Explorer :: 2003 Ford Sport Trac XLT V6 4.0 - Hesitation / Jerking When Slightly Hitting Brake Constantly
Mar 1, 2012
2003 Ford Explorer Sport Trac XLT v6 4.0 with 89k.
Lately my truck has been acting funny. About 1 out of 3 times I start my truck and put it n reverse it starts doing what I would describe as a hesitation. If I sit for about 10 seconds, it will stop. But if I move while it is happening it will move and jerk as if i was slightly hitting the brake constantly (no the parking break is not on). It will continue when I throw it in drive until I give it some gas. From then on as far as I can tell there are no problems. It doesn't do it every time. I went in for an oil change and they told me I will need to replace the belt soon, so could that be the culprit?

We have a 03 Ford Explorer Sport Trac that we just changed the ICV on because after it would warm up it dies at intersections. Now it shutter quite a bit a dies in reverse. We took it to a transmission place and no codes come up.

I have a 2003 Sport Trac that basically died last night on me. I drove it 30 miles Shut it off for about 10 minutes came back out and it cranks but it will not start. I sprayed some starting fluid into the throttle body and it ran for a second, so it's definitely a fuel issue. I am just not sure if it could be a fuel pump, Relay, or a dirty Fuel filter (I have not changed in the 87K I had the truck). Because it ran fine before it died..

My Sport Trac will periodically fail to start after shutting it down for a short period. It doesn't stall, but won't start after parking for just a few minutes to a couple of hours. I've had it towed twice, but it always starts after it gets to the shop and the mechanic can't find a problem or a code. It has happened 4 times and seems to start again after it sits for 3 hours or more, definitely by the next morning. A fuel system cleaner had been tried and the fuel filter has been replaced, but the problem continues.

OK I replaced AC compressor a few months ago and everything was fine... Now today I put AC on and the AC is cold but only comes out defrost....
I do not hear anything trying to switch to front vents... Is there a fuse that could be blown....
Parts store guy said bad actuator.... have to pull dash..... but then said he heard of a way to sneak in the side of the center console....

I was driving my sport trac when it suddenly died on me. We are leaning toward the fuel pump. But is there any other causes for fuel to not get to the engine? We changed the fuel filter out already...

I have noticed a serious bump steer or a violent jerking action when hitting a bump in the road. Just over a year ago I replaced ball joints,tie rods, sway bar links (2nd set since cutting off original). I used MOOG components. I was shocked to see the sway bar links loose once again. Is there a certain way to tighten them or is there a better product available. Mostly stock 1999 'ploder with fire wires and scremin demon coil pack.

All other lights work including Driving lights and High Beams.
I have checked fuses.

About a month ago my Lumina (1999 LTZ 3.8L 85,000 miles) started jerking a little bit while slowing down almost like I was hitting the brake too hard and after 2 days of it the car would shut off while braking toward a stop sign or while idling and would to this without the jerk, no warning. I replaced the throttle position sensor hoping this would fix the problem, it did nothing. Soon after this the engine would jerk really bad while driving and shut off even during acceleration, the service engine soon light came on during this time. I took it to a local mechanic who said the error code was for a faulty mass air flow sensor, so that was replaced. This made things a lot better, no more dying or jerking while driving but there was a new problem.
When starting the engine cold no issues, when starting the engine warm after sitting 20-30 minutes it would shake and the RPMs would fluctuate by 300-400, but once I put it in drive and started going it would drive smooth. The service engine light came back on so I brought it back to the mechanic. This time they said the fuel pump wasn't pumping enough fuel (low pressure?) and it needed to be replaced so I did that but it created a new problem. When I would start the car cold the RPMs would jump way up to 2000 then down to 0 or it would jump to 2000 then down to 500 then up to 1500 then down and so on until I put it in drive.
So I brought it back again and they replaced a gasket around the fuel pump, put a new idle control sensor (i think?) and told me to turn the key to on, listen for the pump to stop pumping fuel and then start the car, I have never had to do that before all these problems. This worked fine for about 2 weeks and now I am back to the car shaking while starting it warm like it did before the new fuel pump and the service engine light just came back on. But again, once I start driving it runs nice and smooth like there are no problems.

I recently have been experiencing some trouble when initially starting my truck. It usually doesn't turn over on the first go, wait five seconds, cranks just fine. However when I start it the engine revs up and and down on its own sometimes, and when I put it into drive and reverse especially, I get a pretty good shake like the it's reving up and down. I pop it into neutral and give it a second and usually seems fine. My check engine light pops from time to time and I believe its some the solenoids triggering it. What is going on? I am not very truck savy at the moment.

At my wits end on this. Left front brake is pulling ever so slightly on my '02 RWD Sport Trac. Just enough to annoy the crap out of me. Sometimes I hardly notice it. Over the past year or so I've flushed and bled the lines after replacing rear wheel cylinders, rebuilt the front calipers and replaced the rotors and pads. It's still pulling. Is there some electronic adjustment for the module that the brake lines come out of? Does the ECM control the pressures?

I bought my wife a 2007 Ford sport trac about six months ago. It has always made a very peculiar sound. It only makes this noise when you are driving about 50 mph uphill. The sound is rhythmic and coming from the rear of the truck. I would compare it to driving over sets of rumble strips but quieter. The vehicle is 4x4 and my theory is that it has something to do with this.

