1k mi. on new engine, and now backfiring though throttle body.
well, as the title states... im having some backfiring through the throttle body at light throttle/low throttle situations.
before i start throwing parts at it, i want y'alls opinions, and feedback.
i am replacing the o2 sensors, as they were both throwing codes. i have since disconnected both of them, but the backfiring continues.
the motor also bogs way down to almost stalling point before doing so.
i know timing is spot on, i put it all together, and made sure it was. merc225hp(mark) also helped(through email) so i know its spot on.
i also get from time to time, crank sensor loss of signal, and cam sensor loss of signal. so i was thinking of replacing those. along with the tps, as its
condition is unknown(came off the 5.9 tb from jy)
so im kinda at a loss. the truck is about to get a bunch of new electrical parts, unlesss i can pin-point whats causing it.
