Hissing noise? Did you check for a snake?

Sorry, I couldn't resist; check for a disconected vaccum line. That would explain the hissing and some vaccum lines are more important than others and could be causing your problem.

Is your jeep fuel injected or carbeurated? If it is FI, then you might check for a loose hose going into the intake. If it is carbeurated, you might check some of those vacuum lines. Best thing to do, is to find someone to help you, then pop the hood, have them give it some gas, and see if you can tell where the noise is coming from.

Check your spark plugs and wires. If they are bad they can cause hesitation and "stumbling".

Best of luck!

It doesn't matter what you drive as long as it is a JEEP.
