Getting this 2005 or 2007 Chevy Impala for free.
It has a random misfire, un sure the cause
I checked all cylinders compression, all where fine. Also replaced ignition coil, didn't help.
Wondering what else it could be, code only says it's a misfire. Blinking engine light.

If that's the case then you'd have to rebuild the engine and you probably wouldn't want to since you got the car for free. If that's okay then you're going to have to charge checking everything especially wiring and all sensors using some fancy electronic equipment like mechanics as myself have
