vibration caused the check engine light to flash a few times but it went away and didn't stay on.
What I might be up against? Been doing a little research. Seems as though this is common and it's supposedly the spark plugs, but those only have 50,000km on them.
My truck decided to have some issues last weekend coming home from a friends house. After being on the road for about an hour the truck shuddered, lost speed and was incredibly sluggish trying to get up the hill. It flashed the CEL and then went out. I was doing about 75 with the cruise on.
After slowing down to about 60 it stopped the shuddering and resumed operations as normal. Until about 20 minutes later when it repeated the above.
The next day I grabbed my reader and found the P0302 and P0306 codes. I cleared the codes and took it for a "test" drive up and down the mountain to see if it would trip the codes again. It didn't flip the codes. I thought I might have been dealing with a "one off" issue and left it alone for a few days.
Two days ago the CEL light came on and stayed on this time. Sure enough P0306. Cylinder 2 did not throw a code this time. After doing some research on here I ordered two new COPs and bought a mechanics stethoscope and some new spark plugs just in case.
The stethoscope confirms that cylinder 6 is having some issues. The COPs came in today so I'll take it apart tomorrow and see what I see. I'll be looking at both the COPs and the plugs to see what may be causing the problem. The "nice" thing about this is that at least it's one of the easier COPs to get to.
Should be a nice day for working on the truck.
I have 160k on my 2005 prius. When letting off the gas peddle in DRIVE the motor is reving up to 4k with out the trans kicking in and moving the car. I have replaced the 12v bat, cleaned the t-body and mass air sensor.
I took it to the local toyota dealer for a recal and now they have had the car for over a week. I am being told it is the floor peddle sending a false voltage to throttle body. I highly doubt that this would not make the care go and not just idle up to 4k.
2006 F150 Triton 5.4 Motor... It's been over a months journey with fixing this truck....
How it started: had an oil change, a while back, on long drive after, check engine light started flashing as I accelerated up hill so I pulled over and in a while it was ok, but couldn't get on the gas too much, or it would cause that flashy light thing.
So fast forward to now, after driving it with an intermittent miss for a while, was driving it to work and the miss became a shudder, and she stopped going over 30-40, and runs extremely rough.
Steady but loud idle.
Replaced all plugs with motocraft plugs and new coils all around. No change.
Finally hooked it up to a computer and got random misfires, now it's saying
P0174 bank 2 too lean,
But it's bank ONE that's the only side misfiring.
Here are the freeze frame details:
Frame 1 Mod $00
MIL Status Off
Troub Code P0174
Abslt TPS 24.3%
Eng speed 1665
Baro PRS 71 kpa
Calc Load 100%
[Code].....
I have a 2005 F-150 5.4L 2WD 90K miles. I started getting a misfire and hard jerk when going uphill. No codes for a few days but misfire got a little worse and more jerking at full throttle acceleration or level throttle up a hill got codes p0300 and p0171. I replaced the fuel filter cleaned MAF and changed plugs Motorcraft plugs (none of them broke during replacement). Miss got worse. Missing at idle and no power 3K rmp to get to 40. Only code pulled was p0171. Replaced upstream O2 sensors and COPs. Will barely idle now. Dies when put in gear. Full throttle barely moves forward a few feet just sputters. Checked vacuum lines cannot find anything. Only code I get is P0171. Fuel injectors next? Or shop?
View 3 RepliesI just bought this car last night from a guy with a dealer license. The car was used, so he sold it with an "as-is" statement. I've read there is a 2 day law to return used cars, but he never gave me this option.
I test drove the car but nothing appeared wrong except the heater did not blow hot, thought the car wasn't warmed up. May be unrelated. Anyways, driving on the interstate I noticed he pulled the battery before selling it to clear the trip memory, and all of that information. So I asked him and he said it was for a small part he installed (he showed me, it looks like a thermostat of some kind with a hose coming off of it, he did not know the name).
