G'day all,
Nice to be here...I'm down South in Western Australia, near Bunbury.
I'll cut straight to the chase....I'm a mechanic, although I've been out of the trade proper, since 1998, but of course still dabble in all things mechanical.
I recently purchased a 2016 Sonata for my daughter with the dreaded 2.4 engine, which, suprise suprise, had the death rattle. I have fitted a 2nd hand engine (quite easy to change out BTW!).
I have a P0193 code.
Engine is hard to start from cold, idles rough, then stalls. Does this 2-3 times, then settles and idles. Can then bring the revs up slowly with no problems, but if I snap the throttle, it dies instantly. I haven't let it get to operating temp & tried it yet.
So far, off the original engine, I've swapped the HP fuel pump, fuel rail pressure sensor, MAF/P sensor, Throttle body, coils, new spark plugs, inlet manifold vacuum valve sensor. The fuel tank lift pump supplies a good squirt of fuel to the HP pump when the ignition is switched on.
I haven't swapped the injectors over yet.
Any ideas please?

 

hmmm...double check all those sensors....unless it is OEM...it is suspect..

I had to return 2 MAF due to not working...

Now I'm OEM or go away...
