Ford Explorer Missing and Idle Problems
i have a 95 4.0 expl. i bought it 3 yrs ago with an external water leak at the head gaskets at 95k so i changed the gaskets and a week and a half later it developed a miss or a stumble under a load. this started while on a cross crountry trip (tx to mich). Once i got to my destination it was -17 degrees and the check engine light would come on for 10 min then go out for 30 min, then quit once it got above 0. I figured something was freezing up. I changed the plug wires and the fuel filter it didn't help my problem. i then drove it back to tx and drove it like this for 2 more yrs, while changing parts when i can. I changed the idle air control valve and the plugs a second time in 20k miles with platnuim. I had thought it was the trans but a trans shop told me that it was in the motor not the trans. i changed the coil pack and just last week the fuel pump quit so i have changed that and the filter again. still the same prob, it has been 45k miles since this has been started and i am ready to pull my hair out. Has anyone had simular problems and how were they fixed???
Explorer 1997 V8. I replaced the plugs (motorcraftSP-432) and wire (Bosch Premium wire set) and now I have idle missing, MPG is 21 .any ideas
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
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.
"I have a 2003 Explorer sport and recently when the car idles the rpms pulse like someone is pumping the gas. the rpms only jump up about 500 and its seems like its getting worse. It pulses about twice a second. any ideas on how to fix it? "
That sounds similar to my issue
