I think the cruise control box might be in a different place on the V6's. I just replaced the MR on my employees V6 sedan and the relay was right there in the driver side foot well with no obstructions. Just removed the old one, put in the new one and I was done. Took three minutes.
Hopefully this is what fixes it. Car keeps shutting off on him when it warms up and then it's hard to restart. Before he asked me about it he replaced all the plugs and wires, the dist cap and rotor. He then took it into Schaller Honda and I had them do the ignition switch under recall even though it was done before, but still had the same issue. This is the only thing left that I think it could be :crossesfingers:.
