Disconnect the battery cable, wait 5 min. then replace battery cable = Computer reset. Keep in mind the engine management system's PCM will lose the information stored in its memory when the batteries are disconnected. This includes idling, operating valves and any fault codes detected. This will have to be re-programmed into the units memory. You will experience surging ,hesitation ,erratic idle and a general inferior level of performance. The PCM will learn on its own if you do nothing. This takes about 2 or 3 days. Quick fix is start engine let idle until normal operating temperature is reached, then run RPM's to 1200 for 2 minutes, then drive vehicle for a minimum of 5 miles at varied driving conditions. This will complete the relearnig process for the PCM. PCM=Powertrain Control Module.
