  • 2013 Chevrolet Cruze LTZ RS: 1.4 Turbo
  • 120,000 miles
  • Dorman Valve Cover installed
  • PCV Fix Kit V3 installed

Check engine light is on, rough idle, and the only code showing is P0102, I have replaced and done many things on the engine and the code still showing and MAF reading is 0.1g/s.

This is the list of things I've tried:
  • Dorman Valve Cover and PCV Fix Kit V3 installed at the same time.
  • MAF sensor replaced.
  • MAF sensor Wiring harness visually inspected.
  • No vacuum leaks on intercooler and tubes/hoses
  • Crankcase resealed.
  • Crankshaft front seal replaced.
  • Oil gauge and cap O-rings replaced.
Compression test results:
Cyl1: 120psi
Cyl2: 120psi
Cyl3: 120psi
Cyl4: 150psi

Any ideas?

Could it be the turbo itself? or hoping not to be the ECU?

Thank you!
