I’ve had my truck for over 10 years and have never had an issue. But in the last month has been running rough. To the point of almost stalling and shudders sometimes. Also noticed a whistle noise that’s new. Scanned it and they said EGR Valve bought a new one and changed it. Same issue no change...
