ok i pulled the codes out of my car and it says there is 3 problems. the problems r low voltage at the throttle position sensor and then the other 2 r low voltage at the manifold absolute pressure sensor. does anyone kno y there is low voltage at the sensors and how i could fix it. thanx

I would first clear the codes and see if they come back. If they do, your TPS may be able to be adjusted...but the map will need to be replaced.

How many miles are on your car?

I would look at your charging system. For all three codes to point at low voltage, I would tend to fix the trend rather than the individual symptoms...

first off, let'* follow MOS95'* advice by checking the voltage going into these sensors.

That will give you an idea if the sensor is at fault. The MAP sensor provides data in both volts and HG'* to the PCM, if either is out of spec the PCM will tell you. And the issue with the car could be caused by only one thing.

my car has 190,000km. thanx for the help.

Wow. A gearhead, and this one specifically, agreed with me!!
