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?
The check-engine light on my 2006 Toyota Corolla came on a couple of weeks ago after I started the car on a 7-degree F morning. Code was P-0171. Mechanic cleaned the MAF and the light went off. Light stayed off 'til I started the car on another 7-degree F morning. Mechanic said that the MAF didn't look dirty, and the readings didn't change after cleaning. No vacuum leaks. O2 sensors responding normally. What's going on? I travel a lot in this car, so I don't want to damage the car by ignoring the check-engine light.
View 1 RepliesI 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.
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 RepliesMy car has 343,000 miles and runs great. It has recently started smoking, but only does it when the engine is cold. I've heard that it could be the rings, and to buy an additive that I could add to the oil. I go through about a half a quart for every 500 miles. I'm not expecting the car to last forever, but I was wondering if it would be beneficial to buy the additive.
View 13 RepliesMy 1995 Toyota Corolla DX with 180,000 miles is missing. It was missing intermittently, especially when idling and cold, and especially when I drove short distances to run errands and then restarted it. It got to the point where it was missing even when warm, and would stall out when idling (always restarted eventually). I took it in to a shop, and they replaced the spark plugs, spark plug wires, ignition coil (which was fried) and the distributor cap and rotor.
All of the low speed and idling problems are solved. However, it now misses intermittently when I drive on the highway, only when giving the car gas at speeds of 45 mph or higher. It doesn't miss when I am coasting, regardless of speed, and doesn't miss at all under 45 mph. This car drives too well under 45 to be headed to the scrap yard yet.
have an 2009 Toyota Corolla 62K miles. If the car sits out 8 hours or more in VERY COLD (zero degrees) weather makes a 1-2 second clashing/sparking noise the split second after turning the ignition on but before engine starts. I tried to attach video/audio. The car starts and runs fine. isn't a ticking or knocking or tapping noise assoc. with bad engine. It isn't squealing noise assoc. w/ serpentine belt. I've been waiting for it to get cold enough to leave overnight at Toyota dealer. I keep wondering if it isn't related to the botched oil changed at the Toyota dealer a couple yrs ago when they forgot the oil & I ran car about 30-60 seconds. At the time, they said all was okay and did compression test (Cyl 1=178psi, #2=175 #3=180 #4=178) all within the normal specs 145-189. I got a 2nd opinion at another Toyota dealer at time who removed valve cover and inspected cam caps and scoped cylinder walls and said all was okay and compression good. No mechanical problems- uses no oil, check engine light not on, etc. What noise is and why just when very cold and car sits out long time?
View 18 RepliesThe rattle appears as I rev the engine at a certain RPM. It happens in every gear. I had the car jacked up and the heat shields checked today when I had my tires rotated. Unfortunately for me my 2006 Toyota Corolla was NOT doing this when I was at the tire shop. I opened the hood and the sound is NOT coming from the engine. It sounds like it is coming from the middle of the car, or maybe the passenger side. I am stumped. I did all the maintenance on the car and everything.

Engine knock on start-up (Lasts one second)
sounds like a lifter pumping up.
Only happens occasionally.
Happened last night after driving 40 Miles and parking it for two hours.
Is this normal? I have noticed this since the first 10 Miles on the odometer. Figured it was the 0W-20 Oil.
My friend has a 2003 Echo with 100,000 miles and it does not do this.
I installed a K&N CAI intake about a month ago; the 69-8757TTK, which is supposed to be designed for our cars. And I noticed that there was noticeable engine knock when driving uphill. My father thinks it might be due to the extra air coming in and not enough fuel. Could this be the issue? Is there anyway to adjust or fix this? Not really looking to do a tune since the car's a 4 speed auto and it only has 130HP so it won't even be worth the money. In reality if I can't find a fix I'll just put the stock intake back on.
View 2 RepliesMy 2011 Camry LE I4 with 21k miles has a slight knock after cold startup, at Idle for a few minutes that disappears after warming up. If you start and drive and don't let it warm up the knock, under load, is more pronounced.
View 3 RepliesI finally made a recording (attached), I would suggest listening to it with headphones if possible. The noise I'm referring to is featured between the 0:28 and 1:00 marks. You can hear it again from about 1:10 to 1:25.
Just to recap:
2014 GX Premium pkg.
4400 miles
93 Octane always
The sequence of events is such:
1- Car is parked overnight in garage, air temperature is 60 degrees or less
2- Start car, pull out of garage
3- Put car in D
4- Drive to stop sign at end of street
5- The transmission downshifts and engine revs slightly as the car comes to a stop
6- After sitting at the stop for a few seconds, foot on brake, engine at idle, it starts to make that thumping/clunk noise
7- Noise stops once I start moving again, and does not come back once the engine is warmed up
Note: This happens whenever the temperature is 60 degrees or below and the engine is cold/car has been sitting overnight. All accessory systems were shut off for this recording/demonstration (no A/C or heat running, no radio or other accessories on).
I recently bought a 2011 460 L, CPO with 28,350 miles. I love the looks and how it drives, smooth! But I do have a concern. Before I go to the dealer I thought I would educate myself from the experienced LS owners. I am hearing a very brief (1-2 seconds) mild engine knock at a cold startup.
This only occurs when the engine is cold and has sat overnight. It never happens after this first startup, even after turning the engine off and then on again. It kinda sounds like the oil isn't getting where it should be for a few seconds. Engine sounds great with normal and hard acceleration throughout the day. The dealership where I bought it is 300 miles away, so I would be taking it to a local dealership.
Now I did hear this noise and mentioned it to the service manager when I first bought the car, and the service manager told me that this cold startup sound is normal. He also mentioned the direct injectors at idle. I guess sometimes it's hard to fully trust what dealerships say. Is he right?
It almost sounds like somebody is taking a small hammer and banging at the plastic cover on top the engine when the vehicle is started new from cold. After about 8 or 9 knocks it goes away.
Taking it to a dealer soon to get it checked.

