Chosen Solution

2000 Ford Expedition (Eddie Bauer edition) Triton V8 My truck wouldn’t start so I replaced the battery, no luck. Towed to shop and had the fuel pump replaced. Ever since I got it back it feels like its missing something. Rpms are sometimes going wonky (up and down while at a red light). The engine light isn’t coming on, but I know my truck and it isn’t running the way I know it’s supposed to.

I’d take it to an AutoZone and get a free computer diagnostic so you know where to look for a fix.
