establish a starting point: - pull all connectors with the spring clip and clean any corrosion off the connectors and item terminals (CAS, PTU, MAF, Coolant Temp Sensor, AAC, Air Regulator, FICD, Injectors) - test the injectors with a multimeter while the connectors are off. They should measure between 10-14 ohms - set the idle and test the AAC solenoid - do a compression test -boost leak test and fix any vacuum leaks *If your valve covers are leaking, they can let oil collect in the spark plug galleries and when you pull the plug it will be soaked in oil. Can also be rings etc.
