Known Issues
|
|
Common Problems:
|
Early models can experience issues with intake manifold gaskets, exhaust manifold cracks, and aging suspension components. Transmission issues (automatic) can occur with high mileage. Electrical connector corrosion is also a possibility. Refer to manual for specific diagnostics.
|
|
Engine Performance Issues:
