Toyota - Corolla :: 2001 - Loud Spark Knock / Engine Pinging Noise Under Acceleration
My 2001 Corolla w/80k developing a considerably loud spark knock/engine pinging noise under acceleration. It throws no codes but pings like crazy and it never used to. It's happened gradual over a long period of time. I've cleaned the throttle body and have done all regular tune up items with no improvement. It doesn't ping at all on 93 octane, does some on 89 and terribly so on 87. Why is this? Does the 93 octane just act a a richer mixture of fuel to alleviate the ping? Should this sign point me in the direction that it's definately a lean issue causing the pinging?
View 13 RepliesGolf V R32 :: Acceleration Seems Hesitant When Floor From A Standstill
I got a VW Certified R32 back in August and I'm loving every minute of it! I just have two little issues. When I floor it from a standstill, the acceleration seems hesitant almost as if something is holding back the power until I hit about 3500 RPM there's a slight break (as if it were shifting but its in 1st the whole time) and then there's a lot more power available.
Also, when ever I'm shifting there is a slight delay between when I press the paddle or push the shifter. I push the '+' paddle wait half a second or so, and then it starts the shift sequence. Only seems to happen when I try to shift between 2k and 4.5k RPM (4.5k+, the second I hit the paddle it starts shifting). Is this normal? Is this because of the AWD(never had an AWD car before)? Should I complain to the dealer?
Touareg :: Hesitant Acceleration After Stopping At A Light Or Trying To Get On The Highway
I just recently purchased an 05 Touareg V6 and I am a little concerned regarding the acceleration I am getting like after stopping at a light or trying to get on the highway. It seems that it takes this vehicle about 5-10 seconds to realize that it needs to get moving. However, after it does realize what it needs to do, the acceleration is fine. I was told different things such as it could be the turbo system and one thing I find very hard to believe that this is a characteristic of all VW's. I like my VW and don't want to get rid of it but would prefer better acceleration
View 2 RepliesRough - Engines - Storm :: 2008 BMW X3 Hesitant On Acceleration After Driving In Dusty Weather Condition
I was caught up in the middle of the haboob (major dust storm) in Phoenix this summer. I drove through it in my 2008 BMW X3 (40K miles) for about 45 minutes. Ever since, the engine has been idling rough and hesitant on acceleration. I had replaced the air filter which was full of fine dust particles and thoroughly cleaned and vacuumed the internal of the filter housing. I also used Chevron Techron fuel system cleaner on a couple of tanks. The condition has improved a bit but it is still not back to how it was before.
View 2 RepliesToyota - Corolla :: Hesitates On Acceleration Over 60 Mph?
Every time I reach about 64 mph, the car begins to sputter spontaneously. As I give constant gas to keep it at that speed, the car hesitates, as if the gas isn't combusting consistently. This sputter also happens sometimes when I'm simply accelerating for example from a stop sign, however, it is CONSISTENTLY doing it at about 64 mph. I can go faster and the sputtering seems to lessen (at 70+mph, as long as I'm accelerating). Took to mechanic, he couldn't figure it out, although they suggest getting yet another computer.I've replaced:Distributor capDistributorSpark plugsComputer (from ebay, remanufactured)

What could be the cause of this? Have replaced the park/neutral safety switch and the Toyota Mechanic found loose wires on the Master Plug-In and repaired the Ignitor Connector. The computer generates no code to identify a problem. Problem still not fixed. I eventually get it to start but do not know why. Fuel pump replaced a couple of years ago.

