Question
What is the firing order of the spark plugs on a 1991 6 cyl. Buick Park Avenue.
Antoinette,
Please let me preface this: I'm a Parts Professional, NOT a Tech but I will give it my best shot.
It looks like the firing order for your Buick is 1 6 5 4 3 2. It should be on the intake manifold. This is for a 3.8 liter, 231 with a vin code "L". (The 8th digit in the vin which can be seen through the windshield on the driver's side).
If you go to almost any Public Library, they have a Reference Section. You can find this information there in the Automotive Section. You can't check out the books but you can photocopy the pages you need to help you repair your vehicle.
I hope this helps. Good luck and welcome to Spring!!!!

Heretofore, I will NOT answer any mechanical question. I am not qualified and can only offer speculations. You are better served by others that are true Techs. With that being said, please only ask about parts and locating obsolete Auto Parts. Thank you. I have the ability to locate quite a few mechanical parts for American made vehicles fron the 1900`s to present. Some are OEM and some are aftermarket. This would include engine, brake and chassis parts. Body parts and trim are VERY difficult to find but you may inquire. If you need assistance in repair, I have illustrated books for major American manufacturers that show some illustrations BEFORE 1974. If needed, I can supply repair manuals for your specific vehicle. PLEASE REMEBER I'M A PARTS SPECIALIST, NOT A TECH!! Thank you.. Skip
