I'm getting a p0300 code on my 2011Chevy Cruze. 1.8L manual transmission. The data shows mis fires on cylinders 1&4 ~ 20 on each. I replaced the coil pack May of last year, GM part. Along with the CEL the stabilitrac and traction control light is on. I also have an intermittent issue of crank no start when the car is warm. The car will normally start after I pull the ecm fuse for about 30 seconds. I have checked and cleaned all the chassis ground terminals and I added a 2ga ground between the engine and battery. Any help or ideas would be appreciated. I replaced the plugs about a year ago and I checked them yesterday and they look good other than there was a little soot. The car has 130k miles an is used about 20-30k a year.
