cel and car spitting at med rpm
i got a 01 a4 2.8 quattro manual.
got a cel P0173-fuel trim bank 2 condition. anybody got any suggestions? i just did plugs, put in bosch platinum +2. also the car is misfiring at about 4k rpm. i ran sum seafoam like 80 miles ago. didn't use as much as it said to, only used half the amount. no mods on the car. i do sorta feel a tiny bit of power loss and getting bout 300 miles/tank. i rly hope this cel and misfire is not very serious cuz already have to do the whole front control arms and rear pads and rotors.

RE: cell and car spitting at med rpm
MAF would be my first choice but running rich evoces the ECT sensor which is really the cold start choke on older cars but electronic which would make the system rich so overriding the ECT sensor ( coolant temp sensor )