There was a TSB for 2AR engine, Engine Knock/Rattle Noise at Cold Startup. My question is for those I4 camry owner, do you have these rattle sound when you start your vehicle at cold? I am not sure if mines have the same issue, but pretty sure is I can't find any differences between mine and this clip:

So should I take it to the dealer? Or it's normal?

I have a 2003 Mitsubishi Diamante that I have owned since 2008 purchased it with 60,000 miles on it. Currently has 131,000 miles. I have always kept my car in good running condition and performed all of the scheduled maintenance per the owners manual. Last month I noticed a slight cold knock on the right side of the engine that would go away when the engine warmed up. I checked the oil and noticed that it was a little bit low (maybe half a cm below the lower threshold on the dip stick). I added oil and continued to drive it, still knocking.
Bought some sea foam thinking it was the lifters and sprayed a can in the intake and poured some in the oil. Then changed oil with 5w-30 synthetic, have been driving it for about 500 miles now and the cold knock seems to be getting worse and I can faintly smell burning oil when it is idling as I let it warm up before driving off. By the time I get to work the knock is essentially gone. My oil levels have been fine... My question is, should I be explaining to my wife and fiscally responsible self, that I need to be looking for a new (read used) truck sooner than I had initially planned? Or, is this something that can/should be addressed or just drive it until it gives out...

Yesterday my truck was in the shop for repair. Intake gasket, Transmission fluid change, all heater hoses, thermostat, serp belt and coolant flush. When I picked it up from the shop, which was after closing, I noticed a knocking on start up. From past experience on a different truck, it sounds like a cam that isn't oiling. After a few minutes the knock goes away. I drove for a few miles, turned off the engine and started it back up and no knock this time. This morning I started it, knock was back but went away after a few minutes. Oil was changed about 1500 miles ago. Running pennzoil 5/20 with a K&N filter. Up until yesterday the engine has been completely quiet. Was wonder if something may have clogged the filter or the drain back valve.
Alright so I got a 92 toyota Celica 2.2 5SFE recently and guy before did a head gasket.. well i started to work on the car. fix things here and there. well one issue I cam across was low compression.. 170 170 30 90.. so i was like ok the guy didnt do it right.. took it apart. found out valves were stuck open. So i ordered a remmaned cylinder head to put in and new head gasket set etc.. replaced all gaskets that came with it..
Also put in remanned fuel injectors due to one leaking so i just replaced em all. New plugs, wires, cap, rotor, timing belt, followed the oem manual word for word to install and remove and timing is right. But I got it all back together and ran great. until my tps went out(replacing that soon). Compression is now 180 across the board.
Now I got a knocking issue, Its quite apparent at idle/ low rpm.. solid sound, goes away at higher rpms, gets plenty of oil to cylinder head, started bout 150 miles after finishing. Im not sure where to start.
When i turn on the ac its cold for about a few mins and after it just starts to blow air and its not cold anymore, also it smells funny when i turn the fan on for a few seconds.

1) Engine rattles at 3500rpm. Only at 3500rpm. 3000 is fine, 4000 is fine.
2) Just had my brakes replaced. They knock when I brake moderately, took it to the mechanic, who replaced them. They knock less now, but still knock. The knocking sound is kind of a pop that happens at 1 second intervals.
I recently got a Sonata from my parents when they moved to Pennsylvania. It's a 2007 with the 2.7 liter engine. It has had low oil for some time, so when I got it (last week) I put more in, up to but not above the full line.
It has had now for just a couple of days a very bad rattle, which is barely audible (but still IS audible) at idle and gets very severe during and after acceleration. It remains for some time even after the gas is no longer being pressed, then subsides a bit. I diagnosed it as knocking, but just today the check engine light came on and the rattle got louder.
I don't have another car to drive and I have class in five hours. Should I drive it or call a cab?
