The intake manifold not likley the cause of a gas leak. these bikes will develop leaks around the float bowl gasket or the accelarator pump diaphram. if bike has been sitting it could be a over flow poblem also.

I have a 2001 cruiser , my husband put in some premium gas and about 4 days later the engine light came on and the code 0171 . would the gas have anything to do with it

Very doubtful. This code is usually caused by a vacuum leak. Check over the engine looking for any disconnected or rotted vacuum hoses. It could also be a leak in the intake manifold gasket.

Leaks gas from under gas tank 2002 road king

You have a hole in your gas tank or your gas lines are dry rotted. If your fuel injected, you should replace your hoses. If it is carbureted, you could have a bad petcock get yourself a bar soap, and we think it's leak in. Just pack it with soap. It's a leak stops. That's where it is. Before you do anything. No decrease it and clean it, so you can see where the leak starts from

Gas leak

Being a 93 model, I would suggest inspecting your fuel tank, rubber hoses in or near the tank, all fuel lines, look for a hole in tank as well. Rubber hoses eventually dry rot, causing leaks. And your tank can and will rust through eventually. This is a VERY dangerous situation as any little spark can cause a fire.

Sounds like a vacuum leak. This will cause the idle speed to be high. Additionally most cruise controls are operated by vacuum pressure. Look around the intake manifold for disconnected rubber hoses. May have popped off from dry rot or stretched out etc. Find the vacuum leak and fix it, both problems should go away.

Goes dead when you stop gets poor gas mileage

Sounds like a vacuum leak to me, check your intake hose from the filter housing to the engine. Inspect for missing, loose or broken clamps (you'll see a dark stripe on the hose where a clamp used to be. Then check the hose itself for cracks. This is a fairly common problem on older vehicles, resulting in crappy performance due to the engine not knowing how much air is coming in.

If that's not it, try checking the smaller vacuum hoses on the engine and any rubber plugs for dry rotting or shiny fittings where something came loose.
