Hi everyone, I have been having a serious issue my Sonata V6 2004 model...the car was one of vehicles affected by the flood's in July 2017 and up till this moment the vehicle is still not running
Changed all the censors e.g MAF, Shaft position censor, serviced the engine and injectors but still not running though it started but always going off and never stable.

Pls all the gurus in the building your experience and advise is highly appreciated.

Thanks in anticipation

Have you considered getting a complete engine replacement?

Brain box or ECU suspected

I have considered that also the engine is pretty weak before the flood but was still running smoothly. Smokes on cold morning start after warming up it stops

You ought to have checked the Crankshaft position sensor before lodging a complain long here... Brain box is always the last thing to consider after everything else have failed

I guess I never had proper knowledge on to go about it but it was actually the first thing the mechanic told me to replace and also the ECU or Brain Box was already submerged in water, was totally fried

Your helpful advise is highly appreciated

Was the brain box programmed specifically for your car?

Also did the mechanic work on your engine, if yes, does the. Engine use timing chain, if yes then let him reset the timing

From what it is the vehicle is a free code so recommended brain box was the one without code besides the timing was checked and confirmed to be ok, the issues now is that the vehicle starts but doesn't run smoothly and goes off immediately I engage the gear into drive or reverse.
