I've got a 93 Oldsmobile Cutlass Cierra, and it has been suggested that the problems I'm having are related to my ECU. (description at the end of this post, for those interested) Is there a way I can test to see if it is my ECU? Can I look at it and see something visibly? I bought a $35 code reader and it says my car is fine, if that makes a difference. The short version of my problems goes like this: I can start my car, drive it for about 15 minutes, then it will die as I slow down (i.e. stopping at a traffic light) then I can start it up fine, and when I put it in gear, the engine dies. I can revv it while it is in neutral or park as much as I want, but when I put it in drive it dies. If I put it in drive while revving it, it will usually take off just fine.
