Figured I'd ask as it popped into my head just now. My F150 takes, in my opinion, a while to come back down to idle if I give it gas (say, to 3k) while sitting in neutral/park. Perhaps saying "it takes its time" would be more appropriate. It could be perfectly normal, but I figured I'd check. Granted, my frames of reference aren't other trucks, but an 06 Impala SS, an 09 Challenger R/T, and an 06 + 11 2.4 VTEC... so maybe I'm just crazy. lol
