Rough Idle / Stall on Decel

Diagnosis & fix steps

LOGIC: Exhaust Camshaft Position Timing - Over-Advanced (Bank 1). ACTION: Inspect the exhaust OCV solenoid mounted underneath the front timing cover. Verify resistance (spec: ~7.0–8.5Ω). Clean varnish on the valve spool; execute AVCS dynamic advance test via SSM/scan tool.

Red Seal field insights

Dual AVCS Control: Modern DOHC Boxer platforms use both intake and exhaust phasers. Extended oil drain intervals cause exhaust phasers to stick due to continuous exposure to exhaust heat.
