leak down test reveals: valves=good, rings=good what the hell is going on with my car, i have a jwt ecu and my fuel goes off the chart on the dyno sheet, after each pull the car shuts off and wont start for fifteen minutes, car sat all night and still has same behaviour in the morning, i dont understand how my compression is low but no valve problems or excessive blowby, could a valve stick while under load and cause it?
