Stock 5.0L limited is hesitating at under acceleration, I noticed it a few days after changing the plugs and wires I installed taylor wires and NGK iridium plugs about 600 miles ago and about 200 miles ago I changed the fuel filter and yest put on a new TPS, IAC and cleaned the MAF. Still same problem. There is a rough idle once in a while when started but smooths out in seconds, and no CEL ever comes on. Also the EGR valve was replaced about 10,000 miles ago. so im lost with this thing. Im thinking maybe that DPFE sensor that has vacuum lines hooked to it. Any suggestions, guidance, opinions, gripes, or intuition please drop a line all is welcome. Thanks guys.
