Loss of power/bad smell

I was driving to work in my 2001 Santa Fe manual when power went almost completely. Hardly any acceleration and when I stopped after a few minutes there was a very strong smell (rotten eggs). What might the problem be?

One of the things that it could be is that the catalytic converter has rotted away internally. The rust and particle will then clog your muffler causing loss of power. I ran into this at about 140,000 miles on mine. That could be the source of your problem

When was your last tune up?  Need the computer on it.  The rotten egg smell is way to rich of a gas air mix or burning too much fuel. 
Throttle position sensor, oxygen sensor, map sensor or vacuum hose to the sensor is open, shorted fuel injectors, tune-up stuff like cap rotor plugs and wires, fuel pressure regulator all need to be checked for propper operation.

I had the same problem...for me it was the Engine Coolant Sensor (it sends information to the computer). The car accelerated without any reason, stalled, and sometimes did not want to start.

You need to replace tranny, is your check engine light on? if so get codes read for free at Auto Zone parts store,,,Lots of miles on vehecle? Trans fluid should be changed at 40 thousand miles. Most folk dont do this and thats why trannys go out,,,and treating the trans bad like getting stuck in snow and driveing rough all cause bad trannys

hello I am having a issue with my santa fe diesel and currently suspecting that the oil that the service center is using is a generic oil used in both diesel and petrol engines. I am suspecting that the oil is too thin and causing compression in the cylinder issues and can be seen under load on low revs and very little responsiveness from the accelerator and at times the engines misses and has at one point stalled. You may also hear that the engine rattles on acceleration. I am going to experiment in putting in an oil particularly for diesels only and see if that makes a difference. I topped up 500ml before the last service on a 5w-40 diesiel synthetic oil and that seemed to make a big difference. I am guess 5w-30 will be better choice but did not have that sitting around at the time.
Be interested if anyone else experiments with an oil change and it works.

Just got in my 2001 santa Fe tonight. Started ok, then started shuddering and check engine light went on. Didn't seem to want to accelerate. What could be the problem


this seems to be an engine pressure loss. a leakage in the headgasket or headgasket busy blowing. an engine gets it's power through the pressur it builds up. no pressure, no power. a good mechanic should help you. don't take it to hyundai. they will rip you off. shouldn't be an expensive exercise. otherwise it could be the 4weel drive system busy saying goodbuy. a secondhand unit shouldn't be too hard to find. may be a little expensive though. it can also make the car not to accelerate. good luck.
