Toyota - Tacoma :: 2012 - Engine Knocking Around 1500 Rpm Going Uphill
Jul 1, 2014
My 2012 Toyota Tacoma's engine knocks around 1500 rpm, going up hill and does it 100% of the time in the summer. This I attribute running the Air Conditioning, but don't know for sure. The vehicle manual states on page 569 that the vehicle can take 87 octane gas. Also on the same page, there is a statement that says: "You may occasionally notice a light knocking for a short time while accelerating or driving uphill. This is normal and there is no need for concern." This seems very strange to me, engine knocking normal? I don't get it.

I have a 2001 Toyota Tacoma that has a knock or ticking in cold weather. The problem starts sometimes immediately after I start and other times it is only when I press on the gas in the cold mornings after a few min warm up. The noise goes away after 10 min. The question I am wondering is this:
1: could it be worn piston rings and the pistons are slapping the cylinder wall
2: is it an oil pump problem or a oil restriction issue
3: is it a valve guide issue
4: with the history of the 2.7 having exhaust manifold issues (poor manufacturing) could a cracked manifold be the issue
I change the oil myself, the oil filters have been OEM toyota, the noise has been going on since 60,000 miles, the truck is at 230,000 miles.

Have a 1995 Toyota Tacoma 4WD with around 230K miles. Recently, it has been 'skipping'. When we are driving or idling, it's like the engine sputters out and jerks along but it never stalls and always starts. Had it to dealer and another mechanic - plugged it in said it was catalytic converter and 02 sensor. We changed those, along with: plugs, wires, air filter, oil. That did not fix it. What this could be. Where else to start to look for this vehicle. It's been the greatest little truck.

All the gauges on the dash will die for a second and the engine cuts out and the car jerks then it will come back on and everything is fine. Sometimes the gauges turn off completely and the car will die and will not start for several minutes. I will try to start the engine but it will not start until the dash lights come back on. The first time this happened to me I changed the air filter and the car ran fine for a month. So when it happened again I took my air filter out put it back in and again the car worked fine for a couple of weeks. Now, It doesn't work to mess with the air filter at all. The car is cutting out more and more.

I replaced my fuel filter on my 2003 2.4L toyota tacoma 2wd. 65k miles. At the same time I checked the valves. No valve adjustment needed. Then i started hearing 4 to 6 rapid metallic clicks from the engine compartment when I start the engine cold. Clicking lasts 1 to 2 seconds. Sometimes happens when engine warm. This fuel filter is not original equipment.

I have a 2003 toyota tacoma 4x4 with the 3.4l engine. Recently I have noticed that while accelerating I am losing power. I first noticed it would surge while going slowly uphill and since it has started happening all the time. I especially notice a serious dip in power during freeway acceleration at around 3000 rpm. The truck has 100000 miles on it. I have changed the plugs, run injector cleaner (the stuff you buy at the gas station), cleaned the throttle body, changed the air filter, and cleaned the mass airflow sensor. I have played a little with the throttle position sensor and that seems to have some affect on the timing of the surge but it is hard to tell. Of course toyota doesn't service the TPS for that year but rather try to sell you a new throttle body $1100.00!!! Could this be the catalytic converter or maybe a faulty injector? Also, I have not changed the timing belt yet.

How long should I let my engine cool down before changing the spark plugs? I have a 2003 Toyota Tacoma 4cyl 2.4l. My drive home from work is about 10 miles and I would like to change my plugs after work but I am not sure how long I should wait before working on the vehicle.

I bought a remfg denso starter for my 2000 toyota tacoma prerunner 3.4L V6. I spent hours without success trying to get the old starter out. Brought it to a shop and had the new one installed. When I do a cold start, there is a screech at the end when the engine catches that sounds exactly like starting a car that is already running. This happens on cold starts only. Warm starts work fine. Due to the fact that I bought this part separate, having to pay to have a new one installed again is annoying to say the least. I spent another 4 hours today trying to get it out without success. See YouTube link for video of the noise. It's actually the quietest one yet.

After having the rear axle seal replaced 3rd time, my 2004 Toyota makes a sound/noise behind the dash, drivers side, in the engine compartment. Noise is intermittent and only when braking. Hard to describe....electronic sound. Brake pedal feels like ABS system is kicking in. But no ABS light comes on. Mechanics all tell me, "when light comes on, bring it back". Had the brake system flushed today? Still makes the noise.

My 4 cylinder Tacoma vibrates a lot when it is idling, especially sitting in "drive" at traffic lights. My regular mechanic has tried various things to remedy it but none has really worked. He suggested the valves may need to be adjusted. Is this plausible? Or is he off-base? And is it really expensive?

My 09 Tacoma 91000 miles- symptom: when idling with foot on the brake, on occasion, experiences engine pause/subtle forward sensation; otherwise drives superb. Service shop said the issue is remedied by replacing the drive shaft thereby switching out the "yoke" which is the source of the problem. Shop said this is a common problem with 09 Tacomas. Does this need immediate repair or can I drive safely?

