  1. I cleared the codes and got the current codes. Current codes are E30 and F47...the car is in the same shape. I decided to unplug the map sensor to see if that would change anything, the car ran just as crappy. I plugged the map senor in, cleared the codes, and now its back to only showing E30 abd E47, this is after is of course after running to operating temp and driving around the block. So im not sure if it is the map sensor or not, more confused than before. The car engine is really is great shape, the vacuum lines are in excellent shape no cracks or leaks that I can tell.. All else I can
  2. Update: I got the all the fluids changed and flushed, all the old gas burnt up at this point. But on my way to get the fluids flushed the car lost all power, and now only seems to just barley coast along.

  4. Thank you very much for info, I'm getting the oil and radiator flushed today and fixing the map senor, battery replaced and alternator checked.

Ill report back, thank you for your help.
  5. I have a 1990 Deville 4.5L 4D sedan I picked up about a week ago, the car has been garaged most of its life and the mileage just rolled over 101,000. Before I picked up this car I know it had been sitting outside a garage for about 6-9 months, and was filled with bee's. Just before I picked up the car they replaced the distributor, spark plugs and plug wires, replaced the main gasket on the bottom of the transmission, changed the tranny oil, charged the battery, and topped off the other fluids. I have run a few oz of seafoam through the brake booster vacuum line to help clear out the cylinder
