Intermittent misfire

So two weeks ago I bought a new 2018 Tacoma V6. The first week I had it was awesome. After putting about 500 miles on it I noticed that it felt like it was misfiring under a light load going up a long slight grade. Now it's getting more frequent. I contacted the dealer they can't get me in for another week. I hooked it up to my scanner and no MIL and all PIDs appear to be normal. Any ideas.

 

Maybe drive it a bit more to break it in and try a different gas station.

 

Just keep driving it, mine did it quite a bit until 10k plus miles

 

I have. Even tried putting higher octane gas in it. It has 1,000 miles on it now.

 

You sure it's a misfire and not a transmission issue like most Turd gens have?

 

Welcome to TW
That's what the "ect" button is for or put it in "S" mode and put the limiter in 4th.

 

I don't think it's a trans issue. I can hear the engine sound change.

 

Mine knocks and pings because it's trying to climb the damn hill in to high of a gear.

 

I haven't even made the first payment yet. And it's going back to the dealer.

 

Engine oil level ok?

 

Ya oil is fine. High pressure fuel pump pressure is fine and low pressure pump is fine.

 

Sorry to hear about your issue, let us know what you find out! Welcome to TW!

 

Welcome to Tacomaworld! Is it possible (since there are no codes) that you are misinterpreting the condition by categorizing it as a misfire? Is it just sound difference? Power?

 

Thanks. Will do. I went to the dealer and wanted to get 6 new plugs for it. They told me not to touch it till they can check it out. Going on a five hour trip this weekend. Hoping it don't break down.

 

The infamous crank sensor, maybe

 

No. U can feel it drop power for a second or two and can feel it buck.

 

That's what I wondering maybe crank sensor, bad plug, ignition coil, or weak injector. That's about all I could think of.

 

Crank sensor. Edit: that son of a bitch

 

Most of my experience with faulty crank sensors has been intermittent no start conditions. Not this. But I guess anything is possible.

 

A bad crank sensor will send the truck into limp mode before it stops running.
