I don't know if you repaired your problem, but I had a problem with a Saturn that would blow the ignition coils no matter whose i put in, I even bought a set of Excell coils and blew them. What fixed it was I removed the coils and the controller they mount on and sanded all the points that it mounts to anything. I went crazy with sandpaper BUT after I put it back together I never had a problem. I put 60,000 miles on it and sold it with no more coil problems.

Just my 2 cent experience.

thank you for responding! I think I have cured it by doing sort of what you said. I took it all apart and then cleaned it good and then put big amounts of die-electric grease between the ignition module and that mount to carry the ground better. So far, no codes on that issue but still trying to figure out the QDM1 error. I get a low trans temp code which I think is a bad sensor inside the trans. Shop told me $385 to change out the sensors inside the trans.....waiting to get paid so I can have them look at it. All the other sensors on that circuit have been changed so I am inclined to think it is internal...

This is a stupid question but you did check and clean the electrical plugs that go into the trans? I'm not familiar with that year but there has to be an external electrical connection for what is in the trans. Can you get a resistance on the sensor? Could it be a wiring issue? I don't know about where you live but the public library around here allows access to ALL DATA for free. It just costs to print the info. I've used it a lot. Just some thoughts....

I've got a service manual for my 97 and it gives the ohm values at different temps, the plug location, and the voltages you should get when testing it.

I saw that the connector was pretty oil caked. I'll pull that apart this morning and clean it with some brake/electrical cleaner and see what happens. The big plug on the front there, right? I haven't been able to test it cuz I haven't had any schematics on how to???

Did you try the library like I mentioned in post #13???? I always buy the service manuals for my cars and use them a lot. I can't give you the specs. cause I don't have the manuals for that particular car. This set of manuals I bought for my 97 was at an Olds swap meet and they were CHEAP. It comes as a 2 book set and I paid $25.00 for both. Worth looking into !!!! Check out e-bay and Craig'* list also. In my opinion the ones from the parts stores (Chiltons and the like ) are not very good for serious work.

Here is another thought. I had a problem with one of my Other Oldsies that it would just shut down. I would get a coolant temp light and code. I knew it wasn't the engine overheating and it wasn't the temp sensor. Turns out it was the input wire to the ECM that was loose. I replaced the pin and it was fine there after. Just because you get a certain code it doesn't always mean what it says.

Do you smell gas in the vacuum lines from your fuel pressure regulator? If you do the FPR needs to be changed.
