Have a '96 LeSabre with the 3800. Under light acceleration (no downshift)
I can feel a 'jerking' from the engine. With a downshift and higher rpm
it is not noticeable. A computer check by the dealer shows no problems.
As an attempted fix, I replaced the sparkplugs and wires, no change.
Has 56k actual miles and displays no additional problems, leaks, mileage
Any suggestions would sure be appreciated.
Thx ! ! !
The plug wires were replaced by the dealer by OEM wires, so it is
unlikely they would be the problem....I think ? ?
Would it make any sense to purchase a single coil and to replace like the
old series xmas lites ? Plug it in, if no change, move it to the next, etc ?
Thanks for your insight !
I never promote part swapping, but if you have the $$$$ it's not unheard of.
I would remove the coils and ignition module and look closely for any signs of
carbon tracking, a telltale sign of trouble. You may also find a hairline crack
from visual inspection.
