i bought a 1986 T Type and just want to know where to start with my rough idle. Previous owner claims all stock except for chip, injectors,kenne bell cold air and adjustable fuel regulator. On start up you must give it gas til warmed up. Once warmed up it will stay running but runs rough, tho never shuts off. on highway or normal driving it does fine. I just want to know where to start checking or replacing......... Thanks
