Start with P0714 lean code which is likely an intake manifold (vacuum) leak. Could be you dislodged a vacuum line when putting out fire or a line was breeched. These can be notoriously difficult to find. Search "1999 ford explorer v8 vacuum leak" for help.
I found this on two 1999 F150 trucks with 5.4L. One was mine. There is a vacuum hose on the back passenger side of the engine that is about the size and length of your thumb. With age, this hose will collapse and then develop a vacuum leak. It can be pretty load if leaking.
It is a round cylinder that is bolted to the firewall/bulkhead and the brake master cylinder is mounted on it. The servo has a largish vacuum pipe going to it from the inlet manifold on the engine.

you have a vacuum leak probably the vacuum storage canister in the engine compartment.
