#17 of 27 ford explorer 5.0 AWD misses under load by bbelasco

Jun 04, 2009 (6:03 am)

Under load the car pops and misses, idles fine, also revs fine. I have checked vacuum of intake manifold, checks out just fine. Removed exhaust system, no restrictions, still pops and misses under load. New spark plugs, does anyone have any suggestions as to where to look. Check engine light is not on, no codes.
 
Thanks

good luck with that i have the same problem with my 95 4.0 for the last yrs and 50,000 miles. i took it to a dealer thinking if anyone could find it they would....they couldnt i changed the iac valve and the tp sensor the coil pack and the plugs and wires twice all the vacuum lines and even injector o-rings...nothing helped. they wanted 300 just to pull the plugs because they couldnt find anything else. I am leaning towards possible timing chain or failing lifter. One person told me maybe the pcm. i still dont know but it still keeps chugging along

#19 of 27 2002 Explorer V8 , losing HP, knocking and running very rough by deetee

Jul 04, 2009 (1:06 pm)

Hi Guys,
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 27 99 Ford Explorer performance issues by grabula

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.
 
Jason

That sounds similar to my issue

#23 of 27 Variable idle speed '99 Explorer by slickster

Feb 03, 2010 (5:28 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.
 
Thanks, guys!
