1998 Audi A4 2.8L V6 Quattro Automatic 100k miles

My battery recently died so I replaced it.

I also replaced my spark plugs with Bosch spark plugs and OE wires but my Audi still vibrates on idle. What else could be causing this?

[drexplode]

injectors? or clogged fuel filter?

did you gap the plugs, even though they are new they might be incorrectly gapped or defective, any check engine light? plug wires on tight with electric grease on all terminals, clean air, fuel filter

[umoms]

the plugs are labeled do not gap. I had a CEL previously. It was a misfire but it seems to cleared it as i been driving a month without it. the air and fuel filters are fairly new also.

check your drivetrain mounts
