02 3.8 hesitates when throttle is past one third to WOT. Runs smooth with light throttle up to about one third open. No codes. Car has 109,000 miles.
I have recently replaced: plugs, wires, fuel filter, DPFE, EGR solenoid, right after-cat O2 sensor, cleaned MAF & air filter and replaced EGR valve about one year ago. I have recently tested with another EGR that I know is good with no improvement. O2 sensor was a guess, so don't want to guess anymore.
Engine idles fine, will smoothly acclerate with light throttle. Will miss in any gear and neutral, greater than about one third throttle.
I have looked at some of previous posts but did not see same problem, some similar but not same.
I would appreciate any help or direction to previous applicable posts.
Thanks in advance.
