Had the exact same thing on my '02. As everyone is saying it was my injector o rings. Lots of oil loss real quick! the good news is............you have an excuse for new injectors. At least that what I used to justify them.
Like the title says. I have a Torq 2.2 for sale. It has been on my truck for less than 2 months. Nothing wrong with the unit. Liked it but decided to delete and don't want to stack with my race tuner. $300.00 takes it. Thank you for looking.
