Need help my 2010 journey 4 cylinder recently messed up big all dash lights came on and my car lost all acceleration. Managed to get it home for I was not far from it. Went to start it back up and wouldn't start changed my battery and started up right away but now I have a check engine light on traction control light on and my engine sputters with little to no power and my rpm needle jumps from 0 to 3000 without touch the gas pedal. Please help for I have little money and can do things myself what could possible be the issue? Was told it could be the tps (throttle positioning sensor) thanks for the help
