Services Performed
- – Codes P0300 {random misfire} & P050D {rough idle at cold start). Tech unable to duplicate issue at this time. Removed spark plug, inspected and found no damage on plug or valve train. Inspected freeze frame data and found issue is in the first start of the morning, with cylinders 2 & 4 missing. Research shows this is commonly due to a faulty injector. Due to being a direct injected design they are not easy to test and upper and lower manifold gasket labor is needed to complete diagnostic testing. If fuel injector is proven to be out of spec injector replacement time will be needed to complete repair. – Tech removed intake and tested each injector and found nothing pointing to the issue at this time (all 1.4 ohm). He has cleared codes and installed the 44K fuel additive. At this time we suggest driving and if light comes back we will re-check. –
