What's the cause of lose power on a 2008 Saturn
Astra Xr with 89,000 miles. I've cleaned the throttle
body, changed the air filter along with coil pack and
spark plugs. I've switched out some fuses. I've
cleaned the mass air flow sensor. I took it to the so
they diagnosed the mass air flow sensor but i get a
code for the sensor connected with the gas pedal
some where. Anyone ever got to the bottom of this
cars issue?

Mines was the throttle position pedal...the pedal and the throttle are. Wireless.. no wires or pulleys.. Soo mines was sending a low signal and wouldn't go pass 15miles.. went to the junkyard and fixed it.. problem solved.
