    I have a 1998 Toyota Tacoma with 2.7 and manual trans. It has developed a bad misfire that seems to be related to throttle position. I tried a new TPS and it didn't fix it. The truck seems to run fine at very little throttle and WOT, but any where inbetween it acts like it is starving for fuel? Code reader came up with O2 sensor code P0135. Truck has 195,000 miles. Any ideas?

    According to my 99 FSM, that code indicates a malfunction in the "Heated Oxygen Sensor Heater Circuit (Sensor #1)".

    There is either too little current or too much current in the heater circuit .
