2001 Chrysler LHS, I put new Injectors in and had to pull the Plenum to do so and after putting it all back together and started the Eng. went to 3500 RPM and refuses to go back to idle. It gave a check eng. light with 3 codes. It was posting all three codes as having High Voltage. I changed the ECM and Throttle position sensor and low Idle Solenoid. Still have same problem. Got any Ideas?
