My engine apparently has low compression in #4 (30 psi less than #2). I get misfire cel p0304 at times and idles like crap now. Prior to the teardown, I thought of pulling an LV. I've never done this before. I just thought that we might learn a thing or two from it. Any feedback would be appreciated.
FYI, I believe I've only done like 40 miles since the last ECU reset. And I've never WOT the car since I know she is 'sick' . I also know that I've been avoiding boost. I also avoid driving the car.
