Ok, I understood what you posted about tempature. My brother drove it for a little over a 1/2 hour before he brought it over to him last time they plugged it into the inspection computer. I was told its not saying which sensors are not being read. I dont believe the engine light has been reset, but my alternator went and was replaced in July...I had to reset the clock & radio stations when that happeded... and then there was an engine sensor (he's not here to ask which one - it was not the o2 sensor though - I know that) in September because the engine would seem like it was suddenly shutting down for a second and then pick back up (while driving down the road,) replacing the sensor resolved that problem. Other than oil changes, brakes pads and tires, thats been the only recent work on the car.
I put my subaru on the road in middle of January, and parked the mercury. I drove it a couple times for approximately 25 mile round trips during 6 week period I was not using it daily. I did start her at least once a week, and let it run for a bit, because it is outside and I didnt want mice or critters getting into it or for the battery to die. In March, the Subaru's CEL came on, it needs a new cat, so I was going to use the Merc while Subaru gets fixed, but now cant get merc to pass inspection which is now past due. I will ask him again for codes, but he has said to me twice that both the state computer and his tester are not providing codes for what is not ready. I have asked it more than once cause I dont understand it, I would have figure between one or the other he would be able to get some kind of read of whats not ready. Is there any one sensor that does this more frequently than the others? We live in upstate NY and its been between 3o to 70 degrees depending on the day during the past month or so..
Will follow up when I talk with him in a couple hours.
