A bit more of information. Last night before i reset the computer codes, when the car was idling. I could barely touch the gas peddle and the RPMs would jump to 2000+, this morning after resetting the codes it only jumps to around 1,500. This is the same problem that was happening with the previous ECM before it died out.
Another thing is, the check engine light and coolant light are constantly on. But the car has coolant. Which makes me think the ECM is messing up and not reading properly. Hoping the scan today helps a bit.
