Thanks Ken. after two days the system has reset and the immobilizer is functioning again.as you were mentioning on the ECU and ground connection I have remove d the negative / battery to reset after priming the engine.oil change throttle body cleaning.spark plug. cleaning MAF, EGR valve as well.what has taken place in the last month is that I'm assuming the manufacturer proprietary software has programmed a maintenance interval code to remind the operator of routine services.do you think it's 25,000 miles or is it 30,000. With these Mitsubishi's. deciding on that parameter of diagnosing the electronics what is your opinion? As far as the engine performance its operating great.except for the remember of the operating system after factory reset.is it factual that the vehicle has to cycle a minimum of 80 miles before reset is permanently coded on memory.or is it like after so many start ups like other operating obd. lastly,today I went too AutoZone and had a free dia. scan and the scanner could not register and codes it just defaulted on error messages. i am thinking of unplugging the sensors at connection. ie trans.mission IAC, TPS, MAF, coolant temperature and oil pressure to stimulate a soft memory delete.would it be the advisable procedure?

If there are no codes and the car is operating correctly you are good to go. I am not sure what else you are saying can you add? What do you need advice on?

Good evening Ken thanks for the return communications. as I completed my inspections I found the issues it was the culprit plugins and someone had altered the rubber insulators that insert into the coil female connections.the service engine light is no longer arriving as of know,i just completed 120 mile reset time memory cycle after factory resetting the computer.by the way do you know how to get access to urban surveillance data in certain locations and businesses here in regional areas if so email more about it.if I do experience any further complications and vehicular intrusions I will contact the membership.best wishes to you.
