thanks in advance guys.

 

move the ignition coil that's misfiring to another cylinder,to see if the misfire,follows that ignition coil,so you can rule out a bad coil.

 

I was gonna replace all the wires and spark anyways, when I do that ill try. My main thing is that speed sensor missing a tooth.

 

I almost forgot,take your A4 to a local Audi Stealership,our cars have a active recall on all the ignition coils in our engine,i had mine replaced free of charge about a month ago. ^_^

 

I have the v6 and when I called they said no recall on those igntions. Only recall i have on mine thats still open is the ignition switch which im getting repaired tomorrow.

 

anyone else ref the missing tooth
