I replaced the mass flow Sen and it still comes back the second you turn on the key. Please Help. Double J Veteran / Moderator Apr 25, 2008, 6:53 PM Post #2 of 4 (1804 views) Re: 1999 Express 3500 5.7 Sign In Did you clear the code from memory after replacement of the MAF? If not,clear the code...then test drive it and see if it returns. If so,suggest looking closely at the MAF wiring/connector for any broken/frayed wires. Also look for any air leaks at/near the MAF.. Just some suggestions Let us know Jim GH3 New User Apr 26, 2008, 4:47 AM Post #3 of 4 (1800 views) Re: 1999 Express 3500 5.7 Sign In Yep I did that.
