But when I accelerate out of the parking lot it hesitates and really sputters. I can ride through the trails fine at average speed but when the road goes up hill it sputters when you put it under load and is sluggish. At one point I got a "check engine" light, I ran the code and saw: P0301 Cylinder 1 Misfire Detected. Pulling back to 2000-2100 rpm still seems pretty darn shaky though. These sensors are sputter deposited directly onto the test.
