Toyota - Acceleration - Rav4 - Sensors :: 1998 - At Start Up Accelerator No Longer Has Any Effect?
98 Rav4 (130,000 miles) starts fine, idles fine, runs fine for 30 seconds then the accelerator no longer has any effect. I can put the pedal to the floor, but there is no gas getting to the engine, it will idles but doesn't go. Until it warms up to operating temperature and then it is just fine.
This gets worse the more times I stop for an hour then try to go again - it is better when it is starting from being completely cold.
The check engine light does not come on, two different mechanics have tested it - no codes are produced - the computer thinks everything is just fine. One of the mechanics called his buddies at a Toyota garage in California but none of the 12 mechanics there could figure it out.
Sonata NF (2006-10) :: Acceleration Power Suddenly Lost - No Engine Light
My problem is on wed I was driving my car,when I suddenly lost acceleration power, after pulling over to the side of the road I turned off the car and restarted it. However I still had the same problem with acceleration. After a while of trying to get the car to start I called a tow truck and got it towed to the dealer. When I got there they told me it was likely and issue with with a sensor on the gas pedal and the engine. At the dealership I started the car to show them the problem however the car drove perfectly and no engine light came on.
They told me it was most like what they said over the phone the sensors. However on xmas eve they called me and left a voicemail saying the rear cat had went out and taken out both rear exhaust manifolds and it would coast $3000 to fix. My question is how can all that happen without the checking engine light coming on in the car and the car showing no problems while i was driving it and how did they miss it when I had took the car in two weeks earlier for regular maintenance and to correct a drive belt issue due to it walking after I purchased a new drive belt and pulley.
Prius (2010-12) :: Cruise Control - Car Slowing Down Suddenly And No Acceleration
I have had my 8 month old Prius for a week. I have used cruise control fine before and after the incident. All of a sudden we started slowing down. Doing any thing on the cruise control had no effect. I canceled it. But every time I pressed the accelerator I just got the amber warning light come up and the car beeped at me and no acceleration. The cruise control didn't get the car going either. I had to stop on the motorway. Put the car into park then put it into drive and drove off fine and the car has worked fine since.

I have a Mazda 626 (V6) with about 150K miles and a funny engine racing problem. It occurs only when I'm going highway speeds (for me, 70MPH) and the car has been running for about 15 minutes. The engine will race, then chug and RPMs will drop down again, then it will race, etc. If I slow down, it will stop racing, but often start again as soon as I put my foot back on the gas pedal. If I don't get on the highway (running 60MPH and under), the car is completely fine.
I've taken it to my mechanic twice; the first time had the fuel filter replaced, the second time got new spark plugs, but it's still doing it. What else it might be?
Ford Ranger / B-Series :: Engine Starts To Race Without Coming Back To Idle
2000, 2.5L standard transmission. IAC replaced about 2 years ago, DPFE sensor and vacuum hoses replaced early last summer. Truck has been running just fine until I washed it last night. Went to work, and when coming to a stop and pressing in the clutch, engine starts to race without coming back to idle. Had to turn the truck off in order to get the engine from racing. Same thing on the way home. What else can/should I be looking at? I did not open the hood to wash the engine off, so it can't be water from the wash.

Exactly how much effect does weight have on MPG? I remember reading 1 MPG loss per 50 lbs of extra payload for the GII, is that about right for a GIII? (At that rate, I would get about 1.5 extra MPGs if I was as skinny as Tiffany Yep...)
For that matter, what weights do the EPA use for their MPG tests?

Bought a 2013 Prius V with 3000 miles on it over 1 year. The car has only been driven 1000 miles in the last 7 months or so. I am worried this might not be a good thing for the battery(s)? Is there a Diagnostic test I could request that would determine strength of the batteries? Other hybrid parts?

Just got the 2012 Prius in June and have put around 12,500 miles on it. I have loved the car so much but last Wednesday night I came out of work and the car would not start. Thinking maybe it was just the 12v battery I called Toyota care. After attempting to have it jumped it still would not start. It was towed to the dealership located in Carlstadt, NJ. It has been over a week now and they still have not been able to fix it! They say they have run a diagnostic test on it and nothing comes back fine but they still can’t get it on. They say they are now testing each wire individually.

When start my Caprice (1986) carb-- I used to step on the gas pedal (half step is more than enough) to start the car.
Once the car started it's idling normally, but suddenly after 3 or 4 minute the sound of engine go high idling as if I stepped on the gas and that is remaining for long time even if I step full gas, and if I turnoff the the engine and pull out the key, the car will remain working hardly and shaking like crazy before it completely stop.
What is the problem with my 86 Caprice Brougham? is that problem easy to fix?

