Sounds like with good intentions, you may have fouled the plugs. Even though you just changed them 5,000 miles ago, I would suggest replacing them with the factory plugs (AC Delco) or better. These cars are very particular about the plugs and wires, and the least little disturbance can cause turbulance in your vehicles run time quality. I would start small, and replace plugs, and see how your bonne runs afterward. If it still runs poorly keep trouble shooting. Good Luck![/quote]

Try checking the fuel pressure to make sure you are running 41-47 psi... You should fall in or near this area..
You can take the module to Autozone and have it tested, But we have seen even bad ones test good, so I'm not sure if that would help you or not...
Someone listed that it was possible that the exahust became plugged up... Might be an idea to have the exahust backpressure tested...
Our cars have been known to kill off a PCM... But thats too hard to say at this point... If you knew anyone with an L27 powered H or C body like a Buick Park Avrnue, Buick Lesabre, Olds 88 from 92-93 you may be able to borrow their PCM as a test.. <--- This would be a last ditch effort tho..

Yep, I sure did, found the tranny leak today too. the hard lines that run to the tranny cooler. there is a bracket that holds them where they do a 90 degree bend to heat to the cooler. One of the grommets was gone, and with the motor vibrating from running on 4 cyl with the failed ICM, the bracket cut into the hard lines...nothing a small pipe cutter, 4 hose clams and a piece of 3/8 fuel line couldnt fix 
Idle still isnt baby smooth as I would like it to be, but id say the car runs great now. Any suggestions on making her run smooth as can be, other than taking 147k off the clock.
