Misfire in #2 Cylinder and lost speedometer
I switched the coil from #1 to #2 and it still missfires on the #2 cylinder. I even went and bought a new ingition coil for the #2 cylinder and my car still shakes violently. I hooked up to scanner and it still says PO302 #2 cylinder still misfiring. Recently i chipped my 98 A4 1.8t and i am thinking that could be the cause of these problems. I also lost my speedometer reading. I also installed a new speed sensor and it still doesnt work. I NEED HELP!!!!!!!!!!!!

#1-quick compresson test
#2-move spark plugs between cylinders.
#3-check wiring to coil. 2 pins are grounds and one is power supply and the other is the trigger from the ecm.

i talked to a few pros today at the LA AUTO SHOW........
I was just at the L.A Auto Show and the APR guys were there who had their audis on display....i told them about my problems i was having and they had no idea what could be the exact problem. They said it doesnt just sound like one problem. Does anyone have any other thoughts as to what could be causing me these problems???
