Hi friends I have a problem with a Panda natural power the customer complains that the car is perceived of minimal bouncing while you ride, and then cold just set in motion and passed to methane and irregolarissima then warms up and is fine.And was in another workshop where the year to clean the injectors of methane, but 15 days is returned as it was before,and went away again, where they had cleaned before the injectors, and put by unscrewing the tube of the metanodal flute with a syringe of the fluid inside avvitarono again put in motion and the car went well again for a few days then the problem again,back again there told him that they were to replace the injectors of gas.
Now it came to my workshop to replace the injectors, but I would like to be sure that they are first to replace, and then I would like advice on what to do because I have never replaced injectors, cng on these cars and if they are easy to remove.thanks
