05 tahoe lt 4wd so about a month ago the tighten fuel cap message came across my message center. (No check engine light) fuel range was suffering bad it would go from 90 to empty on a 15 mile drive bad. went ahead and replaced cap with an ACDelco OE replacement same message. Did some research and then replaced the EVAP solenoid same issue. Did more research and replaced the EVAP canister and blew out all lines. ( canister was shot) fuel range is better but not 100 percent and tighten fuel cap message still comes on once a day or every other day. At this point I could use any help that I can get please and thank you
