I have a 2001 toyota prius. When I start the car and press on the gas pedal the engine rev's but nothing moves and there is some clatter from the engine. I can put it in B mode and drive it a short distance, but that's it.... The engine light has been coming off and on for a week now. It makes a loud audible tone and then I turn it off and back on and then it stops.
View 5 RepliesOk, did an intake manifold cleaning on my 99 Accord the other day, and now I have problems...
Long story short, some time ago my car started to have a very rough idle. Took me awhile to find the problem. Turned out the air hose, between the filter and throttle body, had developed a big hole on the underside. So I replaced it and while I was at it used some throttle body cleaner, spraying into the intake manifold chamber. Lot of junk blew out the tailpipe. The car ran much better, but the idle could still be a little rough. I ran it that way for awhile, and finally the other day decided there was probably still some junk in there and it was time to really clean it out. So I took ff the throttle body and intake manifold housing. There was a lot of junk in there! The small intake on the passenger side was completely clogged shut. (I understand this isn't surprising on these cars.) I used a bunch of rags and 2 cans of Valvoline throttle body cleaner and a lot of elbow grease and cleaned it out. I was thinking to myself that whatever I didn't get with the rags flushed through OK, but I didn't want to take the whole intake manifold out.
So I put it all back together. (I took a video before I started, so I'm pretty sure it's all back together right.) But now I have problems. The car starts. It idles fine mostly, but can be a bit rough. But the trouble starts when I put the pedal down. If I do it in Park, well, if I push it quick the engine just dies. If I push it slow, the engine revs then quits, revs and quits, over and over. Similar if it's in gear. If I push it hard, the engine stalls. If I push it gentle, it revs up, but chugs along a bit.
I've run some seafoam through it, thinking it was clogged up with all that junk, and sure enough, lots of smoke comes out, but nothing is improving so far. What have I done wrong?
Requiring that the brake pedal be depressed in order to start the engine can be a nuisance, say if the driver is out of the vehicle and the passenger wants to start the engine to run the A/C, etc.
There is a workaround though. Press the engine start switch once to go into ACC mode, then press and hold it for 15 seconds and the engine will start without the brake pedal having to be pressed.
I purchased a 2001 Prius with 123K miles about two weeks ago. I knew the HV battery was shot when i purchased it. I decided to see if I could rebuild the HV battery on my own.
I'm very mechanical but not the brightest bulb in the room when it comes to batteries and anything electrical.
So here is where I'm at so far:
- I removed the HV battery.
- safely rested it on 2 horses (I used horses because it would give me easy access to the bottom to remove the bottom screws)
- Removed all 38 modules from the battery pack
- cleaned the busses in vinegar
- inspected each wire that connects between buss and the nut.
- tested each battery ( one of the batteries tested at -0.1, the others tested at 6.8)
- I don't know how to load test the modules, so I couldn't tell if they would drop dramatically under load, so I ordered 38 used replacement batteries off of Ebay. (Gen II)
- these replacement modules were about a half inch longer than my original modules.
- The replacement modules arrived. I cleaned the terminals, tested each one and installed them.
- Connected the battery back into the prius.
- Installed new 12V battery from the Toyota dealer.
- The Prius started right up.
- Drove it around for the first time for about 10 minutes.
- When i was driving it, the monitor in the Prius would show the engine running most of the time but sometimes it would show it charging the HV and other times charging the 12V. the engine would shut off at stop lights and resume when I pressed on the gas pedal.
- while driving back into my driveway, all of the warning lights came on and the battery fan kicked into high gear,
- I can't remember the code I pulled but it was in reference to the cells being out of balance I think. I'll have to check it again tonight when I get home.
- I removed the HV and tightened the nuts around the busses hoping the issue would be resolved.
- I was able to drive it only a few minutes before the issue returned.
other issues I noticed.
While waiting for the replacement batteries to arrive, I did the following:
- changed the cabin filter
- did an oil change.
- changed the tranny fluid and removed the tranny pan to clean out the slime and clean off the magnet.)
- changed the rear brake shoes.
- changed the front brake rotors and pads. ( they were in awful condition due to sitting so long)
***when I pressed on the brakes, only the rear brakes seem to engage, not the front. I never attempted to bleed them because I know only the dealer can do that)
Its a 2005 model with 45000 miles on the clock, so low mileage for the year. The problem with it is the engine starts up ready fr a journey, and as soon as the accelerator pedal is pressed, the engine cuts out.
View 7 RepliesI just bought a used 93 accord. The engine is in good shape and runs smoothly most of the time, but I have two issues.
First, when I start the engine cold, there is a very loud belt squealing for about 3 or 4 seconds. Is this a common problem and, if I isolate the belt at fault, what should I do about it?
Second, the engine revs (both audibly and on the tach) when I press on the brakes. I've been told by a friend it might be a vacuum leak?
