Thought I'd join the community. I've been surfing the site for direction to resolve a cold start stumble and backfire. Car's new to me, but adult owned well cared for 195k mile 5.0 hatch, AT.
Passed the problem off to a local shop that works on my other car, no luck yet. Runs fine after warm but rich.
Previous owner replaced exhaust including cats, new BBK 70 with cold air, MAF, shop tested and swapped out MAF, Coil, compression check, exhaust and collant sensor checked for vacuum leaks.... who know's what else at this point.
Lots of good advice here. Glad to be part of the community.
Whenever we get a bead on it, I'll share the outcome, seems to be a standard problem for 5.0's but a wild range of causes.
