First time posting in this OT but I seriously need help on this one.
I have a 2000 Hyundai Santamo which is giving me a big problem: car turns off and stalls like crazy while the engine is cold. It takes like 2 or 3 times or turning off and then turning on before the car stops doing that, instead the engine starts vibrating and the RPMs are quite low. Worst is if I push the acceleration pedal the RPMs go even further down and sometimes it turns off. This problem disappears after a while, when the engine gets it average temperature.
Now, we honestly don't have the slightest idea of what is happening. My mechanic changed the spark plugs, we checked the fuel injectors, we cleaned all the sensors, changed the air filter and we still have the same problem. To be honest, this is driving me crazy.
There is a thing though: when we disconnected the MAP sensor, the engine stopped stalling and the RPMs returned to normal plus the acceleration issue disappeared. We changed the MAP sensor but the problem returned as soon as we connected the new one.
Any idea what is happening?
