Sudden rough idle multiple codes
 

Hello-

I'm new to the forum and seems to be some knowledge here! I've search the forums but I couldn't find any information on this situation.

I recently bought a 2006 XC90 V8 AWD and the say I registered it I stopped at a stop sign and the engine went nuts. Extremely rough idle, acceleration was smooth enough but you could tell it wasn't full power.

Scanned the codes and got all the misfire codes (P0300-P0308) plus P0106 P0171 and P0174.

Both banks leaning out suddenly tells me it is a fuel or sensor reading improparly.

Before I throw parts in it, (MAP Sensor and so on) I was hoping someone could give me a little insight on a similar situation.

Thanks in advance!
Nick
