I have an 1989 4Runner V6 that is just SLOW!
I am wondering why this is, as compression is good on all cylinders (~140 psi)
Towing a 2200 lb. trailer felt the same as towing nothing, but it's acceleration is slow. My 89 V6 pickup was nowhere near this slow, so it's not just because it's the V6.
Any ideas?

 

Welcome to the forum. Its called "3.slow" for a reason.

 

I don't get why people call it the V-slow, since my 89 2wd V6 pickup had awesome acceleration and lots of get-up-and-go power that my 4runner doesn't have.

 

The 4Runner is a good bit heavier than a pickup. Especially 4WD vs. 2WD too.

 

not sure but 140psi a hole sounds low mine is pushing just over 200psi a hole had to take the heads down a bit to get them flat agian but not much

 

my 22R powered 2wd pickup could take all kinds of cars in a race. for the most part i wouldn't even attempt something like that with my 4x4.

 

what does the repair manual say the compression should be?

 

my 88 truck with the v6 is not quite slow, its no drag racer but it sure will smoke the tires all the way thru first gear and chirp second. fun stuff

sorry to hi jack but any idea what gears came stock in toy 4x4 v6 axle?

 

Look at the sticker in your door jamb.

 

wonderwagon - according to my haynes manual, for the v6 engine, 3vze your compression should be as follows:

###########################
Compression pressure at 300rpm
Standard 171psi
Minimum 142psi
Max difference between cylinders 14psi
###########################

hope this helps.

The v6 2wd reg cab manual pickup was the fastet vehicle toyota made from 89-93 or so behind the supras, Mr2s and celicas...i've got a v6 4wd and its a complete slug compared to my dads 86 22re 2wd

 

morphine I think you are right. THANKS for the facts I believe the 4runner is just worn out and dying. I dont believe in that V slow excuse!
