2007 chevy cobalt issue. Not sure what it is?
Today at lunch I put my car in drive and pulled up about 2 feet and the car made a jerk noise and then it wouldn't go when I would accelerate. Then I put it in reverse and tried to back back up into my parking space and the car wouldn't move when I pushed the gas. I turned the car off and back on and put it back in reverse and it finally backed up, but while it was it was making a loud god awful squeeling noise. And now it's sitting. Any idea what that was?

First of all, Learn a few things about MODERN CARS! There is NO GAS PEDAL at all! You only have an "AIR:" pedal! Fuel is INJECTED downstream, and your foot only adds AIR! You have a GIZMO called an IDLE AIR CONTROL VALVE which adds MORE AIR as the computer directs it to do! RIGHT NOW you have a DIRTY IAC valve and THROTTLE BODY! This happens mostly when you use VERY CHEAPO OIL CHANGE SPECIALS! Learn to use only DEXOS or MOBIL ONE 0W-30 or 0W-20 oil INSTEAD. ALL SMALL HIGH OUTPUT ENGINES will DIE from BAD OIL UISEAGE! MOBIL ONE is the ENGEIN SAVIOR of our time! It PREVENTS sensors damages, CONVERTER clogs and BEARING and RING WEAR! And it lasts for ONE FULL YEAR between changes! YOU SAVE MONEY all the way around by USING IT! TAKE $20-40 to ANY OIL CHANGE PLACE and ASK THEM to clean yoru THROTTOLE BODY and yoru IDLE AIR CONTROL VALVE! This is where the FINAL AIR/FUEL mixture is MADE from COMPUTER CONTROLS and O2 senosr signals! bad oil CLOGS IT UP easily! mobil one MAKES no sludge< coke OR varnish and keeps the cleaning-up AS YOU DRIVE IT! see?GET IAC valve CLEANED UP and see what happens!
