Hello! My name is Roy nilsen and I am currently trying to find a 94 or newer 80 series to buy. I have found one that is running very well but is idling rough at times, every other drive brings up the check engine light. I have search the archives and found no mention of this. The individual selling had a mechanic code read with these results: p0300(engine missfire) 301, 303, 304, 305. He then did some kind of carbon cleaning to fix the problem with same results. Anyone have any idea what the fix might be? Distributor, wires, plugs, maybe valves? the motor has 113k and it is a 95. Thanks in advance!
Roy
