i have been having a problem the past two days with my VX everytime i turn the engine on it looks fine but when i look at the tachometer the RPMs look lower than how it use to be before, other thing that happened was that as the RPM's where dropping my lights were getting dimmer.
then also as i am driving and pressing the gas everything seems fine but when i stop pressing the gas the RPM's go down really quick and it even breaks the car a little...
other thing that i noticed is that the motor is quieter and it doesnt seem that forced and also i was driving today like 50 miles per hour trying to speed up a little and the two first bars of the TOD system were on this has never happened unless i press the gas pedal all the way down...
can someone help me?

Thanks

Juan Jose
