The stock size in my S80 is 225/50/R17 but I'm in need of tires. I found a good deal on a set of 4 tires 225/45/R17, will this upset anything or affect anything in the cars system? Any lights? Warning?

OK so here is whats been going on. I decided to send my ECM to XeMODeX for a software transfer to a good ECM. Got it back and installed it tonight. Initially it ran well and then once the car warmed up it began to stumble, buck, and run rough again, and finally just shut off. It stumbles to the poin...

Dealer advised the ECU is malfunctioning and the car would require a new ECU.... Any thoughts??

Ok so we swapped the Rear Driverside O2 sensor and moved it over to the rear Passenger side slot. The car continues to miss, and now the driverside cat got red hot. So far no CEL or trouble codes...