I have a 2011 Toyota tacoma with 35k miles. Yesterday while driving at about 70-75mph on the freeway with no warning the vehicle shut down and the engine light came on. It made a clunk about the the time it shut off, it wasn't very loud but I could feel it. I'n not sure if that noise was just the vehicle powering down or transmission kicking from the change in torque? I pulled off the freeway, there were no fluids leaking, serpentine belt was in place. The truck will turn over but not start. The check engine light flashes rapidly.

05 Toyota Tacoma without traction control but has ABS. A few weeks ago I noticed the brake pedal felt mushy. I had my wife step on the brakes with the engine running. I could hear a swoosh of air coming from the rear of the engine near the firewall but more towards the passenger side. I did the following tests:
With engine off pump brake pedal and it built preassure and stayed firm.
With engine RUNNING held foot on brake and turned engine off. The brake pedal moved slowly to the floor.
Check the check valve in the brake booster and its good.
So, I replaced the Brake booster, bleed the air out of the master cylinder and bleed the brakes. Now it feels great for about the first 20min of driving but then goes soft again. and I'm still getting the swoosh of air escaping from somewhere in the same place as before.
I'm wondering if I have a vacuum leak somewhere before it goes into the brake booster? the connection is good where the vacuum hose comes from the engine to the brake booster. OR should I replaced the master cylinder?

While driving with cruise control set at 80 mph in my 2002 Toyota Camry, the engine suddenly revved up to 4200 rpm while going up a hill on the freeway. I was wondering if this sudden high rpm could do damage to the engine? The car has 163,000 miles on it.

We've got a 2012 Hyundai Accent GDI. I've been hearing the rattle "ping" when the engine is under load (accelerating hard or uphill). I've read that this is typical for these engines.
I took it to our local Hyundai dealership since it's still under the 60,000 mile warranty. They updated the computer settings and I put in a fuel additive to clean up deposits. They also told me to buy name brand gas from here on out (Exxon, Shell, Mobil) as these engines don't handle cheap gas well.
Now that I've given you enough of a backstory, here are my questions:
- For those that have experienced the rattle "ping", what did you find fixed the problem?
- Any tips or things to look out for when cleaning the throttle body etc?

I had a toyota prius gen 3 last year where it had an engine knocking sound, where I tried every TSB and changed the spark plugs, spark plug cables, intake manifold, engine knots..... etc., nothing worked except the following video which solved the knocking completely with no return.

I have a 2010 Toyota Prius. The other day I was stuck in a traffic jam - under 5 mph for at least 30 minutes.....my engine started knocking/vibrating...once out of the jam, it felt like the engine was "missing"....I took it to the Toyota dealer in town and they changed the spark plugs and cleaned the area...the car runs a little better but I was in a funeral procession yesterday and after about 15 minutes the car was knocking again. What the problem could be? The mileage on the car is 125,000 (I drive a lot!)...

Today noticed a knockng sound louder than the usual engine knock. It only occurs when we put car in reverse. Checked it with the brakes applied so as to eliminate it coming from any source due to the car moving ie axle/drive connections etc. Putting it in D with brakes on, not moving and it goes away. Put it back in reverse and it recurs.
Tried it even after the engine had warmed to temp guage showing half way. Let car sit for a bit (so engine was still warm) and it repeated. Drove for a few minutes and it would not occur. Shut car off for 1 hour, on restart the engine temp was showing it was still warm and the knock would recur in R.

I have 2012 Camry 4 cyl. Recently I changed the oil from 5w20 to 0w20 as recommended for this car. But after I put 0w20 oil in my car the engine started knocking as if there is a continuous slap in the engine. I had ordered this car from the USA but I live in Turkey. Some ppl say I if I put 5w30 oil the noise will disappear. Camry is not sold in Turkey so the mechanics do not understand the problem. What should I do?

About 3 weeks after an oil change, my 01 Ford Ranger started knocking and smoking when I accelerated up hills. I checked the oil levels to find that it was completely empty. Refilled the oil, but the problem persisted. Tried gas additive--nothing. Finally limped into the Ford dealership where they kept my car for 6 weeks trying to figure out what the problem was. After new plugs, wires, MAF sensor, coil, and PCM the problem seemed to be fixed...mostly. Knocking and smoking eventually stopped until I checked the oil levels again and it was empty. Added oil which started the symptoms all over again. Mechanic ruled out blown gasket. Claims knocking and smoking are unrelated (even though they happen at the same time 100% of the time). Smoke is white. Knocking (at its worst) sounds like a bolt rattling around in engine. Car does not lose power, and when I gun the engine it seems to go away. Only happens going up hills (of which Tennessee has plenty of).