I have no codes on screens, engine revs and gas mileage has gone down to 30 mpg from 40s this summer. The toyota service adviser said the poor gas mileage was from running the heater since it is around 20 degrees these days in minnesota. My innova scanner shows no DTC's. But my question is do I need a scanguage II or other scanner to get the battery codes? Am I missing them using the innova scanner? What scanners are available for 2001 prius.
View 5 RepliesI have replaced the computer in a Honda Civic twice. The first time the car was acting like it wasn't getting power;the engine would rev when the gas pedal was pressed but the car would not go! so the computer was replaced, and two weeks later,t he same thing happened. They said it was a short and would not replace the computer-it was our problem. Finally, they agreed to replace the part. Got the car back, fixed a ouple of othere things and now, two weeks later, the same thing is happening. Car acts like it's not getting any power, and this time the check iengine light came on. The car has a new altenator, new battery, and the after-factory radio has been removed..
View 6 RepliesMy 02 BMW 525i engine starts to stop running when the gas pedal is pressed. The engine starts and drives fine when the engine is cold. However, after driving for a while like more than 20 miles, I mean when the engine warms up already, the engine suddenly stops when the gas pedal is pressed, like stopping in the traffic light or STOP sign and starts to drive. I replaced the idle air control valve, but it does not work. What should I check next?
View 7 RepliesI was wondering if this problem is the "Barking" noise that keeps coming up the search or is it another problem. I will include a link to the video down below.
To start off, the Prius is 2010 Prius II and has 120k miles on it. Great Car. Only other problem was AC compressor dying at 90k.
The chirping noise happens when the brake pedal is pressed and does not go away until the release the pedal. It makes the noise regardless of whether the car is on or off.
It makes the noise when the car is stopped and or when the mechanical brake engage at between 0 and 6 mph.
Noise does not occur when the brake switch is removed. Not valid solution since the brake lights will stay on. It does not affect the performance of braking.
Here is the link to the video .... .... ....
Today I faced another problem i just try to start my car but, due the dead 12v battery it didn't start so i pressed the BRAKE PEDAL until it reach the bottom, again i tried to press but its not going to the bottom why was that, is it due to dead battery? And last time i called an automobile expertise to jump start my car. They check the voltage with a digital multi-meter and he said me if you jump start even you will get this problem again until u replace the new battery. but i said him it doesn't matter do a jump start and finally it was ok . Now again I faced the same problem and this time i am going to change the battery.
View 1 RepliesI've bought a brand new 2012 Prius C 3.
This morning I was trying to back out of a parking spot and put it on a reverse after starting my car. As soon as I my car started moving forward and hit the curb right in front of the car. I couldn't believe my eyes so I put the gear back to Parking and back to reverse, and as soon as I touched gas, it again accelerated forward.
Toyota Corolla 93, manual transmission so there was a problem with idling, while it idles, the engine revs up but im not pressing the gas pedal at all. found out it the vacuum hose was broken. we fix it, buy a new one and now the engine dies out. change the air filter. The car still dies out. so the car either dies out or bad idling. what do i do?
View 5 RepliesWe have a 2004 Honda Accord V6 with 178,000 miles and the car is giving us some issues. We can drive the car for 10-15 minutes with no issues. Then when we push on the gas pedal, the car will not go any farther and the engine just revs. If we turn the car off and restart it, the car will continue to drive. There are no check engine lights on the car. Could these be a transmission issue?
View 5 RepliesIt's a 2003 Mountaineer with a mechanical throttle not drive by wire. For about two weeks while idling in park or in gear but stopped in the drive-thru, the engine revs upwards of 1200-2100 rpm. Runs fine normally, no check engine light, no misfire and doesn't matter if the A/C is on or not.
View 5 RepliesI have a 2010 Prius and have been driving several for the past 7 years.Yesterday, I was driving on the Expressway at 60 mph and all of a sudden I was momentarily stuck at 60 as if I was in Cruise control which I wasn't. Gradually, I was unable to accelerate when I pressed down on the pedal, lost speed and cruised over to the side of the road as if I was out of gas which I wasn't. I shut the engine off, waited a minute and started up again. I continued on my journey without a problem. When I reached my destination I shut down the engine and re started 4 hrs later and drove home 120 miles without a problem. What is the cause of this and is it still under warranty. I have 50,000 miles on the vehicle. May I add, this is the first problem ever encountered.
View 13 RepliesI just picked up my new 2014 Chevrolet Camaro with the V6 and 6 speed manual transmission. If I just punch the gas pedal when in neutral, the engine almost dies for just a second but then rev's up normally. It seems like a burst of gas chocks out the engine. I have tried the same thing in other Camaro's and the engine rev's up normally as soon as you punch the gas pedal.
