There are two theories...
- Somewhere around the last part touched is liable to be the problem. Infant mortality or improper installation.
- The part is new so must be another failure.
Get the codes. Post em.
I strongly suggest investing in a code reader or durametric s/w. Enables you to have some basis for troubleshooting or for you to learn how long a problem can be ignored or even how to talk to the service adviser and keep the expense under control.
