Hi gus..I got a little problem..hope someone of you can pin point for me..it started couple days ago..I start my car then engine suddently shut off (more like lost power)..from then on..the engine sound little louder (not as smooth like Lexus)..I check all the fuels..all still active...everytime I step on the gas paddle..it sound more louder..and the car seem to speed up a little slower not like it used to be..any clue? also I notice that the a/c fan running the whole time with or without the a/c on (or the heat on)..thanks

 

how many miles on the car? ever had the timing belt changed? water pump?
you could have jumped a tooth on the timnig belt, which would change cam timing cuasing low performance. this could have happened because the water pump might have seized for a second; being driven by the timing belt it could have caused everyting to stall for a second then freed up again.

 

car only had 135k miles..it got serviced at 120k (new belt, water pump..etc) at 97k..the problem just occur few days ago..I believe the fan been running the whole wheather I turn off/on the a/c and heater..and it seem to go louder when I hit the gas paddle..or high speed driving in freeway..the "trac" light was on and off in occasion...is there a way that I can reset the code? thanks

 

you can reset it, but it will come right back. disconnect the battery for 10 minutes then hook it back up.
sounds like a problem you'll need someone to put their hands on to be able to figure out.
