welcome to the board! I had the same problem with my 2000 4runner and I switched out the throttle postion sensor and MAF sensor and it solved the problem. I changed the MAF senesor because I ran a K&N airfilter and the oil from the filter coated the sensor. I hope this helps you.

well i changed the plugs and wires and fuel filter and it solved the miss . but we have discovered a new problem , sometimes it doesnt want to start , you have to try to or 3 times and then it will start , would this be a fuel pump ????

sure you got the wires hooked up right? Distributor cap? Rotor? Possible fuel pump (but not likely) usually fuel pumps work or dont work.
