#19 of 28 2002 Explorer V8 , losing HP, knocking and running very rough
Jul 04, 2009 (12:06 pm)
My explorer, is running rough and losing horse power. When I go to excelerate it just lugs, 2500 RPM's and going 30 MPH. IT is knocking like hell as well, it sounds like the engine is very over heatedor running out of gas but its not , coolent is full and gauge is mid point. I have always had the car serviced when needed. I have never had this issue before. Could this be a fuel injector or fuel filter issue and is there a way to check. I am hoping it is something this simple. Could a manifold gasket cause the same symptoms. Any help would be greatly appreciated. Thanks

#22 of 28 99 Ford Explorer performance issues

Engine Performance problem
1999 Ford Explorer 6 cyl Four Wheel Drive Automatic 149000 miles
I've taken my vehicle to a mechanic 3 seperate times and he has no idea what the issue is. He says he can't duplicate it but for me it happens just about everytime I drive it. Here is the breakdown I gave him:
- When maintaining speeds of 35mph and 55mph, RPM's drop down from 2000-2500 to below 2000 and I can't get any pickup or gain any speed. I can take my foot off the gas and then press it again and sometimes that fixes the issue.
- When this happens I can maintain speed but cannot accelerate.
- Occasionally while idling the RPM's drop down repeatedly. It idles at around 1100-1200 normally, but drops down to about 500-800 repeatedly about every few seconds.
- Occasionally while driving at high speeds 55+ there is a loud "clunk". This is typically when roads are in a bad condition. We have confirmed 4 wheel drive is not working and I suspect this may be related.
I bought the truck in August and since then it's gradually got worse. It seems to occur more frequently when the engine has warmed up a little.
Thanks for you help in advance.

That sounds similar to my issue
#23 of 28 Variable idle speed '99 Explorer
Feb 03, 2010 (4:28 pm)
Automatic AWD 4.0 V-6. Drove the same engine 240,000 miles in a '92 Ranger. Bought the Explorer [110k] last summer & love it EXCEPT: when idling in Park, swings between 800 and 1200 rpm without touching the gas? When idling in drive [stop light, etc.], stays about 800. Sounds like something simple, I hope? The mileage is less than I expected and this is probably part of it.

#26 of 28 2001 sport won't start even with ether
Nov 20, 2012 (7:08 pm)
I have spark. She cranks. Iac valve not stuck shut but open about 1/2 inch. Haven't checked codes. Need to get it to a code reader. With ether it almost wants to start. I have reset the computer twice with disconnecting the battery 30 minutes each time. Maybe didn't reset it right? I checked for spark and it got that.

last week the motor developed a random issue, the check engine light came on it was a 0300 code which is a random missfire, everytime you start it it has a very rough idle almost like its fighting itself, i cleared the code changed plugs wires coil pack exhaust everything i could think of and it still hasnt helped. The check engine light hasnt come on again and if it was something electronic you would think it should, i have had several mechanics look at it also and they said it could be fuel injectors, or the computer, ive tried to check the injectors but the intake is in the way and im not sure where the computer is located, Also ive been told you can get the computer tested?
