2017 TRD OR Power Loss

I've had this happen on several occasions where I push on the accelerator and the truck does nothing then responds, I am also noticing a lot of engine knock. I have used several different types of fuel and the same is occurring. Any ideas before I go to the dealership where they won't be able to replicate.

 

Stalling for like half a second or 5 seconds?

 

Stalls for a second or so....

 

I think that's pretty normal for this engine. On the knocking, I'm not sure hopefully you get some good responses.

 

I believe it could be the characteristics of the Atkinson engine. It takes a little getting used to. There are times where it's a little scary because you expect instant feedback and it's not there.

 

Isn’t there a cps recall?

 

His profile show's 2017. Wasn't that fixed for 2017? Maybe not

 

Not sure either. Just thought I’d mention it

 

it's a ping or whatever they call it.. it's discussed in the tuning thread in this section. mine does it as well 1000 to 1500 rpms cruising.

 

Mine used to ping on 87. But I see op has tried other fuel

 

these trucks should not have an issue on 87.. no one buys a low power truck to run premium fuel lol.

I run 87 because fuck it.. it's a pinger.

 

Define the knocking? Is it faint and only happens from time to time or is it constant and noticable?

 

mine only does it when around 1000 to 1500 rpms and trans downshifts as I roll on the throttle increasing load.

 

Could just be the Atkinson cycle

 

I think it's poorly executed ECU programming. The 2.7L does this too.

 

I don’t feel this. I always use medium grade, but frankly, I don’t think that makes a difference. I’m just an idiot and like to waste money.

 

The knocking/Pinging occurs randomly sometimes while accelerating, and other times just driving down the road it is very noticeable.

 

Sometimes I feel like my truck hesitates in certain rpm ranges, almost like it's not advancing the timing. It's probably impossible to capture the knocking on video but I'd be interested in hearing it if you get around to it OP

 

you should get a obd wifi dongle and a phone app and see if knock sensors detecting anything
