Re: 98 XJ stalls need help diagnosing

You should start your diagnostics by checking for any saved or pending Check Engine Light trouble codes.

The symptoms should make you suspect the fuel pressure, the Crankshaft Position Sensor, the Idle Air Controller, and the battery. Test each of these, and also visually inspect the wire connections and wires for each. The Cat Converter has a service life of about 150,000 miles, if you suspect it is old, or failing, you should consider replacing it.
