- Check Engine Light
- Rough idle, hesitation, lack of power

- Clean or replace MAF sensor
- Locate and seal vacuum leaks

Known issues on Dodge
Dodge P0171 on 3.6L Pentastar V6 shares the same intake runner seal degradation as Jeep. On Dart 2.4L Tigershark, the intake manifold flap actuator vacuum hose is a known failure point—it develops micro-cracks that allow unmetered air. On Journey 3.5L V6 (ERB engine), the intake manifold gaskets between the upper and lower plenum are a recurring leak source. On all Hemi V8 engines (5.7, 6.4), check the MAF sensor calibration and intake air temperature sensor—Hemi MAF failures are less common but do occur after 120k miles.
