Thanks for the info Stoneage. Very informative. Here are a few problems that need addressing.

1. My 94 Deville (250 G miles) failed the emissions test. I have changed the (egr) valve, (cool ante temp. sensor), (throttle positioning sensor), (cat. converter), and am waiting for the (intake manifold temp. sensor). What else should I be looking at? Also when I had the throttle body off to change the sensor I noticed a build up of carbon in the manifold. I runs rich on start up.

2. The shocks are bad I think, but it could be a sensor of some kind that is not recognizing low speed from high speed, and the top plate is making a rattling noise on the drivers side when I hit a bump. I am unsure what to do about that. Shocks don't come cheap, although I do most of the work myself and that save a few dollars.

3. The drivers side will not unlock when shifting to park but I now know how to fix that. Thanks for that info.

4. When I shift from drive to reverse there is a definite clunk which could be the motor rocking on the mounts or something like that.

5. When I did the code test (55 says current)? And after I start the car (46) keeps flashing after the apply brake to shift message appears? The rest of the codes say (history).

Well, that's enough for you to chew on for now. I would certainly appreciate any comments you may have.

Thanks in advance,

Mazman
