Question about 1993 Buick LeSabre
What is the spark plug numbering diagram, front & rear left to right facing the engine?
153624 is possibly the firing order but the numbering of the cylinders ? never seen one so i wouldnt know sorry their out engines here in europe only use 4 cylinders and the newer ones 3 cylinders try 143625 if the first firing order doesnt work ,i would expect no 1 to the front left but i just dont know i could work it out with head under the bonnet and follow the rockers working out the timing but offhand no idea

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.

Ok this may be something smal that may be simple to fixs; your plugs are in the wrong cylinder?
Check Your gap size .060 (In thousandths of an inch)
Im not sure of the size of engine please look below for your make?

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.