View 3 RepliesToyota - Corolla :: 2009 - Lack Of Acceleration Sometimes While Driving
I have a 2009 Toyota Corolla with under 90,000 mi. Sometimes while driving, the car will refuse to accelerate and slow down to about 10 mi an hour. The only way to fix it, is to pull over and turn the car off and restart it. It immediately responds and it doesn't happen again. This lack of acceleration usually occurs in the first 5 mi of driving. I have a new battery...
View 16 RepliesToyota - Corolla :: 2004 - When Shifting Into 2nd And 3rd Gears Over-Throttle During Acceleration
Every so often, my manual transmission Corolla will "overthrottle" during acceleration, especially shifting into 2nd and 3rd gears (and sometimes even 4th), i.e., the engine will race above the usual RPMs associated with each gear, just for a bit. This however, isn't consistent. I still need to check if the engine air filter is dirty, which I suspect could be a part of the issue.
The vehicle has ca. 124,975mi, and only started exhibiting this problem 2-3 months ago, and only in 2nd gear. Again, this issue is very intermittent, and sometimes I can go a week or two without any incidents at all. The regular maintenance (oil changes, cooling system maintenance, etc.) has been faithfully performed according the manufacturer's specifications.
Corolla / Matrix 2009-13 :: Toyota VVTI 1.8 GLI - Acceleration Delay While Shifting
I currently own a Toyota Corolla VVTI 1.8 2009 GLI. I have been racing this car here at our auto drome for over a year. Last race it starting giving me real bad issues with shifting on the track. I can be a 5,900 RPM and shift to a higher gear and the car will choke and drown and it takes forever to recognize I'm accelerating. I know this is because of the computer and the electronic accelerator it comes with ( I can't remember it's name in English). My gas pedal is Denso and I understand there is an adaption that can be done to the cable to trick the computer.
View 14 RepliesToyota - Corolla :: 2004 - Stalling / Running Rough And Hesitate On Acceleration
I'm having issues with my 2004 Toyota Corolla with 118K. Every few weeks, the car will go through a phase where it will stall out, run rough and hesitate on acceleration. Oftentimes it is accompanied with the rotten egg smell coming from the catalytic converter. When I decelerate to a stop light, the car will stall. When I start it back up, I have to rev the engine to 2000 rpm in neutral to keep it from re-stalling. Once I get up to about 10-15 mph, the car will jerk and sputter, and at 40mph, the jerking motion gets worse. If the car doesn't stall it'll run rough and have the rotten egg smell. I'm assuming the smell is from unburnt gas.
I find it happens more often when I don't let the car warm up for a few minutes. I've taken it to my mechanic, and i've gone through 2 MAF sensors, cleaned the throttle body. I changed the iridium plugs at 102K and am on top of maintenance with filters, oil and such. Of course when I bring it to the mechanic, the problems don't show up, and we are kinda blind to what could be causing the issue. Also, if I park it for a day or two after the issue occurs, the problems go away. What to look for?
Ford F-150 - 1997-2003 :: 2001 - Periodic Transmission Leak
01 F-150 7700 ed. I have a 4R100 Tranny with a 139K miles. It has been rebuilt. Ever since the rebuild (over 10 yrs ago), if I park the truck for a week or so or more, I will end up with a decent size puddle of trans fluid underneath the truck. I took it back to the shop that did the rebuild a couple times, but they could never find anything. It leaks enough to where my fluid level drops enough to cause the transmission to slip in a U-turn because the pickup tube becomes uncovered. I have a couple theories, but am wanting to hear from the collective.
Theory #1 When I park it on my slightly sloped driveway I don't regularly use the parking brake, so it rests on the gears, which eventually forces fluid out an overflow or breather tube.
Theory #2 (a very thin one) due to pressure changes associated with the weather, fluid is somehow siphoned out a breather tube due to some blockage internally in the tranny to where it's not equalizing with the outside air and has a high pressure within...
Santa FE SM (2001-06) :: Losing Power And Hesitant - Idles At 1500 To 2000 Rpm
I have an 02 Santa Fe with the 2.7, 4x4. This started a few weeks ago. When it is first started, it cranks over for a few then starts, idles 1500-2000 rpm. It is a little hesitant at first, but will eventually run fine. If I go to the store after it is warmed up, shut it off, then go back to start it again after shopping, it does the cranking over for a few, and when it starts, you can smell gas (strong smell). when you go to take off, it hesitates real bad, backfire rumble through the exhaust, has no power, bucks, and you have to feather the throttle to keep it running. If you put your foot to the floor, it does nothing, 20 mph if your lucky. if you can keep it running long enough without it stalling, which it has done, and hit the highway, and get going, it will eventually work itself out and run ok again. There is NO CEL. It is getting worse.
View 1 RepliesToyota - Corolla :: 2001 - Using Too Much Oil?
I have a 2001 Toyota Corolla. It's been a fine car, but has one problem--since 2003, when we bought it (used by an old lady who drove it only to the grocery store and to church once in a while), it's been using more oil than it should--more than a quart every 1,000 miles. It doesn't smoke, and there are no leaks, so it must be burning oil. My husband says it may be because the first owner (that old lady) didn't break it in according to your recommendations, and we'll always have this problem with the car. What do you think? Is there any way to cure it?

I have 2001 Toyota Corolla which has 100k plus miles on it. I have recurrence problem with car not starting. After i jump start, it works. I took it to mechanic to get its battery(2 year old) and alternator checked out. The mechanic looked at it, and told me everything is working just fine. He started it and i was able to start it. Problem solved for a couple of weeks.
However, yesterday getting out from work, It came back. Had to jump start and make it work again. is there something i am not doing correctly?
Toyota - Corolla :: 2002 - Engine Noise On Acceleration - A/C High Pitch Noise
I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.
Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?
Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?
Toyota - Corolla :: 2001 - Stalling In The Rain
My daughter's 2001 Corolla (3-speed transmission) is stalling in the rain. Twice in the last week it has stalled when pulling away from a stop sign. Both times she was able to restart the car and continue driving. The check engine light is not on (it works). The MAF sensor & O2 sensor (closest to the engine) were replaced last year. Would a faulty coil pack on 1 cylinder cause the car to stall?
View 2 RepliesToyota - Corolla :: 2001 - P0133 Code Comes On
I've been getting a P0133 trouble code on my 2001 Toyota Corolla and am stumped as to what is causing it. I've ruled out the obvious stuff: I replaced the upstream O2 sensor and can vouch for the lack of exhaust leaks, since I replaced the entire exhaust system myself a few months back and checked again for leaks after getting the code a few weeks back. I haven't replaced the spark plugs yet (they're definitely overdue) or cleaned the MAF sensor (I've heard that these could be the culprits) and will probably do both this weekend.
View 3 RepliesToyota - Corolla :: 2001 Car Sputters When Floor It
I've had this 2001 toyota corolla for about 2 years now and its been sputtering ever since i got it. it usually happen when i start the car first thing in the morning, idle is usually fine but as soon as i put it in drive and give it a little gas it sputters, sometimes almost shuts downs. it has given my beautiful wife quite a few scares when pulling out on a busy street, by pretty much stopping in mid pull-out! so later on in the day it isnt as bad, usually just when we gas it to take off or pass someone.
But it ALWAYS does it when we go up the mountains here in PA, sometimes i cant go more than 35mph. Its been 2 years, im tired of this, i just had the second mechanic look at it without success. both times they said i had bad plugs. so i changed em. ive looked in forums and through that i learned that i can clean the MAF, i did, and i think its a little better, but not enough to see too much difference.
For What Its Worth: it consumes oil, almost a quart a week, and that is with an approx 500 mi per week. But no symptoms,(no blue smoke out the tail pipe and no spots on the garage floor)
