Attention’22 6mt Owners

I felt something I think was similar (whatever you want to call it)a kind of stutter or whatever… in my 22 w/mt. 2nd and 3rd seemed to do it the most. Unsmooth acceleration…jerkiness..umm accelerative unhappiness. I dunno.
OTT tune made a world of difference.

 

'23 Pro 6MT stock everything suspension, no tune...just had a trip to the dealer for something similar this week. Tech said it was NORMAL and that it was just me feeling the road. I think this is total bull shit. It didn't do it when I first got the truck (2100 miles). You can feel the difference when off and on the throttle (light load typically highway speeds in the 2000-2500 RPM range). He also said my clutch noise was it just hitting the push rod because of the way it's designed to keep people from riding the clutch...I am going to get under there and adjust it myself. Super annoying visit, the tech was cool, but the service guy was a complete dick.

So I am going to try a couple things...first I am going to try using 89 and then 91 octane to see if that changes anything. I will be getting a ODB Bluetooth module here soon and I want to monitor some stuff and see if anything pops on that. I may consider a tune as well.

 

Yep gotcha! I’m at a dead end. That was one of the things the rep genius told me “road turbulence”. His final was differential torque as I have said in previous posts. “Put it in 4WD then take rear driveshaft off see if it still does it”. He insisted it ain’t the motor. Hence no codes. Everybody with this should turn in a claim. I did. Mechanics are good. reps are a••holes! It’s been suggested that I just don’t know how to drive a stick!
Stay out of tha RPM range! Ha!

 

Oh I did 3 tanks of 93 octane. No improvement.

 

Ha yeah just stay out of 2000-2500...that is funny. I made sure to say upfront I have been driving stick for 25 years so that wouldn't even be suggested. I may try another dealer. They didn't even run codes for me or anything. Just said that is normal. I may go see if they have another manual on the lot...not likely and see if I can drive it.

Had to go and crush my hopes huh?

Are you tuned?

 

From the day I traded in my 05 sport long bed for my 3rd gen in 2017 I have had to tease the gas peddle. Gone are the days of push and go, now it's all about threading the needle. The truck has plenty of deficiencies associated with drive train, but it still gets me to there and back. So far !

 

This is spot on IMHO. The pre-ignition symptoms just dont line up and honestly the ECU and input metrics are all over that at the speed of electrons. I just bought my first Toyota truck 21 TRD Offroad MT. I traded in a 6.7 powerstroke. This V6 is really weak. Much less low RPM torque than my 2019 Wrangler. Well sort of. This power delivery curve is mapped oddly. The truck is like stepping on a rotton plum at low speed. However at 60 mph, on a long grade, the torque comes in much stronger in the same rpm range. This thing likes RPM and needs to be driven. 500-700 Rpm matters. For sure, this thing is getting a maguson. I , in several installations, have yet to find a torque deficit that 8pounds of air, crammed down an intake hole, would not cure.

 

OMG, can we once and for all lose the "pre-ignition" terminology from this thread?

NEWS FLASH! I have never heard of any healthy Tacoma engine suffering from pre-ignition, ever! Not saying a damaged engine here or there didn't ultimately die from pre-ignition, but the fact is, if an engine has pre-ignition going on, it will self destruct in a matter of a few rotations and there is nothing you can do about it.

From here on in, please, Please, PLEASE, use the correct terminology, when an engine is pinging, it is "detonating" or suffering from "detonation".

 

OK Time Out
Way to scientific for me. Thinkin you guys are missing the point here! Lets make it simple. Picture straight flat highway. 6th gear.steady 2600 RPM. 72 MPH. Not accelerating. Truck is doing the “stutter”(whatever)!
I can’t picture me or any of you downshifting to 5th to get to 3 grand or whatever out of that 1500 to 2600 range. All I have to say is anyone else having this issue turn in an official claim. Yikes!

 

And to return to your point, if your truck is stuttering at 2600 RPMs, then there is something wrong with your truck, and that something wrong isn't detonation.

 

My 23 6 MT did the slight bucking/stutter thing as well. It seems to have have mostly gone away as the mileage has went up. 4400 miles on mine at this point. Every now and then I feel a slight stutter in the 2000 rpm range, but a lot less noticeable as when new. Driving at 65-75 mph on flats mine is fine. It seems to happen on a slight incline in 6 gear at slower speeds/rpms 50-55 mph.

 

Hmm. At 50 to 55 mph I am still in 4th gear. I don't use either overdrive gear till I am at a 65 mph cruise.

 

AMEN! Horseshoez!

 

Yep, every once in a rare while I hear that wonderful marbles in the engine sound lol. It’s usually when the truck is going up a hill and shifts into second sooner than it should but doesn’t downshift immediately.

 

It ain’t lug……sure wish it would throw a code!

 

Mine only does that when the engine is cold still. Usually on a cold morning when getting up to speed around 35-45 MPH. Goes away once it’s warmed up. Always thought it was a cold start ECU thing. Got better with a tune also.
