Blue smoke but no lights on the problem


blue smoke on startup is generally from worn valve guides or bad stem seals on same (not really terrible as long as it stays the same) It will run rough for a minute 'till the oil in the cylinders is cleared out. Service engine light is pretty much on its own timer and does not mean anything but it's there to annoy you into going to the dealer. If O2 sensor was bad, it would eventually put the red check engine light on.

Light on dash states service engine soon


There is something wrong, they may not have had the correct equipment for your car. Even if they had the right scanner and it said nothing....means there is something wrong if the light is on. The computer doesn't put that light on for fun. I would try somewhere else, a lot of auto parts stores will check it for free.

1998 Buick Lesabre How do you test the coil packs?


the coils are one integrated block with 3 separate segments. the coil pack is mounted to the ignition module and can be unbolted from each other. one can test the coils from the underside of the coilpack with a dvom. having said that your car should still start if one paired coil fails, it would however miss on one or two cylinders. I would suggest to scan for codes, monitor live sensor data to see if you have a valid crank signal, check fuel pressure and spark voltage

99 buick Lesabre


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
