Before you replace the ECU, make sure your ISC (idle speed control) is good. It's pretty well documented that if the ISC goes bad it can fry your ECU. To test the ISC go to this website http://www.stealth316.com/2-isc-iac.htm The website is for a Dodge Stealth, but the info also pertains to the Montero. Good luck
