Superchips 91 octane tune
I was accelerating rating up the local toll road hill and she started shutting down , engine light comes on. Nurse it on home and DTC is PO301- cylinder 1 misfire. Replaced plugs, wires and coil pack cleared he code and test drove no problems. Drove to to next day it’s ok, heading home got on the same toll road accelerating up the hill she shuts down again same code and now it’s knocking and misfiring all the time. Time to get a compression check. Anyone have this problem?
