Engine Mechanical problem
2003 Infiniti M45 V8 Front Wheel Drive Automatic 114000 miles

WHILE DRIVING EITHER AT 45 MPH OR 70 MPH MY RPM DROPPED FROM 2000 OR SO TO ZERO. THE FIRST TIME IT WAS AT 45 MPH AND THE SPEEDOMETER DID NOT VARY. LAST TIME WSA AT 70 MPH AND THE SPEEDOMETER DECREASED TO APPROX 30 MPH THEN THE CAR SHUT OFF. IT WOULD NOT START BACK UP RIGHT AWAY BUT AFTER 5 MINS OR SO IT STARTED RIGHT BACK UP WITHOUT MUCH OF A PROBLEM. NO CHECK ENGINE LIGHT DURING THE INCIDENT OR AFTER

PLEASE HELP. INFINITI DEALERS SAY THAT THEY CAN NOT FIQURE OUT W/O CHECK ENGINE LIGHT BEING ON.

Hi there,

I would start with a scan, as the check light will not always be set when a fault is detected by the ECU. Start here.

Thank you for your help. However what is an ECU. The same as an ECM.
