I am changing my cam, so I took the time to do some serious cleaning and service while I had half the motor apart.  When I was cleaning the intake manifold I found that one of the sensors was cracked.  It's the Air Temp Sensor for a 90 EFI system and it has been running rich.  Would the bad sensor be causing it to default to the "safe" mode?

Thanks for any input and does anyone have a spare laying around or know where I can get one?

I would check most local autopart stores Im sure a few of them could order one.  I know most of my local stores are pretty good when it comes to parts for my tracker or samurai.

Not sure about the running rich, wonder if your O2 sensor is out?
