I have a 2002 for explorer 4wd 4.0 it won't accelerate. it's fine to 25, but it pings, and won't go over 40. I've changed to the plugs, wires, coil pack and fuel filter. I've also checked the fuel pressure, and it's 65psi. no codes are being set. I've been told plugged cat, but they're welded on, and no way to test them...
View 1 RepliesI have a 2002 explorer 2wd. I am trying to find an answer for this thumping noise as I accelerate. My first thought was a tire. I took them to be checked and had one replaced but all are good and less than 5k miles on them. I feel it in the pedals and in the steering wheel. The repetitive sound increasing with speed. I have, in the last 2 weeks, changed front rotors and pads with no difference in sound but good brakes now. And today replaced the drivers side upper ball joint and the front ds wheel hub assy. And no difference. What may be the problem?
View 1 RepliesIn the last month or so I'very had trouble with my 2002 Explorer having trouble accelerating. When I take off from a light it hesitates badly. It feels like it's got air in the tank. It does it every time I need to accelerate, including coming around turns. I'very put in fuel injector cleaner and it works fine for a little while, but then has the same issue. Yesterday morning it wouldn't turn over in the morning. I changed out the battery, but I had a similar issue of not turning over. It eventually did. I was wondering if the two might be related. Could it be a fuel pump or fuel pump relay?
View 1 RepliesI have a 2007 150 5.4 31,000 miles that started knocking and pinging at low rpm, fine above 1000 rpm but i am detecting ackward exhaust tone, after reading several posts on this site about similar complaints i replaced the cam sensors but prob persists.
View 1 RepliesIt's a 2004 4wd 4.6 v8 with 140,000 miles. My wife was driving around town today and had to park it at her daughter's house because even if you floor it,the engine will only rev to about 1500-1800 rpm's and idles really low,maybe 600 rpm. she said right before it started running bad,there was a bad smell. Also there is a humming/rattling noise that sounds like it's coming from the upper intake/throttle body area. I went and looked at it,tried to pull codes.
The check engine light isn't on and there are no codes stored in the computer. A couple of days ago,there was code po420 (Catalyst System Efficiency Below Threshold (Bank 1)and the check engine light was on. Engine was running fine. I cleared the code,and it never came back. I am not sure this is related,just trying to give all info possible.
I have a 2000 Ford Explorer XLT. V6, 4x4
At very low speeds (5-10 mph), attempting to accelerate while turning (like coming out of a parking lot OR out of a curve) the transmission fails to engage. I hit the gas, the RPMs go up, but it doesn't get into gear. I will let off the gas, give it a couple seconds, hit the gas again and usually it engages. Sometimes I will have to repeat this step a second time. This problem started very slowly and has gradually gotten worse. It happens about once a day.
Concerned, I took it to the local Ford dealership and they have thus far changed/flushed the transmission fluid and replaced the filter. The mechanic said he found no metal shavings in the fluid, which might indicate grinding gears. They also said there were no codes coming up pointing to a transmission problem. It is still having the same exact issue however. The trouble now is they cannot "verify" the problem. The mechanics have put 40+ miles on it in similar driving scenarios and it will not act up for them.
After a couple weeks of back-and-forth, I'm really frustrated. My understanding is that they're "not sure" it is a transmission problem. They don't really want to open up the transmission case until they have a place to start. It should either be something mechanical with the transmission or a problem with the computer that controls the transmission, right? After getting off the phone with the mechanic today he said it might be a sticky throttle body?
My sport trac has just started having a very strange problem. When I start the truck none of the gauges on the dashboard work... not the indicators or the RPM or the speedometer. The gas gauge will visibly move higher when I brake and lower when I accelerate.
But a few min after I start driving everything pops on. What could be causing this?
2 wks ago I was running down I95 at about 95-100 mph (basically floored) in a rush to get somewhere on time. Since then my truck has been running for crap. It threw the p0171 code when I checked it. When driving under normal conditions it pings a lot and my mpg is down about 3 mpg and has this hesitation when you get on it. Even when you accelerate at a normal rate it surges a little, it pings a lot and has a loss of power, about 30-40%. It feels really sluggish and doesnt want to pull and then you will feel it starting to pull a little harder then it starts to surge/hesitate a little again.
Truck has 147k on it. I was having a similar situation until I had the plugs replaced at 125k, so I figured the plugs shouldn't be the problem. So I replaced the fuel and air filters, cleaned the maf w/maf cleaner and Throttle body w/tb cleaner and replaced the pcv with a new one from ford. Still pings bad under load and still has the hesitation/surging and crappy fuel economy. Its running smoother but no fix yet. This is crazy trying to pinpoint this issue. The detonating isnt crappy gas because I used super and it still detonates quite a bit.

My 2008 jeep wrangler x 6 cyl pings upon acceleration. 62000 miles.
