Had the starter replaced, now RPMs slightly jump?
2003 Chevy Silverado 4x4 5.3 V8 . I just had my starter replaced. Once I picked up the truck from the shop, waiting to pull out I noticed the RPMS were low and the needle was jumping a bit. The truck seemed to run a little more rough while idling. It never stalled but at one point acted like it was about to. I’m not the most knowledgeable with this issue and wanted to see if anyone had any thoughts as to what is causing this? Thanks!
