2017 1.4cyl P0301 help!
a girl who needs help because mechanics in the area never really know what to do with my car and I often get misdiagnosed as they’re not used to working on newer Cruzes! (example: intercooler was clogged and 3 shops tried to convince me I needed my entire turbo replaced and they hadn’t even checked the intercooler and I’m only at 100k miles!!)
my car was driving fine, post grocery store I started it and my check engine light and service stabilitrak came on- it was around 85° and very humid, normally my stabilitrak has only ever come on in extreme cold conditions.
I go get the code read- P0301 additional codes possibly not important: U0422-71 & U0401-71 both “invalid data” swapped the coils-no change still cylinder 1 misfire changed cyl 1 spark plugs starts driving fine, stabilitrak still going in and out. I planned to go get fuel injector cleaner and 91 octane gas since I’m sitting at about 1/4 a tank anyways.
about an hour later I come out and start it to go do that and my check engine light is BACK but now FLASHING and now my car is shaking! (solid light and no shaking before)
Gonna replace the rest of the sparks and I guess do a compression test but my question is: Has this happened to you and what ended up being the cause??? Compression, sensors, fuel injector, gasket, throttle??? I’ve never had a flashing check engine light before. (I’m not driving it and haven’t since the light first came on aside from getting it home and the pit stop for code read)
