Hi, thanks for the ideas as for more info about my car: It is a 1986 GL-10 turbo 4x4. We actually bought it out of a junk yard for $300. The turbo was bad so we replaced it. The car has been doing real good up to this point. We actually unhooked the auxilliary air sensor ( I think that is what it was called)and it seemed to help at first my ECS light went off and everything did okay. Now the light is back on if the sensor is hooked up or not. We couldn't find another anywhere so we are doing what we have to do. This is the only vehicle we have to go 75 miles round trip to work each day. We watch the guages a lot and sometimes I think they are screwed up. The car does have a Digital dash.
