I have 95 V-6 3.0EFI 5 speed and it has no power. At times I need to go up hill in first gear. I have had a tune-up which included plugs and wires, head gasket was done, have tried fuel additive. Any suggestions? Thanks

What size tires are you running?gears? The 3.0 is a very slow engine (hence the name 3.SLOW). High milage can cause an engine to be "tired" running at lower compression than it should. There are plenty of threads here that talk about performance upgrades for the 3.0. Some of the best and cheapest things to do would be a cold air intake, headers, and fast flowing exhaust (no cat-converters). Oh and fuel additive is helpful, but you won't be seeing any power gains from it.
Don't worry, it's completely normal to struggle making it up hills haha.

Check the timing. Factory is 10, you can go up to 15 for a little extra power. Make sure your TPS and AFM are in spec. The Factory service Manual can tell you how to do this and you can download them from the stick at the top of the classics forum. Also could be a clogged cat...
Even though it has the name 3.slow, with a 5 speed, its still a heck of a lot faster than a 22re.

The mileage is 163,000. I have 96 Tacoma (4cyl) that goes like a raped ape and i had the cat cleaned out, so perhaps that may help.

163k's not bad. I had 286k till i got a new motor. Yea those cat-converters rob your hp like it's their job, along with a congested exhaust system. As soon as my warranty is up on my engine I'm doin headers back to true dual pipes, and some sort of mufflers.

Absolutely agree with you on this one. Before I put the new engine in I was runnin two of my cylinders at 95 psi ( should be 150 psi at least). And that's just from years and years of running that truck.

have you changed your fuel filter?

congested exhaust system...tell me about it. As my build progressed I was running a 4 cyl exhaust tubing mated to the V6 headers. Finally got into the next phase with the right parts off a V6 4runner. With the larger tubing it feels like a real go-cart now, and not just a push cart. Not sure if the CAT is different. Seems the same size. But maybe cleaner...?
