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
change, etc.
Any suggestions would sure be appreciated.
Thx ! ! !

Plug wires are usually the culprit in the case you described.
Maybe one of your coils is cracked.

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 !
