To those who have driven other 4.7 Toyotas..

I posted this thread awhile back about my 2008 4.7 4x4 seeming sluggish.

Well now that the weather has cooled down my 4Runner does seem to run better, however after driving a few 4.7 Tundras yesterday I realized it definitely seems sluggish compared to Tundras with the same engine. My question is has anybody else with the 4.7 full time 4wd noticed this too? Is it maybe that the full time 4x4 slows down the 4Runner a little? How anybody noticed any acceleration difference between 2wd and 4wd V8 4Runners? Or maybe it is the weight difference between the Tundra and 4Runner?

my AWD v8 is sluggish and mines an 03. It bugs me but theres literally nothing i can do about it without any tuning.

ive driven a few for work, but never noticed any being noticeably peppier than my 06.

its definitely NOT sluggish. if you put your foot in it from a stop, its a rocket.

I drove an '03 that felt slightly sluggish, but it also had 34s on it

I wouldn't describe mine as sluggish, even with 33s. Small power drop, but nothing significant. It does feel more responsive with >1/2 tank of gas, fresh fluids etc.
[MENTION=87687]LTDSC[/MENTION] , regeared for your 35s yet?

 

[LTDSC]

No regear yet. Still on the stock 3.73s. It's not terribly sluggish it just feels like it could easily be better.

Trucks are like computers, your own is fast until you use something faster. The obvious answer is not to drive someone else's truck and you'll be happy!

I notice a decrease in performance in cold temperatures with winter gas.

Definitely agree with this, if I put my foot down it'll fly. Less so now that I have much heavier tires, but still quite quick off the line.

I've always thought my V8 was sluggish. But that's cause i'm used to my 500+ RWHP G8. Then I go back and think of how much power my 3rd gens had....

I have spent a bunch of time driving an 06 GX with the 4.7 and an 04 Sequoia with the 4.7 and they are all so different in their own way. Also spent a couple of months in a V8 4Runner so I have some thoughts. The GX is definitely not fast but the torque feels excellent and it is so insulated you can barely hear it which makes you think it is slower until you look at the speedometer.

04 Sequoia feels totally different like less torquey and more power coming on a bit later.

4Runner with the V8 feels like a muscle car to me honestly, great engine note and fun power. Run a tank of premium through it and see how you feel, winter gas is AWFUL.

 

[94toy22re]

Tundras came with 4.10 gearing vs 3.73 in a 4runner, that will defiantly make it feel faster

 

[Bob22222]

If anything my bone stock 04 with 200k is too fast. I agree with lolrax above run premium gas for several tanks after you figure out what's ailing your rig. If the ambient temperature thing is real and not in your head then in my limited experience of over a half century at these things you most likely have a temperature related issue with a sensor or control module component. Not necessarily one involving measuring the engine temp but could also be some other performance regulator circuit that goes haywire when hot. I've also seen issues with grounds and other electric connections that create excess resistance or an open circuit when hot but not cold but these are generally filthy, loose, and or oily contact points. Personally I've never in my life been able to notice a performance change in hot or cold weather. Accept it's way easier to blow em up extreme heat. Hope you can follow this with an open mind and good luck

 

[Bob22222]

...I forgot to ask? Are you certain there are no restrictions in either your exhaust or intake systems? And that you are in fact getting a full throttle signal to the signal to the ECU? Have you checked the TPS and MAF as well as the cable to see if it's fully opening the throttle when the peddle is fully depressed (kind of obvious but worth a double check).

 

[Bob22222]

I agree. Kind of nice we don't have that up here they tell me. Too rural to much altitude I guess.

That explains why my brother's 03 Sequoia felt faster from a stop.

Thanks everyone for the replies. The difference in gear ratios could certainly be part of the difference I'm noticing. I had not thought of that. I have ran a few tanks of premium (not back to back though), but never noticed much of a difference. I have looked for obvious intake or exhaust restrictions, but found nothing. This would be something obvious like a dent or pinch in my exhaust or something stuck in my intake box right? I was told on my other thread to check to clogged cats, but admittedly I haven't looked into that.

I cleaned my MAF recently. I have not checked TPS. I did run a Bluetooth obd2 dongle for a few days that said my throttle % with my pedal at the floor was only 73%. However a google search revealved this might be normal not to have a 100% reading. I would assume I am getting a full throttle reading to the ECU since the shift points are close to red line. But, how would I verify I am getting full throttle? [MENTION=134328]Bob22222[/MENTION]

Thanks y'all for the help.

I recently changed my spark plugs at 147900. It could be in my head but the engine sounds and feels more responsive now. It very well could have been the first time the spark plugs were changed. I get my bonus in Feb, and I'll be installing my DT headers then. I drive a BMW 335xi as well and while its considerably faster, I don't feel like the 4runner is any slower off the line.

Sounds l ike throttle at 73 present might be your issue. I am sure mine will reach red line a 3/4 throttle. These things really do have a lot of get-up and go when running right . I check the shift point at nearly open throttle next time I'm out with it. But that won't me for a few days as I'm off on a holiday trip. I'm sure you have, but I'll ask any have you check ed intake for obstruction. As for the throttle valves I'd try and get my hands on a factory manual for that info. Also there a member whom goes by the handle of Blackworks Sync, a Factory trained Toyota tech who seems quite insightful, I he might chime in if he sees this post. Or you can try tiPM him as he seems like a rather nice sort. Again good luck with your quest and stick with it. Remember: anything can be fixed. One clue is it's something that's not growing a code. That and you report normal performance other than a lack of power is what points me toward clogged breathing or a throttle issue. I'm certain things like your pugs and wires are past there serviceable limits, correct? I'm not sure how weak a spark has to be to affect performance that much or likewise throw an ignition fault code of some type but maybe something to look into (spark intensity my old mind is slipping on the correct term here).

 

[Bob22222]

Tried it today. No problem reaching red-line thru the first three gears and nearly there in 4th which was fast enough for highway 40 approaching Lake George. Throttle not at full could be your issue?
Also, I meant to ask, you have checked for resistance (heat build-up) in all your gear boxes and driveline/wheel bearings, right?

 

[Dpassmore]

The awd makes it feel sluggish Drove mine with the front driveshaft out and felt totally different. Gas mileage didn't change much but felt a lot better.
