Been having some problems with my 2007 Volvo S60 (2.5T) Stalled a few times at low speeds, slow acceleration, Rpm drops.Check engine light has been coming and going but i recently had a light that said ENGINE SYSTEM SERVICE URGENT, so i got the codes scanned and the codes are: P0193 - Fuel Rail Pressure Sensor High
P0088 - Fuel Rail/System Pressure - Too High
P0190 - Fuel Rail Pressure Sensor
Any suggestions on what to try first?

 

Welcome to the forum

 

first thing to do is get a full scan done with a proper tool that can read the pump input - unless you'd rather play parts roulette. If so, you can try replacing the fuel pressure sensor first - there's some vids on Youtube that can show you where and explain some of the common symptoms. After that it gets more involved - ie fuel pump, controller etc.
