Are montero's slow?

[All-Terrain]

Ran into a stranger that has a 2000 and he said the power is one thing he likes about his.

So I am thinking there is something wrong. Also gas mileage has tanked from 17-18 to 8-9 since I really noticed it being slow.

That's such a relative statement that it's not even useful. It doesn't mean anything. His 2000 has power compared to what? A carbureted 22R '80's 4Runner? A Landcruiser 80 with 35" tires?

I have owned a '94 Exceed, '97 SR, '99, and '06 Montero. I think Montero's are adequately powerful for their designed task, but they are not fast by any means. They are more tractor than race car, but then... isn't that why you buy these things?

If yours is slow to the point of not being able to keep up with anything, then yeah, it probably has an issue. It should be able to keep pace in traffic, in town or on a highway. You won't be racing anyone and winning, but it should keep up.

How does it start? Does it take a while to start? How does it idle? Any surging? Wandering idle? How does it run with constant throttle? Any thumping? Missing? Hesitation? How does it accelerate? Any lagging?

Dude, didn't your parents teach you to finish your sentences?

I kid, I kid.

@JBThompson I meant "oh my" sorry

Well he said it would spin both rear tires from a stop, and he was at 7000 ft elevation....(out of town er from New Mexico)

Have to be heavy on the throttle in town. Highway is fine, as soon as it downshifts it takes off more than good enough.

From a stoplight it takes flooring it to make it barely keep up with the flow, but as soon as it hits 3000 ish Rpms it surges like it got a huge boost in power. But as soon as it up shifts back to 4th, it takes a lot of pedal to maintain speed.

Starts fine, no big delay or cranking, idles fine now since I cleaned the iac valve. No missing, no roughness.

Now hesitation, no not really, and lagging, well it seems like as soon as it hits 3k it comes alive. Almost like it bogs down at low rpm and has to pull through it to get power.

I am not sure how the torque converter is supposed to act, but it seems like it does not stall at all above idle. Could this be related to adjusting the kick down cable back into spec? On the maximum end of spec.

I know it's not a speed demon, I don't expect it to be. I have driven underpowered cars a lot, this is more than being underpowered. This is more than just a heavy underpowered beast.

Not starting in 2nd, I thought that might be it but it won't barely even go when the switch is switched.

Mine ( 95 SR 3.5 on 32" s) only does 85, but it will do it all day long, empty , fully loaded , clean roof, full racks .....don't matter.

Like I said before, 0 to 60 time Should be around 10 seconds. If it's not then you have something wrong. It seems pretty obvious there is a major issue. However, I am high skeptical of someone being able to spin the tires at 7k elevation

 

[KyleT]

Oh ya me too. I'll time it next time I'm out and about.

Looks like most of the reviews/road tests from the time were getting around 10 seconds 0-60mph for these trucks... but keep in mind that the tested time was done on factory-equipped 29" highway tires... NOT on heavy oversize 31"+ tires. So your truck will probably realistically get to 60mph in 11-13 seconds, depending on how it's set up. Most of our trucks have well over 100k miles now, so the engines are not going to be putting out the same amount of power as when they were brand new.

I also absolutely call BS on spinning the tires at 7,000ft of elevation. Maybe if you're sitting on a patch of snow.

Ok from a slow roll it takes between 15-16 seconds to 60mph.

It feels like there is very little torque converter slip and like it has no low end torque. Once it gets wound up it feels like a whole different engine.

Torque converter stall was about 1800 foot on brake gas pressed In drive.

I might have heard some pinging too, but not certain.

So, what should checking?

 

[Eric M]

That's way too long on the 60mph run, should be around 10 seconds. The torque converter is supposed to stall somewhere between 2100 and 2600rpm. Yours is low. Sounds like you have an issue with your transmission.

 

[ManfromSnowyRiver]

Hmmm, will have to try next chance I get.

Check your timing sprocket on the crankshaft. The downside to this, is it is not easy. You have to remove the timing belt. I would almost be willing to bet my rig that you find this:

Mine had the exact same symptoms. The keyway on the sprocket got wallowed out, retarding the timing by nearly 2 teeth. It also nearly sheared off the key, which would have caused catastrophic engine failure. After repairing this, my power and fuel economy have returned to normal. Check this asap, as a failure of the key will wipe out your valvetrain. Sidenote: if this is your problem, the sprocket will probably take lots of back and forth wiggling to break loose.

From what I can tell, he wasn't having problems with the timing sprocket itself, but just the harmonic balancer. Check the sprocket behind the balancer. The keyway can get sloppy, like in my picture, causing timing issues. You can't tell without pulling the sprocket though, because the key is crescent shaped and sits in a little pocket on the shaft.
