Coil packs? I had a similar problem a while back and it was a bad coil pack.
Okay so i just bought an Audi A6 Quattro 2.8l and it has some issues.
it has 87k on it and its a 99. its been taken care of timing belt was done at 80k oil changed every 3k and paperwork to prove it.
PO was dirving it and all of a sudden it started sputtering and bucking, he was 10 miles from home so he just drove it and parked it and then i bought.
the car starts and rev's to about 2k rpm and then bogs down.
EDIT: so i took my spark plugs out to test compression and this is what i found... they were covered in oil? it was on the wrench too so i think its a valve cover gasket leak. its on both cylinders 1 and 4 i havent checked any others. what do you guys think? could it be valve seals?
here is the most recent scan

so i think i need a coil pack and maybe a throttle body?
i dont know about the throttle body though i thought i would just need to do a TBA but when i went to do it, it said error. maybe thats cuz of the misfire.
anyone's input would be great. thanks.
oh and pics
i just purchased a used coil pack from the classifieds and a new valve cover gasket from ECS.
i will keep this updated and let you know if it fixes the problem.
i bought this car for 900$ i should make out pretty good on this one.
