2008 Toyota Tacoma Engine Noise

I have had my Tacoma for about 2 years now. I keep hearing this engine ping or scrap when i get to about 45-55MPH. I don't have the pedal down all the way, but it does happen while i am accelerating. The issue can happen when the engine is hot or cold. I believe that it is a piston or piston rod that is misconfigured. I have taken it into Toyota to have it looked at many times and they never hear it. Of course when i do a ride along to get the noise to happen its not there. I know that tacomas are supposed to make a lot of piston noise, but this sound didnt start happening until about 5000 miles ago. What worries me even more is that when it is really cold i get a hard knocking sound in my engine that i can feel on my brake and accelerator. Does anyone know what i can do to get them to hear this sound? I am at 25000 miles on my truck and i need them to fix this before my warranty expires.

Try running premium gas if it goes away, if not have them check the valve clearance.

Check engine light went on today in my 2008 tacoma the tacoma has 37000 miles

Stop by a local Autozone or any good auto parts store and have them do an OBII scan for you. Most will do it for free. They read the fault codes and let you know what triggered light. Have them reset the light for you also.

2008 toyota tacoma whistling noise

I don't know how loud the noise is, but its weird that you mention 50 mph. At that speed or above you are keep a constant rpm level. I say this because it might just be your air box loose and the sound of the intake air is making it. A 2008 truck should not have any major problem. Sometimes an alternator will sing or whine but never heard anyone say something is whistling. One other thing is sometimes for some reason ive heard a noise like that coming from the speakers of my car that goes up and down with the speed of the motor, but that was when I was tinkering with speakers and sub outs and amps. Thats all I can think of.
