Random Misfire...

The Godfather

New member
Hi, I am new to this board and just want to say HI! I have been having a problem with my 99 4Runner. I am throwing codes: P0300, P0302, P0305. Cylinder 2 and 5 fire off the same coil so I changed out the coil with the one next to it to see if it was the coil. The same two cylinders are causing the misfire. HERE IS THE KICKER... ...it only happens above 120KPH (80MPH). I can drive for 2 months at 119 and below but within 1 minute of driving above 120 the light turns on (blinks first and finally will stay on). I changed the plugs and wires. I dumped in injector cleaner and changed the fuel filter.

ANY IDEAS?!? :confused:
