4.3L 2006 Silverado

Recently replaced ignition coil and it started running again but the issue that it’s still giving me and was giving before replacing that part was having to give it some gas and holding it for awhile when turning it on so that it wouldn’t bog down and shut off. It’s been 2 weeks since I replaced the part and today it shut off on me while driving and I had to give it gas to get it going again to get it home. Any idea what it could be.

Welcome to the Forum! First thing to check with any diagnosis is for any codes . If you do not have a code reader go to your local parts store and have them check it. Then post the codes WITH their definitions here and then we can offer constructive advice. There are over 18000 possible codes ,no one remembers them all so definitions are a must
