ok, I have a 1995 4runner 3.0. I did a compleat tuneup and the dam thing still has hesitation on take off. I was told the the # 6 injector was not firing, so I had it replaced along with the rest of the injectors. Yes all new injectors, and still doing the same thing. It runs great once it is passed the little hesitation. Also changed the fuel filter as well.

New plugs, wires, air filter gass filter pcv valve, new cap, and rotor. All parts are OEM right from toyota.

Please give me your feedback on my problem.

 

I had the same problem and did the same repairs at one point, with no success. Then I heard it could be the EGR, so I removed it. been problem free since. If you need to pass emissions, this is not a solution for you (assuming it is even the problem). You could probably temporarily block it off and see what it does for you.

 

how do you block this off? can you explain to me. thanks

 

could also be a bad tps.[throttle position sensor].

 

This would be easier to test. Just unplug it. If it runs better w/ it unplugged, the TPS is toast. Try this first.

Instead of removing it like i did, you can just plug the tubes for the EGR.
