HOT bogging, but not at WOT.
misfiring is violent car , engine and shift handle shakes, this is not bogging it is gross misfiring.
flashes code 12s, good
but did it flash code 12s as the engine bogs? the ECU can in fact throw codes, on the fly at ANY SPEED or LOAD, or HILLS.
so why not drive car and let it flash 12s as you drive , and just see if in fact the ECU saw a gross error, on the fly.
on the fly means driving fast, it bogs and bam code DTC 32s flash.
if yes, bingo , it not then we have powerful facts based on that test.
la bomba (you meant this is spanish right?), and meant Fuel pump checked, but what was the pressure, 30 psi is correct as is a new filter.
my wild guess is the fuel pressure is no good. (i always check it, even CAR moving fast)
the pump can go to very low PSI at anytime. for many reasons, even bad wiring as the 2 door car loves to do.
but since it runs ok WOT id not blame the pump (bomb)
when it bogs, is the bog smooth and if you increase the throttle and it bogs, does it catch up, in that the power returns if you just hold the right
foot at a steady 1/2 throttle> ??????????
Im sure its all fueling related
im not sure how you car makes spark, with LNG.
The ECU most be fooled some how to make spark under LNG mode. tricky that would be....
but in Petrol mode (gasoline, ) it must be using the same spark system, is it?
if yes, we can discount bad spark, see my drift?
ok so is bad fueling. Gasoline.
that means its 1 of 3 things.
1: bad fuel pressure, (flow) only fuel pressure gauges work here, not squirt tests, or other guessing.
2: ECU inputs wrong. (any) MAF, ECT , or TPS. in that order, My guess is ECT is ok, because the ECU goes to hot mode at 176f , as it should.
3: Injectors bad. or ECU is not pulsing them correctly. (bad ecu)lots of tests. ask. its all on my injector pages or FSM.
