The auto electrician has checked the gasket and connections electrically and it tests OK. The issue I have is why the miss disappears after a short time. if it was a faulty injector would the miss not be there continuously.
yes the valve covers were off and I believe he checked it inside the cover. The mechanic also commented that there was not a return oil flow from the injector. would you suggest that I replace all the injectors to be sure or only the single unit.
none appear to have failed electrically but one cylinder is running colder than the others so we think that is the one that is down. I still do not understand why it gets going after a short period of time.
Thanks for your help. would a engine flush help with getting the carbon removed or is the only option to remove the injector and replace.
Thanks for al your help
