Why does my 2012 impala keeps having misfire issues?
I have a 2012 impala that had all the stabilitrak issues and we fixed that with
new wire harnesses. Then the check engine light came on and car was
idling rough. It was a misfire on cylinder 2 and cost $3500 to fix even though
I am not exactly sure what they did to it. It has been about 2 years and it is
doing the same thing all over again only this time it is misfire on cylinder 6.
Does anyone know what is causing this and if there is a cheaper fix? We
already checked the plugs, wire, and coil. My dad thinks it has something to
do with being direct injection and some sort of carbon build up? Thanks!
Go to your air in take and flow the thing to close to the Motor and there’s a sensor with 2 screws holding it on and the plug to remove and clean it with Carburetter cleaner but all the little motor upwards used toothbrush or something to clean it I think it’s called idlerSensor
Or check your vacuum lines
