Toyota - Corolla :: 2001 - Loud Spark Knock / Engine Pinging Noise Under Acceleration
Oct 13, 2015
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?

Had it before, code p1401. Changed out dpfe and it worked for 6 months. Now spark knock again. Now though I have no codes though. No vacuum leaks that I can find. New egr from before I had the problem. I applied vacuum to the green hose and it stumbled so the ports should be ok. Snytime I go above 3000 rpm i get the pinging. I replaced the dpfe again and no difference.

So we finally found a travel trailer and picked it up yesterday. It is a 2008 Jayco 29A. Fiberglass with aluminum frame. 5345 dry weight, so shouldn't be too taxing on the Ex, but we towed it through parts of the NC mountains to get home and on steep grades it would downshift to 2nd gear and I would hear what sounded to me like pinging from the engine.
As far as I know the plugs are original, so should I just go ahead and replace them, or there also a possibility that this is just the notorious exhaust manifold leak? If all exhaust manifold bolts are still intact, is there a good test to know if it is the exhaust? No engine codes were thrown. The truck has 72k miles on it now.

I have a Toyota Corolla 99 that I have owned for a bit over 2 years; it has 97500 miles. After around 2,000 miles after an oil change it starts burning oil (no smoke or smell). I tried to check it often to make sure I am not running on empty. The last time I had to fill it up once and top off a bit another time before the oil change. I recently also changed the serpentine belt.
I thought the serpentine belt was the noise I was hearing when idling. Now, the noise is still there. Does not get worse when accelerating so hoping it is not a engine knock. Was told by Autozone guy that might be the iddle throttle. Hard to describe noise. No clank, almost like something spinning with a noise every 2 seconds.

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?

I was driving my car today, and I stopped at a stop sign. When I went to go, I pushed the gas, and my car revved up, moved forward, then all of a sudden it made a loud grinding noise (Like I was dragging metal sheets), and the gas stopped responding (but the engine was still running). The car still turns on, but whenever the gas is pushed, it doesn't go and makes that awful noise. What could be wrong?

Here's a bit of background on the car itself:
It's a 2003 corolla, 180k miles, and was sitting an entire year. About a month ago, I replaced my battery, and did an oil change. After the oil change, I started getting a few random symptoms:
loud ticking sound in my engine
check engine light with code P1349, VVT System (but it's disappeared since)
oil light on and off, intermittently.
With a bit of research on the error code, people have said to replace the VVT-i actuator. Do you think this solenoid has a large potential as the source of the issue? I purchased one for around $100 from Autozone, but am having a tough time removing it from the engine.
If you think this is the issue, how can I remove the solenoid? Do I just unbolt the one bolt I see on there and yank? Or is there something else I'm missing?

I have a 2006 Corolla LE with about 93,600 miles.
It was about 16 degrees Fahrenheit this morning and I drove on a cold start, and noticed the engine knock a bit when idling. Later noticed check engine light come on. After the car fully warmed up, 15 minutes later, the knocking seemed to subside.
I don't think I've replaced the spark plugs in the longest time, so could it be this issue?

I drive a 1998 Civic hatchback. Last night while I was driving I needed some gas. I pulled into a station and the only gas they had available was 93 (highest octane). I only ever fill up with 87 or whatever the lowest grade is, so I put 2 gallons in to get me to my destination and the opportunity to find another gas station. Shortly after, I was back on the highway and the engine starts making a loud rattling pinging noise when I step on the gas. I normally might have a low rattle or ping that I've never been able to get rid of, but never loud like this.
Then a few things happened– smoke starts coming out the exhaust, the check engine light comes on, and the car starts to overheat. Seems like it was pretty much all at once, although it was in that order that I noticed... I rolled the windows down and turn the heat on high, but the air coming through the system wasn't at all hot. I got off the highway and as I downshifted, the engine started to smoke a little. I get to the end of the off-ramp and the engine dies. It wouldn't start back up right away but I managed to start it a couple of times (between it dying) to get it to coast into a parking lot. Under the hood, there was coolant everywhere it seemed, but I couldn't see anything else apparently wrong– hoses, etc.
In the end I had AAA tow it home. So, what happened and what I'm looking at now in terms of repairs? I will need to have it towed again to a mechanic if it is something I can't figure out myself.

My Jetta wagon with 131K on it has a ping when I accelerate hard. I know it's not bad gas, but probably a carbon buildup. I've done a few seafoams that had some effect, but not much. I'm gonna do the water spray/steam next. Which components are prone to carbon buildup in these gassers that would cause ping?

I have a 98 Toyota 4Runner, which just started what I'm told is pinging or knocking on "hard accelerations", like accelerating on the merge lane when I see cars coming up behind me in the lane I want to merge into, or going uphill. i have 258,000 miles, and have the SUV serviced regularly and get things fixed when they need it. I told the dealer about it a month ago when I had regular servicing, and he did something to clean the fuel injector, and suggested I try 89 octane (he specifically recommended Sunoco), and if that worked I could try going back to 87 octane (Sunoco was his recommendation again). I did as he suggested, and the pinging/knocking seemed to get better with 89, but returned with 87. I read the Q&A on this, but still have questions. Why did this just start after 14 years? Should I do anything about, in other words is it harmful? If so, what should I do? Does the brand of gasoline have anything to do with this, or anything else for that matter? I am hoping to keep the SUV for a couple more years (300,000 miles), maybe longer.

