    I need help! I have a 2015 Tacoma and I keep getting a #1 cyl misfire code. The truck is running great 95% of the time. I have replaced the spark plug, ignition coil and the #1 fuel injector. I reset the codes and it will come back after about 70-100 miles. I also have the issue that I can start the vehicle and it will shutter for about 5 seconds and I can give it some gas and it will go away when first started in the morings (once at operating temp this doesn't happen). Also when it gets really hot and I turn it off and go back in 5-15 minutes it goes into what I call limp mode and will not accelerate. I then turn it off and turn it back on and the vehicle drives like it should. Lastly when the check engine light comes on I also get the traction control light along with the maint required light coming on at the same time. when I turn out the Engine light the other lights go out as well.
    Anyone have this type issue or have any idea what I should do next?

    Update:
    I completed a compression test and all the readings shows about 150, which is normal. I also did a few combustion leak tests on the radiator and they all passed. I can disconnect the battery cable; the lights go out and the truck will run fine. Today the truck went into limp model again, but it did not go through days of the lights being on and skipping for a minute when its turned on like it has been doing for the last few weeks.
