Hey Guys,
I'm still having some problems in 93 octane mode of my APR chip. Stock mode works great. 93 octane mode mis-fires like crazy when accelerating hard and I get Flashing check engine light. I just had the Audi dealer replace the spark plugs and one bad coil pack.. and they claimed it was good to go after charging me $350.. Of course this didn't help:banghead: . So, I called APR and asked for some advice. They said check to make sure the plugs are gapped properly and I should have all the coil packs replaced. Well I don't wanna have the dealer charge me another $350+, so is this something I can do by myself? is it difficult?
Thanks,
Steve

Recheck the plugs. Event though they are "specialists", I would double check that they used the right plugs for you engine. I had similar sounding problem after spark plugs were changed. I was going nuts: the car would drive OK if you don't push it and then start misfiring like crazy once you try to accelerate harder. All it took was putting in the right plugs.

I think the stock plugs were ngk's. I would have to second with sasha. The coil packs could be a little pricey. What kind of plugs did they put in at the stealership?

i recently had a coil pack fixed and it helped a bit with the sluggish issues but im going to have the other 3 changed. My indy charged me 50 for changing 1 coil pack and another 50 for spark plugs and install. total of 100 dollars. You def. need to find an indy. Im also going to have my fuel filter changed. I found that the car seems to run better in tip then in automatic mode.

don't ever use Bosch plugs on our cars.

Also if you have access to VAG-com you can easly find outif you need new plugs or coil pack.
If the vag-com diagnoses cyl1 misfire, swap colipack with other cylinder and see if the problem follows the coilpack. if not it is the spark plug.

to change the spark plugs on hte 02...

Take off engine cover
Pull off the connection to the coil pack.
Pull upwards to remove coil pack (mine took a good amount of force)
use a spark plug socket + rachet extendor to remove spark plug (make sure the cylinder is clean of debris)
Prep new spark plug (dieletric grease, anti seize)
Screw in the new spark plug by hand using the sparkplug socket/extendor
Tighten to 267 inches/lbs

I believe these are right
