ok guys,

I did my first spark plug, oil, oil filter and air filter change along with spray cleaning the maf sensor. The car seems to be running ok but for some reason i feel like i am not getting the exact same pick up i had prior to all this.

I don't want to say the pickup feels like a v6 but (maybe like a v7 - lol).
I cant check codes cause i don't have a vag com cable yet but i'm hoping their isn't any misfiring going on, or low compression due to under tightening.

my question is, can i just go in, unscrew,, and re-tighten the plugs, and see if that helps?

 

oh, when i say my "first", i mean my first do-it-myself job. And, it is a 00 A6 4.2 in case your wondering. thanks.

 

sure take them out and put them in just don't strip the holes!, I would check the terminal connections to your coils. Pinch the female pins so they fit tight and apply di-electric grease then re-plug them. I also dab a screwdriver tip worth of di-electric on the top of the spark plugs.

It's common for the coils to misfire after touching them because the terminals are not tight. Happened to me a couple times.

 

thanks, ill give it a try tomorrow. as of right now its at least driveable.

 

Take them out and put them back in 25 times if you want but (as said before) don't strip the threads. But check the terminals before you go to all the trouble.
