Service Engine Soon

Service Engine Soon
Hello to all,
I am having a wierd problem, which started today. When my cooling fans turn on, so does the "Service Engine Soon" light. When the fans turn off, so does the light. I have noticed the fans are kicking on about 170 degrees and will run for about 5-10 minutes before shutting off. I have a Hypertech Powerstat 160 degree thermostat installed along with the Power Programming Tuner. I removed the tuning and went back to stock, thinking that was the problem, but I am still getting the same result. No codes set in the computer (I was told the "On Board I" does not hold codes in memeory - can anyone back this up?)
Has anyone seen this before. Other than the light, the car runs fine. 95 Z-28 w/auto.
Any help would be appreciated.
Joe

I think I am having the same problem (I think) with the AIR fuse. My '95 Z runs great but the idle rpm seems to be slightly slower than normal and sometimes I think it is going to kill the motor when at stoplights. When I am driving it, it runs fine and doesn't act like it needs a tuneup. What's weird is the Service Engine light stays on while driving but when I am stopped at a traffic light, the Service Engine Light goes off .. Can you tell me where that AIR Fuse is located? Thanks, Robert
