Anybody have any experience diagnosing a false "Slow Down" light? I'm quite sure the cats are not overheating. On my '96 USA F355, there are three thermocouple probes in the exhaust, one in each main converter and one in the muffler. Any idea whether I can just disconnect them to narrow down the problem, or will th ECU not take kindly to that. Will it set a check engine light? Or how about disconnecting the buffers that the TCs plug into? Anyone know how the software is written? Thanks.