My girlfriend just bought a 98 XLT AWD 4.0. does have a few problems.
First, the brake light is on (on the dash). all the lines are good, but the front pads need to be changed. if i take off hard, the brake light goes out for a bit.
Second, had a CEL. P0743, torque converter clutch circuit blah blah. also, the o/d light flashes constantly.
The trans shifts fine, even under WOT. also goes into o/d with no problems, and the button works.

Recently had my tire guy replace only my front tires on my 03 Ford Explorer. Drove it on the highway and it felt and sounded like the transmission and drive train were hitting each other. Having him now replace the rears as well. Hopefully, they will now be happy together. Fronts were new rears were worn and different tires. Will the new tires reset everything I screwed up?

I have an occasional issue when pressing the gas pedal while stopped or at low speed the car hesitates and slightly kicks. It doesn't seem to happen at high speeds. The auto mechanic I took it to said he is getting a read that it might be the thermostat. My temperature gauge has not moved above normal. The auto guy says they need to start with the thermostat and see where we are with the problem at hand afterward. This does not make sense to me. Maybe the electronic read is right and the thermostat needs replacing, but how can this affect my occasional hesitation problem?

Actually I know how Control Trac works in theory, but I mean in the real world. For example, when going through emissions we put it on the standard, rear wheel only rollers. If I understand it correctly, both driveshafts are always turning and if the system detects the back driveshaft going faster than the front it interprets this is as a loss of traction and can route up to 100%of the power to the front wheels. So how, when it was in auto 4X4 mode, was it able to go on the rear wheel only rollers? I am (assuming) that both driveshafts were turning at the same speed so the system didn't send any power to the front wheels. I know the 4X4 high and low work fine.

My 20th Ann. Is jerking under acceleration. When I hit the gas pedal slightly hard it starts jerking. Every once in a while the CEL will flash on and off. I changed the spark plugs and coil packs, cleaned the MAF, and now I have no real direction where to go. Maybe it could be a vaccum problem...

I recently had a problem with my car jerking slightly on highway, and I think I've resolved this by replacing the spark plugs. It does still do it, but maybe only one or two jerks per 100 miles. It used to be one or two jerks every 30 seconds. So I think I've found at least part of the source of the jerk. I could possibly purchase new spark plug caps (wires) and hopefully that would put that problem to rest.

So my car has white smoke coming from the exhaust. On start up, on warm up, on hot idle, and on cold idle. The coolant in the reservoir is quite skanky looking and I've been meaning to flush it but haven't gotten around to it. But I've done quite a lot of research lately and also just have my own personal experience (employed as a mechanic at a small engines shop for quite some time.) and I've found the most common answer would be a head gasket problem, or even more serious, a cracked block, causing coolant in small amounts to leak into the cylinders. I figured that would be the answer I would find but I like to do some research before I go prodding at my car.
The exhaust is white, not grey, not blue, not black. A nice pure white color, and obviously comes out thicker and in larger amounts when you give it some gas. Also it smells sweet. Another clue it could be coolant.
Another thing that made me worry was when I replaced the old spark plugs, they looked like they were being run in a really lean engine. Barely any carbon tracks on them, almost clean looking. Which worries me. It could be suggesting that I COULD be burning water (coolant) in my engine. The coolant level in the reservoir does go down but at a pretty small amount.

Only had this car for about a month and 1200 trouble free miles. Really in great shape but with 276K miles on it. Really runs great and feels like a new car inside and out.
Yesterday, a cool morning, 38 deg.. Started at the Ready, backing out of my car port and cut the wheel partially to turn 90 deg. to enter the street. Came to full stop and shift lever is still in Rev, before I could shift to Drive. The steering wheel shutters like I was going over a rough. Jerking slightly from left to right about 2-3 degrees. Stopped within about a second and I still had normal steering response. I continued onto the street and made a ran a 300 mile round trip on freeway and surface streets without any further problems.
I know the power steering is electric assist over mechanical linkage and can only imagine that there was a power glitch in the power convertor and I was feeling pulses from the feed back in the power steering drive. No hydraulics to blame, I don't think.

I have a 2009 Tiguan 2.0T Gas 2WD Tiptronic Auto.
I noticed a while back on a cold morning that at first start the idle would seem off a bit.
I only would notice it for about a couple of minutes and then it would smooth out as I began to drive.
Lately that still happens some but mainly I have some hesitation or slight jerking as I accelerate now.
Mainly it will do it while starting to take off slowly/ when pulling a hill/ and when having to maintain a low speed behind many other cars.
I can counter act it a bit by stepping harder on the gas pedal(when there's room) and getting the RPM to go and stay over 2000 like on the highway.
If it is under 2000 RPM you can notice it pretty well.
I am concerned as I have not had this problem before and it is very well maintained and cared for.
Though it is likely due for a tune up...
What could be the most likely cause? I don't really want to take it to the dealer first as they would want a fee beforehand just to check it out.
It had a check engine light on for just a minute one day but it did not stay on.
If it stayed on then I could get the parts store to check it using the OBDII scanner.

Santa Fe - 2004 - 2.7 liter automatic fwd.
I am experiencing an occasional jerking or hesitation while sitting stopped at lights and it also has a tendency to do the same as I begin to move from a stop at times. It almost seems like the transmission slipping or something but likely more engine related I think as I am at a stop. I have felt this slightly while at speed as well but not that often, at least not yet. It also seems more noticeable as the weather get warmer as was very noticeable late last summer and did not present itself again until spring.
Also-I have read that some threads re stalling issues(not exactly what I have) that can be related to the crankshaft position sensor and also read somewhere a while ago about an issue re the ecm needing reprogramming but have not found that recently.
