ses only came once more, and that was for a coolant sensor. unrelated. I think we have the same issue to a "t". but 3 months no injector or computer problems leads me to believe the issue was resolved by the dde replacement......so far so good.
Check out burger motorsports, the jbd module if you dont already have one. ive "heard" you can set it to 80% and run the poop out of it with no ses or limp codes. All of this after your piece of mind has been restored by a few months of solid normal performance.