I am afraid to drive my car on the highway and if I am damaging my car by driving it I want to make sure I hold the auto care shop that put the wrong size tire on my car responsible.
I have Bridgestone Ecopia EP100 BL tires size 185/65R15 on my 2007 Prius that I got in 2010. Because of a nail in one tire I had to replace one of the tires two days ago. The technician said they did not have the exact same tire any more but he would replace it with something comparable.
The next day I drove 2 hours on the interstate and the slip indicator light kept flashing, it felt like the engine was revving a lot and/or the transmission wouldn't shift when I got to highway speeds, and it was a little scary. My first thought was something with the new tire since I had absolutely no problems before.
I've noticed that my car is struggling a lot to climb uphill. I am not seeing any signs yet but I hear the gas engine running hard all the time going 30mph-50mph depending on elevation. Battery level on the monitor is always one or two purples when climbing up but it charges pretty quickly downhill. Should I risk driving the car anymore? My next destination is Yellowstone and Banff National Park so these driving conditions will continue.
View 19 RepliesOur 2005 Prius with 160,000 miles is displaying warning lights and the gasoline engine is reving at times and not shutting off when the car is at a stop light.
The dealer says it is throwing a P3000 and P0A80 codes. I asked for subcodes, the dealer doesn't know what I am talking about.
The dealer wants to replace the hybrid computer for $900 and if that doesn't fix it they want to replace the hybrid battery for $3500.
Today I was driving up to the highlands, and there is a hill I have to climb called 2 mile hill, it's an 8% grade, I started the climb with 7 green bars on the display, and the engine revved to what sounded like full pace (5000rpm) but I paid attention to the battery and it was actually being charged despite the situation. I got to the top of the hill and the battery was showing all 8 green bars. I'm shocked because I was going uphill at 65-70 MPH and it fully charged the traction battery.
I thought I heard a couple years ago that every couple months, the Prius will do this thing where it will fully charge the battery or something like that because of memory effect of the cells? Why it did this?
I've bought a second handed European Prius 2en Gen from year 2006, the car is wonderful and I simply love it ! I wouldn't change it for anything, but yet I have some problems with it.
When I start the car I get the Red Triangle on the front panel, and exclamation symbol, a VSC symbol and an engine (?) symbol on. On the Display I always have a black bar on the top with a car and an exclamation point on it. Both can be seen int the pictures below....
At this point the car runs normally, the only things I notice are :
1 - When I stop the car (without shutting him down) I notice that the consumption of fuel is at 99.9/L because it is charging the battery, which is already full.
2 - The back-right ventilation fan of the car (on the passenger seat) is ON even when the Air Conditioner is OFF.
After a few miles (I don't know exactly when it happens, sometimes it happens when stopped, sometimes when on the road), the car beeps and then it shows a, on the same black bar on the display, a message saying "Problem", after a few seconds I get a Battery symbol on the right of the car with an exclamation point symbol.
At this point the car starts having the following problems :
1 - The motor begins to speed like if I was at full speed on the highway.
2 - I simply can't do an uphill, the car won't pass the 20Km/h speed, if I gain balance before arriving at the uphill, it will start losing speed until reaching the 18-20Km/h.
At this point I really don't know how to solve this. I only know that, the Toyota Representative here where I live (in Portugal), ask me for 2,975Euros (almost 3,263USD) saying that it is a problem in the Hybrid System. But yet it seems strange because from what I know, if the Hybrid System was compromised, the car wouldn't start at all.
Does changing the 12V Battery on the back would solve this (even knowing that the Display shows a fully charged battery ?) ?
I found recently that my 04' Prius' engine easily goes higher rev than before (based on engine sound pitch). It happens mainly when cold start, go up hill. After warmed up and on flat road, it goes back to normal. Overall, still in great condition at 211K. MPG stays at 46 on meter when temp is around 45F with 50% highway drive at 100 miles/day. I suspect the serpentine belt slippery or something. What do you think? I think the belt is original. I bought it used at 104K.
