hey thanks for bringing me up to speed. ive been working on many other problems but with your great explanation i remember.
we need to check the compression on that cyl. and compare it to the compression on 2 other cylinders your choice.
but before you do this get a can of carb cleaner . and with the car idling spray around the intake manifold in the area of #6 cyl. what we are looking for is a small vacuum leak that would also act like this. with the engine idling and spraying around the intake the engines idle sould not change and if it does when you spray you have an intake leaking.
let me know how it turns out.
later
paul

SOURCE: Best way to remove rear 3 spark plugs 2000 buick

Most GM fwd v6s' have to be rolled forward to change the rear plugs. Its not as hard as it sounds though. Usually removing the air cleaner box and then taking the bolts out of the two top wish bone mounts allows you to roll the engine forward enough to change those plugs. You'll just need something to hold the engine forward while you change them. Like maybe a friend or a strap. I hope this helps you.

I need to know the drive cycle 4 the 98 lesabre


If you mean the firing order of the 3800 Series II V6 engine, it is 1-6-5-4-3-2. The numbers are usually stamped on the coil packs and care should be taken when running plug wires that the number on the coil pack lead goes the the corresponding cylinder number. Cylinder locations on the engine are as follows: Standing with the hood open on the passenger side of car facing the front of the engine (end where sertentine drive belt is located) The left bank is 2-4-6 front to rear, and the right bank is 1-3-5 front to rear of engine.

Anyone have a 1995 Buick lesabre custom, ignition wiring diagram?


Insofar as your Ignition Wiring Diagram, I hope you're speaking of what's also called the Spark Plug Cables or Firing Order. The proper Firing order for your V-6 is 1-5-3-6-2-4 with the number 1 cylinder being the front spark plug on the left hand side. The left hand side is Odd numbered and the Right hand side is Even numbered, therefore number 2 cylinder is the 1st plug on the right hand side of the engine.

Spark plug firing order


The firing order for this vehicle is 1-6-5-4-3-2. When you are standing at the front of the car looking under the hood, the plug in the left corner of the engine is firing in cylinder 1, as you move to the right you see cylinder 3 and 5. On the other side engine (the side facing the firewall) going left to right is 2 4 and 6. Remember, this is what you see standing in front of the car, not the engine. If you want to stand in front of the engine you will have to be standing at the passenger side fender!

Once you know this, it is easy to see the cross pattern in which the engine fires. Hope this helps you, cheers!
