i have a 91 4runner that i just rebuilt the motor 3.0 and i have to floor it 90% of the time im driving on the freeway to keep it going, and to get it to 60mph just seem like it takes forever... any ideas? i have looked at the cat and it looks good, not sure what it could be.. no check engine light.

 

good to see another new member thats local! have you checked to see if your throwing any code? this a auto or 5spd and are you running larger tires?

 

Check your timing. You can advance it a little to get a bit more power out of it.

 

OK i had this similar issue, i had bought the 4 runner and did a complete tuneup, and still didn't help, a complete lack of power.

My fix, i change the fuel filter, its kinda hard to get to but once i changed it was a huge increase in power. my 4runner had 132,000 and i believe what looked like to original fuel filter.

so give it a shot only a few buck and some time can make all the difference. hope it helps.

 

kool thans ill do the filter this weekend...

its an auto and it has they are 31 10.5 tires.

i set the timing where they said to put it and it was almost ready to die and ran like crap so i advanced it a little area but guess i should go a little more,

 

let me know how it works out

 

i took the motor apart except for the pistons from the block. put all new seals and had the valve job,, did a valve adjustment and new timing belt, when i put it back together i double checked the timing before putting covers back on. so i wouldnt think its the timing unless u can get the crank 180 out but i cant see that happening until u put the belt on.

 

got a fuel filter and changed it and took it for a quick spin... seems to helped and it feels like it has some power back, ill find out next time i go on the freeway..

 

update.... so i also ended up doing the tranny filter and adjusted the timing again.. i can now be doing 65 and not all the way open to keep it going... its running good, just have to figure out the 4wd now....
