2002 2x2 Tundra V8 auto 150K ... codes 1310 1320 1340 appeared with engine light and engine misfiring. while driving I place the truck in neutral, coast, shut off & restart engine and the misfiring stops. This correction only last a few minutes or a few days(which the engine light turns off) before it all happens again. 2 weeks ago I replaced (all EOM) ECU, coils, plugs, the timing belt, pulleys, water pump, cam sensor, & fluids. Now the same problem appears but the codes are different, almost the opposite, 1315 1325 1330!!!!! CAN ANYONE HELP!!!!

Just to understand, you replaced all 8 coils?? The codes your getting are no IGF signal (ign. confirmation signal) coils generate that signal after fire. If memory serves me correctly the IGF grounds are shared for each bank, lay hands on an EWD electrical diagram and find the common denominator
