Sort of a long story, but I'll try to keep it short. Been going on for a while. (No, I haven't been driving it much) It feels like it running fine. I wouldn't notice any loss of power or rough running at any RPM. I took it to a decent shop, but no not Rover experts and we was stumped and suggested I look into it otherwise I risked just guessing at repairs to rule stuff out. What we both though was very odd was it doesn't throw codes while hooked up to his scan tool. Besides the codes, it's doing an occasional no-start. Plugs and wires are new-ish. 75k miles on it. Codes: P1300 P0300 P0301 P0305 P0306 P0307 P0308 So where do I start.