The car had been idling a little rough lately and I'd noticed a drop in MPG. After trying a few easy fixes I finally replaced the O2 sensor a few weeks ago. The idle has leveled out but ever since then I've been getting periodic hesitant-to-non-existent acceleration. Sometimes it works just fine (better than it's been in years, actually) but then sometime it will take forever to accelerate from a stop.
I'll give it some gas and it will just roll forward at barely more than an idle for half-a-block until something kicks in and it levels out around 30mph. This doesn't happen consistently though and I can't see much of a pattern in when it happens or why. It seems to work a little if I ease into the gas very gently, and it is worse when I try to gun it. I was worried it might be the fuel injectors or the ignition coils.

1987 Buick LeSabre V6 w/automatic transmission. Suddenly getting a fairly loud "knock" from somewhere in the engine area. Only present at low rpm or idle, goes away at higher rpm's. Does not seem to be related to vehicle movement. "May" change some with gear shifting but can not really tell. Oil is full and no "idiot" light warning. Timing belt recently changed. Car seems to run fine, just making noise. Any clues???

Experienced this (Loud engine knock or rattle noise) regarding the service bulletin (T-SB-0010-12)? If so, did you take your vehicle in for service?

I bought my 2014 Corolla new a little over 3 years ago. Yesterday, when I was leaving work to head home I went to start my car and I was just met with my starter making a loud buzzing noise. My lights in my car, car fob, and etune radio were all working properly, but the car was just not able to start! My coworker told me that he heard of a trick where if you knock on the starter with something while trying to start it, it might give it enough of a kick to get going. Whether or not it was coincidence, it did work.
I was able to drive home, about 15 minutes (still daylight, did not need car lights), with no trouble. When I got home I turned my car off and waited for a few seconds and tried to start again. It worked, but it sounded like it struggled. I did it one more time and it failed with that same noise again. I resolved that I would just go get a new battery in the morning.
In the morning, my car was able to start, albeit with some struggle again. I made it all the way to work, and over lunch I was able to start it again and drive it to AutoZone to have them test the battery starter alternator. They told me the battery was too depleted to test it, so I went across the street to Walmart and bought a new battery. After replacing it, the car started like a champ as expected, and I drove back to Autozone to have them test my alternator and starter. The starter came back good, but they said that there was a fault in the test with the alternator. I gave them my old battery and asked them to trickle charge and test it just to see if it happened to still be a good battery that was just losing charge, or if it really was just a dying battery.

My 2009 Toyota Highlander Hybrid makes an intermittent noise when I accelerate from a stop or decelerate to a stop. My best description of the sound is a sharp thud or a dull knock (maybe a dull pop). It happens almost exclusively when I accelerate from a full stop or from moving very slowly. A similar sound happens when I decelerate to a full or near stop. I'm very certain that the sound is coming from the rear suspension or drive train of the vehicle, but I have not proven it. When I'm moving along at normal speeds, I don't hear any sounds and the car feels solid. By pure luck, going over the right sort of bumps causes a somewhat similar noise, but that might be a read herring.
Trips to two separate Toyota dealers have not fixed the issue since it is not easily repeatable. The first dealer tried tightening some bolts. The second replaced one of the front(!) struts, tightened bolts and lubricated things. I have managed to reproduce the issue for the second dealer, but the noise wasn't persistent enough for them to track it down.
This type of SUV should be regarded as all-wheel-drive, but power is mostly delivered by the front tires. The rear tires are driven by an independent electric motor and differential. The front and rear drive trains operate separately; the only mechanical connection between them is the rest of the vehicle. I'm wondering if the electric motor could be slipping a little bit.

My 4.6 explorer has a spark knock noise when hot. When the engine is cold or on cold rainy days it does not make the spark knock noise. I have tried higher octane gas and octane boosters but it does not seem to work. Check engine light is not on and there are no codes. Could I have a bad egr valve or knock sensors with no codes...

I have a 2009 Toyota Corolla and it's making a loud grinding metallic noise on the front left side. It does it while I drive the faster I go the louder it gets. When I turn to the left it makes it louder, when I turn right the noise decreases. PG&E have been breaking the roads by where I live and there's a lot of little rocks I drive thru. I'm wondering if that's the problem?? What do I do?

I am a two Corolla owner. I have a 2004 with 205, 000 kms and a 2010 with 70,000 kms. By far, my favourite car to drive is the 2004. The build quality is by far better. I could list other issues or pt peeves of mine about the 2010.
My 2010 is giving me some issues.
For starters my seat and console squeak like crazy. About 10, 000 kms ago I had the dealer try to deal with it under a TBS.
The next issue I have is that when I turn my steering wheel I hear a low pinging noise!
Lastly, in my trunk that plastic pieces that hold the trunk latch cable to the trunk arm have broken.
As for those plastic pieces in the trunk, what the part numbers might be?

My '01 Corolla occasionally makes a soft groaning noise after the car is in park and turned off. It doesn't happen all the time, and I haven't been able to correlate it with anything. The noise seems to be coming from the front somewhere. I took it to my mechanic but of course it wouldn't do it for him. What might be causing this?
