Recently my explorer has been having fuel issues. It has a rough start which happens after sitting for at least 15 minutes. Every now and then, it will fire right up. When going up hills, the motor gets really loud and it feels like it has no power. It will drive fine, but when you slow down to a complete stop, the idle will get down to around 400-500 rpms and start to mildly shake. It will take off perfectly, but the motor gets loud when accelerating. It is currently sitting at 229000 miles, and it has a 4.0 V6 OHV motor.
What we have tried
Fuel Filter at 221000 miles
Recent Injection cleaning
Platimum spark plugs at 215000 miles
However, it does have the original fuel pump and fuel pressure regulator at 229000 miles. There is also no check engine light on, and no codes in the system.
