hi guys, i have a 1998 toyota 4 runner 3.4 liter my check engin light comes on when i go over 120 km/h and it comes off when i reduce speed below that. it showed a miss fire on cylindre 2 and 5. i did a tune up , change the plugs, wires, flushed the injectors changed the crank sensor, fuel filter. the mechanic even checked the timing belt to make sure nothing is loose. i truck runs great even over 120 km, but after all this the light keeps on blinking. please if any one has any idea on what the problem is let me know. thank you