View 6 RepliesI have a 2009 x5. 29k miles. The car pings going up a hill in sixth gear. I know sixth is not strong enough, I downshift to fifth gear and it does not ping. The car has a three liter engine. In the past, other cars would just wait for me to downshift automatically or manually using the steptronic transmission. Is the timing off? Or is this normal?
View 10 RepliesI test-drove a 1994 Honda Accord with 140K today. Looking for reliable car for relative, and this was one of the better options, on paper at least, in the price range.It drove like a used car, but I was concerned about one thing: A ping when accelerating from low speed. It didn't do it constantly, but only when going from a standstill or slowdown back up to speed. The seller said he'd been told it was an issue with the catalytic converter. I've been told that a higher octane fuel will sometimes quell a ping in an engine with no knock sensor.Is this something I should be worried about? Is the high-octane rumor true? The car was otherwise very nicely maintained.
View 1 RepliesI've noticed this more on the Phaeton than the last two cars I have owned. When the car is warm and I arrive at my destination and turn the engine off, the engine makes a lot of little pings and pangs for several minutes. Don't know how better to describe the sound. Does this mean anything? Normal?
View 6 RepliesThe engine "pings" shortly after I get in and drive it when the car is warming up. I watch the engine temp rise...and when it starts to get warm just before the thermostat opens and the temp drops the car "ping or pre-detonate" when the accelerator is gently pressed. After the engine warms up... no problems. I drove it from Port Angeles Wa to southern Oregon with out it ever happening... but when I drive a short distance to town it consistently happens. I have checked what I know how to but beyond that it seems odd. Its it normal for the engine temp to rise up warmer than the normal operating temp, and then drop back down? The thermostat was recently replaced. It seems something is creating excess vacuumduring the warmup time that makes the engine ping. All the vacuum gizmos and gadgets make me crazy...
View 1 RepliesMy brother has an 02 ford escape that he bought cheap because it needed a transmission. He just replaced the transmission in it as well as tie rod ends, front axles, axle bushings and seals. The front pads and rotors are new and the tires were just rotated. Now when you are going 15mph and up and are on the accelerator there is a severe shaking as you accelerate and a loud thumping noise. If you let off the accelerator it goes away. If you get it going fast enough it will shake so bad the mirrors will shake. He is a ford mechanic but said he is having a hard time pin pointing what it could be . He took me for a ride. He said he has had other mechanics look at it but they can't figure it out.
View 5 RepliesI am having a lot of issues with my 2002 ford escape, a while if I drive the truck acts normal, but after driving it starts missing when beginning to accelerate at a dead stop check engine light starts flashing pulled codes coming up with #4 cylinder misfire and #5 cylinder misfire detected, also a catalyst system below threshold bank 2, I have had the vacuum lines repaired and still no changes and went through and changed my grade of fuel from regular unleaded fuel to premium fuel, actually went worse with using premium fuel. I was thinking of replacing all three coil on the front of the motor, putting new plugs in it and seeing what that does.
View 2 RepliesAfter using the 4wd it's not going back into 2wd,the 4wd lo light is on and I dont hear the "click" when turning the switch. I've had the truck several years so I know how the 4wd works,is there a fuse or something else to try?
View 4 RepliesI just bought an 02 explorer it has a 4.6 V8 it has a bad motor. I was wondering what other vehicles and years I could take the motor out of.
View 2 RepliesI recently acquired an 02 explorer sport. Noticing a loud hum(similar to what knobby tires sound like) at 25-40 mph. Doesn't make noise at any other speeds. I replaced both front hubs, new shocks, new rotors and pads, sway bar links, even tried rotating tires, absolutely no change. Tires are a standard highway pattern , not luggy so I don't think it's those. Kinda lost on what to do next.
View 9 Replies2002 explorer 4.0l. No crank just click new starter in and cables hooked to battery...
View 1 RepliesThe 4x4 lights do not come on. I have check all fuses. I have replaced my module still nothing. I guess I could try another module but dam I am really at a dead end before I have to take it to Ford dealer and get hosed.
View 2 RepliesKids called and said the battery was dead, truck would not crank over. 2002 EXP 4 L. Drove 90 miles and checked battery to be o.k. Changed out with my truck to double test... no crank. Decided the starter must be bad. Banged on it with a long pipe from above - no start.
Winched onto a trailer and brought it 90 miles home. Winched it off and pulled to the garage. Looking from above i looks like this is a straight forward solenoid / starter / hot wire to the battery. No switches/ etc in between. Though i would try it one more time ... clicked key on and off 3 times and truck started on the 4th turn.
Tried it 6 times over 2 minutes and it started every time.. I am thinking the starter and solenoid don't owe me much after 11 years and 165k miles. Plan to check the cable and ends also.... Just wondering an specific known problem with the starter / cables before i jump in.
