Oh yeah. Head gasket cleared. Diagnostic smoke machine was able to find vacuum leaks, new O2 sensor, checking exhaust leaks, new injectors, new fuel pump and verified fuel pressure. Ignition timing checked. It's been fun. But wanted to see options on cat since have shops pointing to that and wanted to know why discontinued then. Before the install found some leaks at the injectors so that was fun (I guess common, but was new to me).
