What do these DTC codes mean??
On the climate screen following the usual Recirc up arrow - 1c displayed the following:
Codes came back as follows: 183, 221, 53, 87 (would any of these be responisble for the missing I get around 2500revs?)
Looked them up, but not sure if I found the correct definitions

Fuel temperature sender-G81 Interruption/Short to B+
Throttle Pos. Sensor -B- Circuit Range/Performance
53 & 87 I cant find
