I got a 94 4runner 4x4 with 3.0 in it Abd it's extremely weak anything to test or that go wrong to cause that mainly on take off?

Let me rephrase.. I run a 3.0 5spd. The 3.slo is an extremely reliable engine, but it does lack high end power so it can take a min to hit 60, its not designed as s speed demon. But, its wonderful with low end power & can tackle any challenge. But if it feels as if it completely lacks anything, how does she ride? Any check engine codes?

When i did a compression test on my engine, my guy told me that: If you feel the engine is under powered, or your exhaust is blue. Than you probably have compression problems.
But my 3L doesnt have comp. problems and it is still gutless up hills haha

Well my exhaust isn't blue but pretty rusty. I don't know if it has compression problems or not but i am gonna do a test on it.
I was gonna put a tps on it but I read that you have to adjust it you can't just plug it in and go?
Also my on a 94 should I have a obd port to read codes I can't find one to save my life?
Last but not least the oil pressure gauge isn't working on the dash I went to autozone to buy a new oil pressure switch to put in that screws in block and all they had was the one that screwed into With dummy light
What cause rear abs light to come on dash? Just bought and trying to fix everything

Yea that's what I was thinking

I'd do a compression test, make sure each cylinder is optimal. Shes not over heating or anything right? These engines are very reliable but have a soft spot in the head gasket.

No overheating just feels weak but maybe cause of tires and everything
Keep in mind that your opinion of gutless is different than others. I have a beefed up 22re motor, I think it's gutless and pathetic but others think it's pretty good.
If you do a compression test, leakdown test, and your motor is generally healthy then your motor is putting out what it was designed to put out. You may not have a problem other than that you (myself included) want more power!

I thought my 22re was strong compared to this

Best way to test, find a neighbor with the a 3vze and drive eachothers rides.

how to pull codes
Define gutless lol..tire size, trans, timing have a lot to do with it feeling gutless
IMHO in a 2gen 4runner I like my 3vze over a 22re stock vs stock..I personally feel the 3vze pulls harder off the line than the 22re in the 4runner but that's just me

Yes it is a auto unfortunately I'd love to have a straight shift I had a 92 extended cab with 3.0 straight shift and it was quick on take off. How much is it rough estimate to swap to manual? And I dropped it off at shop tonight to get ac fixed and test compression

Not relatively expensive, but also not really worth the time and money to do it, unless of course your AUTO tranny fails.
I've notice that the 3.0L in this 95 I'm working on is pretty low on power - but I've talked with other 3.0L owners, and they are pretty much all the same - no power. It's even worse than usual, because I am at 6500 ft above sea level - and a good (high) cranking compression around here is 120 psi - which would be considered on the edge of engine rebuild territory at sea level, where cranking compression runs about 150-160.
I recently did a timing belt replacement - and here in the high country they usually advance cams to shore up low end torque to deal with the thinner air. It did help with off the line power, but didn't make a big change overall.
The 3.0L v-6 has an intake runner that is tuned for low end power - but it doesn't help much on a small v-6. Most of Toyota motors are designed to build power in the upper RPM ranges, and this motor is limited in it's upper RPM breathing because of the long intake runners. Still, you may find more sufficient power if you rev the motor more that you would normally rev a v-8. Try upping your shift changes to around 4K to 5K rpm, it may help.
Probably, if you don't want to change the motor, you would have to bolt on a turbo to get the kind of power you are used to.
Others have resorted to engine swaps using other brand motors, usually GM. The 4.3 Vortec motors have torque and HP normally reserved for small block chevys, and they are dirt cheap in junkyards. Yes they are a hassle to install, but they can really wake things up performance wise.

What all do you have to change to bolt up a 350 in one?

That requires alot of fabrication, time, and money.
