I have a ‘98 Chevy Tahoe LT with a 5.7 Vortec V8. I’m having an issue with my engine rattling pretty loud when accelerating under load. I took it to my shop and they said they’ve heard that same sound before with these vortec V8s and have never been able to solve the problem. My initial thought was that it was spark knock? Let me know if any of y’all have had the same issue and how it was solved.
