I have a 2000 175 Johnson that idles great in netural, and in forward, but tends to have a sneeze when idling in reverse. I would say it sneezes every 20 seconds or so while in reverse. I have no other issues with the engine running, I couldn't ask for it to be any better, I am just curious what could be the problem, or do I need to be conerned? BTW the gas is about 3 months old, it is non-ethanol gas and it was treated with Stabil fuel conditioner. Any suggestions would greatly welcomed. I would hate to ignore a small problem now and have a huge problem later
