Ford ExplorerThis long running SUV has stood tough against the barrage of new entries into the mid sized SUV market, and with a variety of engine sizes and trim lines, the Exploder offers something for everyone.
I have an 03 Explorer with the 4.6 2v and have tried everything I could possibly think, find, or fathom. Its hard to also find a competent mechanic thats willing to take the time to look at a 20 year old vehicle. This has also been putting a damper on the marital affairs as this is my tow vehicle and I have less than a week to fix a problem I've been fighting for 9 months before we miss a camping trip.
Lean condition for both banks. I smoke tested the intake manifold through vac lines and also the egr tube. No leaks at all at the moment after fixing a bunch, other than a small one from the throttle shaft linkage side, which I've been told is normal. My short and long trims combined are 25-35% both banks at idle and will stay that way while driving. Long term pegged at 25% will come down a little bit while driving but never really below 18%. I use forscan and have clear adaptations millions of times and after each attempted repair. couple shops Ive brought it to say fuel pressure is good and I believe it. This thing is dumping gas, display says 9 MPG. It's also running like crap, full throttle is less responsive than 75%.
Things I've replaced Oem plugs oem coils Ngk MAF sensor Ngk Upstream o2 both Ngk Tps egr valve Remanned oem injectors Throttle body gasket Felpro Intake manifold gasket dorman intake manifold after thinking it could be cracked manifold
oem fuel filter
fuel damper(regulator) There may be more that I've missed.
I'm at a loss of what to do, I need help please!!!
