First....So I just installed all new o-rings in my spark plug tubes. Great except I accidentally disconnected two coils during the process and didn't realize it. So...start the motor....it obviously is not running good and I get an Engine light. Well...figured things out...fixed the coils....and the motor is running fine....but still have an Engine light? Can I fix that myself?
Second....since the weather has gotten cold, I'm getting PSM and ABS light on while the car is cold. When the car warms up...lights are gone. Just wanted to check if that's normal or an issue?
