So you have a P0300 and a P0301 or just a P0300?

Also what engine do you have?

Miles?

Maint history?

 

P0300
6CYL
120000
I purchased the used 2012 Tacoma from a Toyota dealer 1.5 years a go.
Since then had a oil change and multi point check at my mechs shop.
I have been getting lower gas mileage lately.
thanks

 

Kinda late on this post…but I dealt with a p0300 on a 2012 2.7. Truck went into limp mode…I could stop and turn the engine off and restart, might not go out again for 5 or 50 miles. Put on a cheap coil (still $60) issue remained. Bought an oem coil and new plugs (just because I was already under there). New oem coil and plugs didn’t fix it.

Bought an oem injector and the problem hasn’t come back in around 1000 miles. I’m hoping it took care of it (knock on wood).
