on the freeway at about 55-60 any thing over half throttle it surges like it cant figure out what gear to be in and from a dead stop it has a bad shutter, the tran fluid was about half quart low so i topped it off and it is a little better, from what i have seen online it cold be plugs and wires, throttle position sensor need adjusting, and it needs a fluid and flush thanks james and it is a 3.4 4 spd auto
It's worth changing out the plugs and wires. They probably need to be replaced anyway and are pretty cheap.
I'm guessing no check engine light, since you didn't mention it. I'd check the fluids again, replace as necessary. Clean the MAF while you're there too.
it final threw a code po306 miss fire in #6 so i am going to do a full tune up and see what happens maybe some new wipers to :) poor 4runner
Let us know how the plugs look, but I'd venture a guess its the 3-6 plug wire. It's probably not arcing against the valve covers or intake, but just not getting enough spark (or any) to cyl 6.
I agree with Sean on this, give it a tune up, clean out the throttle body and see how she performs.
all fixed new plugs and wire runs great now, the plugs were shot for sure prob the origanal ones
Awesome! Glad that helped!
