I have a 1993 4.0L YJ that I am having a tuff time getting it started. I can get it started, but to do so I must put the gas pedel to the floor. I dont have to do it every time just 95% of the time, so pretty much every time. Once started it runs prefect other than it kinda has a low idle. I have changed spark plugs and wires, cap and rotor and changed the fuel and air filter. Any help would be great.