Prius (Gen 3) :: 2013 Suddenly Wouldn't Start - Dead Or Low Battery?
My 2013 has been problem free until this afternoon when I went to leave work - it simply wouldn't start, maybe a dead/low battery? It's a 2013 Prius II and just hit 40k this week and now due for service, so maybe I'll have them look into it?
Today was very hot around 100*, around noon I went to get something from passenger side and decided to crack the windows. Instead of going to the other side I reached across the console and pushed start which gets it into whatever mode it's called. Pushed the brake with a hand while pushed button again to turn on and operate window controls. Then I pushed start again to turn car off, which turned off display as normal. When I went to start it 5 hours later I got nothing.
No dash light up, dim dome light, door open light was on with door open so I knew there was some measure of power, I think I saw a check engine light near the door open light lit up at some point in my attempts too. I popped hood open to see where the battery was at, lol, it's not in the engine bay. In my frustration I finally started noticing a "buzz" sound of some part in the engine bay. Tried to figure out what it was - all I know is it's mounted on the firewall in front of driver, about knee height, behind/below the brake and power steering reservoir. I was kinda able to get my hand far enough to confirm it was buzzing/moving/active by touching a finger to it. Was able to get it to turn off with sever pushes of the start button - maybe the car was cycling the different "on" modes without turning on?
So I decided to try and jump the car. Friend who's borrowing a car luckily had jumpers - the weirdest looking jumpers I've ever seen. They were thinner gauge and super flexible, they were also two separate strands instead of being connected like normal jumpers. Anyways, I got nothing out of it. Was about to give up when someone id called showed up - used their jumpers thinking maybe the weird ones were bad. Immediately got a spark when I put the negative on the strut bolt, confirming I had juice.
Prius started immediately as "normal" (no idea how a hybrid starts after a jump...). Stereo was working, headlights, dome lights, windows - basically like nothing happened. I did notice the battery indication was a little lower than normal, but still had just below 1/2 bars. If it were low I'd imagine it would be lower. It never gets above 3/4 bars for me unless I'm coasting down a mountain for a while.
Dead/low 12v battery? What's the part that was buzzing?
Prius (2004-09) :: Pulsing Effect When Turning Right - Severe Steering Wheel Shaking
This summer, my steering rack failed, and I had it replaced with a remanufacutured steering rack. All went well, until a few weeks ago I started feeling a pulsing effect when turning, usually when turning right. On a few occasions, the shaking has become severe. It is a back-and-forth effect, about three times a second. It is bad enough that it has triggered a power steering error on two occasions. I took it to the garage who installed the rack, asking them to have a look at it, and they found nothing. Because the effect is regular, I am assuming that I am feeling the 12V power assist malfunctioning or reacting to faulty input.

My original Yokohama avid s33 is about ready to be changed. It now have over 42k on them. I think I can still stretch it before the winter starts. My OEM size are 195/65/15 and I'm thinking of getting the 205/65/15. According to Tire Dimensions Made Simple - Discount Tire my tire rotation will decrease by over 16 revs per mile. I know the side wall is going to be about a quarter an inch higher about an inch and a half bigger in circumference And the car is going to sit half an inch higher and a wider Width.
Looking for observation/s pertaining to performance, mpg, handling, traction, etc.

View 5 RepliesToyota - Prius :: 2009 - Check Engine Light Suddenly Came On
I own a 2009 Prius (4 years and 4 months old) with about 33K miles on it. Last Sunday while driving the Check Engine Light (CEL) suddenly came on. I made it home and started digging for possible causes - everything from a loose gas cap to a failure in the water pump for the inverter to a 12V battery nearing the end of its life. I've eliminated the water pump for the inverter as the source of the problem since, when I put the Prius into "Ready" mode, I can see movement in the fluid reservoir (when the gas engine is not on) indicating that the pump is working (it had also been replaced under a recall on that water pump a couple of years ago).
I'm down to a loose gas cap (which I checked and tightened) or the 12V battery as possible problems. I've tightened the gas cap but the CEL won't go off and I'm about to replace the 12V battery. Will that clear the CEL? I'm going to take it to a mechanic on Friday morning (my first opportunity - until then it's sitting in the garage) to get a code readout. Could this be something more serious? I mean the car is under 5 years old and has only 33K miles on it! What else could be causing the CEL to light up?
Prius (2010-12) :: Engine Cover / Splash Shield Popped Off Suddenly
Today, on the way to the Lego User Meeting in Virginia driving at 65 mph in the morning on 495 - the oil change access door of my 2010 Prius III engine cover/ splash shield ( part 51410-12101) popped off - it made a popping noise when it broke. Couldn't stop because I was in the middle of a superhighway. It was half way off when I got to the meeting in VA. The Prius is so low - the shield was impossible to reach without a lift. On my way back home to Maryland, the oil change access door fell off completely albeit I didn't see or hear it fall off. My 3 year warranty is up and I have +38000 miles on the odometer so I'm pass the TSB 0032-11 coverage now. I've raised my car on Monday _ nothing else is damage - san a missing oil change access door.
