What are the best Buick repair shops?
RepairPal Certified shops can diagnose and repair your 2016 Buick Encore. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Hello, what testing has been performed thus far? Yes, you have a P1101 code, but there is troubleshooting to be performed. What led you to replace the PCM?
Typical areas to check would be:
vacuum lines for leaks
the engine air intake plenum
intercooler hoses
Anything air intake related
The problem is not likely computer related, but instead physical component related dealing with air coming in and engine vacuum.
I would recommend consulting a shop near you to help diagnose your concern hands on.
