Came in running terrible with misfire codes for cylinders ,2, 4, 6 and lean code for bank 1. I'm not sure if the Snap On scanner can turn on a VVT solenoid valve or not, but using the Maxi-... I selected and turned on the VVT solenoid for bank 2 and no change in the lousy idle quality occurred. I then selected and turned on VVT solenoid for bank 1 and it idle changed and became rougher.
I unplugged Bank #2 VVT solenoid and plugged a Bosch style noid light in to confirm circuit, took the single bolt out , pushed a hose to the side and slid the Bank #2 VVT solenoid out within 5 minutes. Ohmed out at 7.5ohms .Using a power probe ,determined power and ground pin sides of harness connector, then jumped power and ground to respective pins of removed solenoid and watched plunger valve actuate. Sprayed it down with brake cleaner and blew it off, but before reinstalling the VVT solenoid I briefly started the engine to expel some oil and of course to make a mess. It took a second one second start up before it expelled oil out of the hole though, but it made a good enough mess for me to decide to put the old VVT solonoid back in and verify it runs like new and watch the long term fuel trims go into negative territory.
Guess a oil and filter change and clean down the oil and she's good to go. I wonder if a BMW or VW would be as Abuser friendly?
