Question about Hyundai Tucson
If the engine warning light indicates exhaust manifold fault, then it seems to me that that's where they should be concentrating. There could be a crack in it causing the sensors not to regulate fuel delivery properly.
When all power systems go down, that would indicate a battery/ alternator problem or a wiring harness problem to me.
I would stick with the dealer though, since they have more experience than other garages in diagnosing and repairing problems on Hyundai cars.
Good luck with this repair.

Hello! You have certainly been "through the mill"...I'll need a little clarification to get started...I believe the year of your Hyundai Terracan is incorrectly stated as 1994...That SUV was not manufactured until 2001...Please send a comment and I'll fix your vehicle...

T was a typo,please disregard.This will require much thought.It's late now but i will review this tomorrow afternoon.Did they do the engine?PCM analysis first?If they didn't,they should have after the first couple things didn't work.It may cost $90 but could save much more.I am looking at a diagram for another car,many engine operations have mainly the same components,1 thing not mentioned is the throttle position sensor.Took about a minute to see.That would affect the stall at least.If that fixes it,you move on to the next problem.Car repair is a systematic elimination of causes.The throttle position sensor is also an input to the PCM(powertrain control module)which directly affects the rest of the engine operation.Worth a shot at this point.Please keep me up to date if you hear something.When you comment here I will get an auto link to your post and reply ASAP.Good luck! Greg
