Running rough, Red lightning bolt comes on on dash. If I turn car off then back on it goes away. this is only when car is cold. It seems to be taking longer to warm up and 2 times randomly on the freeway my temp shot up but immediately went back down without me doing anything.
SOURCE: WILL A Dnr code stop a car from firing
Considering that all of the codes you mentioned had something to do with electrical signals from the various sensors, my bet is on wet connections. Try taking a blow dryer set on low heat to the wiring connectors.
SOURCE: engine shuts down while driving or some times just won't start
since its in the shop right now, have them check the fuel lines and injectors...what could be happening is that your engine could be starving for fuel because of a cloged line or injectors..
SOURCE: Car looses power and a lightning bolt flashes on dash.
voltage lose,have the alternator checked.
SOURCE: 2005 Chrysler 300 codes po300 and po123
The P0123 means Throttle/Pedal Position Sensor/Switch A Circuit High Input.
The P0300 means Random/Multiple Cylinder Misfire Detected
Clear the code with OBD2 code scanner. If it comes back on, you
still have an issue.
