There are a few options you can try to find this information:

  1. Check the owner's manual for your car. This should have a section on the vacuum diagram and other technical information about your car.
  2. Contact a Oldsmobile dealership or an auto parts store and ask if they have a copy of the vacuum diagram for your car.
  3. Search online for a copy of the vacuum diagram. There are many websites that provide technical information and diagrams for various makes and models of cars.
I hope this helps! Let me know if you have any other questions.

91 olds 88 Royale misses, pops and lacks Power after Repairing code 41 and 13. New Magnet and new O2 sensor. now giving code 13 again. runs Horribly Rough.

Check for a vacuum leak. 13 is oxygen? If so, it may be a leak. If not, it may be a bad plug. Have you changed anything? Tried to get a code?

Ball joint, tie rod end or upper strut bearing. CV joints? Pulling to the left may be an alignment problem with front or rear tires. Get a four wheel alignment.
