intermiten miss at all rpm ranges from 3000-5500 (didn't want to try any higher). rpm varies about 200-300rpm up and down while holding a constant speed. when decelerating under 3500r's motor almost falls on it's face then catches back up. also noticed the motor is idling faster than normal. checked the plugs and they are way leaner than normal. bore scope showed fairly dry piston tops. fuel pressure is good, no loose connections. timing arm bolt is tight and has not moved. as for parts that have been changed on the motor, new stator and trigger one year ago, and 2 used s3000 switch boxes same time.
