Hey guys,
My 90 SHO has all of the sudden started to run rough during idle and at all rpms. This just started to happen and it ran like it has always for the last 4 or 5 months since my full front 60k (cam sensor, cps, seals, plugs and plug wires..) Drives like its missfiring or missing a cylinder or two when I try. Codes are 21, 91, 77, 74, 52. I had most of those before this happened, hopefully not the cause. Any thoughts?
