Ford - Mustang :: Losing Power When Braking
Jan 31, 2013
Sometimes when I brake to come to a stop, my car loses power: the whole thing shudders, RPMs take a dive. It doesn't start immediately on braking. It starts when I am almost at a stop, but not at a full stop. If it's relevant, I generally brake quite gradually, starting several car lengths away. So there are several seconds between onset of braking and onset of power loss. It starts while the brake is depressed. It does not stop when I let up on the brake. It does stop when I depress the accelerator. If I am idling at a light, it might happen. If I am just going slow without braking, it doesn't happen. Braking is fine in all circumstances except coming to a full stop.
Details:'93 Mustang, 4-cyl, 2.3L, manual, fuel-injected
It's been doing this for years, actually, and yes, I've been just dealing with it instead of getting it checked out. Usually a little rev of the engine gets her through it. Last night, it actually stalled, several times in fact. It restarted, but it did take cranking it for a while for it to restart.
Now that I think about it, my battery might be up for replacement. It's probably around 7 years old, and the last 6 have been very light driving, maybe 3k per year. But like I said, this is an ongoing problem. What should I be thinking about besides the battery, and what is a mechanic likely to tell me?

My 1990 mustang 5.0 LX has a very consistent stalling problem when travelling long distance on the highway at a good speed. After 2 hours of driving highway speeds and then pulling off the highway, the car stalls after I brake or stop at a light. I don't know why this seems braking related, but not sure. I then sit and crank the motor and it cranks for a bit and starts right up. I think it's fuel, but now sure yet.
Here's what I have done:1. Tune-up: plugs, wires, cap, rotor2. new fuel pressure regulator3. new fuel filter4. new fuel cap5. Checked for vacuum leaks (none found)
It seems to not happen when the gas tank is low, but I can't swear to it.
I'm going to run a fuel pressure gauge to the futhel rail and see if I can catch the drop off of fuel pressure when it occurs. Also, I noticed that the gas cap does not hiss when I unscrew it at any point in time.

Ive noticed while driving my 2k7 XLE 3.5L that when I brake moderately it is a very smooth transition until it lets up a little bit which gives me the feeling of losing control slightly. It is really weird to me that feeling of it "letting go" after it already was braking smoothly. When I brake hard it does NOT do that, which I find odd... Is it a normal occurrence for this particular ABS to act like that?

It did this funny thing about 4-5 times over a span of about 24 hrs before dying and then won't start. It was like hitting the limit on a speed governed car.....sudden momentary loss of power..and it seemed to be when accelerating if that matters. The thing I'm sure of at this point is that the fuel pump is not coming on when the key is turned, I know that sound well, but also checked it at the external connector with a test light for thoroughness. I also found a blown fuse under the hood which coincided with a little smokey smell inside the car when the fuse was replaced and blew again.
There is no spark as well. My Haynes book says that the PCM is behind the passenger kick panel but I only see the eecv and it doesn't smell burnt. The IFS is good. There is power at the coil packs. Fuel pump relay fuse is good. Is it more likely the ccrm since it contains the fuel pump relay and PCM relay or could it still be the eecv? It feels like one part failed but is causing more than one "problem", no power to fuel pump and no spark.

Our escape recently started loosing its power steering, once the engine is shut off the power steering is ok. Also some times you can feel a pulsing in the steering wheel. I've been doing some googling and it looks like the dealers are replacing the steering columns to fix the problem.
My question : is this the only fix or if something like some contacts being cleaned or maybe replacing a steering sensor of some kind is the fix.

I have a 1999 7.3 with 260k miles. It is all stock with the exception of straight pipe. I got the truck about 8 months ago and have put about 5k miles on it. Have never had any issues with it. I was driving from Dallas to Houston and about 45 minutes into the trip my truck lost power. I was going about 65-70 mph and the service engine line came on and I lost power. It was running rough and was blowing white smoke. I let it sit for a couple minutes and started it back up and ran fine until 30 minutes later. It did this 2 more times on the way to Houston. Oil is good, coolant is good. Not over heating. Threw a code the first time but didn't throw it the other times. I brought it to a mechanic and he thinks it's the Wastegate.

Where I should start? My 7.3 is running but losing all power. Pumping the fuel pedle will get it started and it will run for a few then lose everything again. Should i just drop the tank and check the sending unit and intake and filters first then work my way up?

2003 crank no start, 196k bone stock truck egr still in truck and stock head bolts. Replaced the icp sensor and ipr sensor, both from ford. What happened is I got fuel then about 15 minutes afterwards my truck acted like it was going up a hill and was just losing power and shut itself off. ficm tested 48.5 volts all 8 injectors tested good and there is oil pressure. Had an egr fault code but I'm at a loss.....

I have a 04 F30 4x4 with a sick 6.0 power stroke. It has 230k on the mileage and ran good. I was driving at speed when she started missing like it had lost an injector and loosing power. The RPM's dropped under 1000 so I had to pull over off the highway. When i pulled over and put it in park it shutoff. Tried several times to get to start but after 10 minutes it started up. I drove about 2 miles and it started the same process. This went on 2 more times before I was able to finally limp home the 40 miles.
It never shut off again but ran very poorly. I put a new valve in and when I tried to start it just mad a pound clunking/clacking noise. The repair shop put a starter in it because it had stopped engaging and was going to ruin the fly wheel. I looked at it and it was eaten up pretty bad from trying to get the engine to turn over. So now all it will do is a single clunk and will not turn over. He says it could be a bad injector that flooded a cylinder or blown up in the bottom end. He did take serpentine off and still no go.

this morning I started my 2004 f250 drove a mile and filled up my truck. Then drove another mile and my truck acted like it was running out of fuel. It was loosing power then stalled out and wouldn't start. About five hours later I tried to start it again and nothing. about five hours after that I tried it again and it started up and drove fine.
My thought was fuel filter or the water trap. I haven't had a chance to open the filters up and check them yet. Today while I was at work I got on here to see if I could figure out what was wrong with it. all I could think of was maybe the HPOP went out or the ICP sensor. Could one of these be the problem or was I right with my original thinking and it's just a fuel filter? First thing in the morning I'm going to pull the filters and replace them.
Could there be something else wrong with my truck that I don't know about? Like I said I filled up the fuel tank then it lost power within a mile and stalled out and wouldn't start back up. Then about 10 hours later it fires up and acts like nothing happened.

2004 f450 with 6.0. Was driving down the road when it started losing power like it was starving for fuel. It carried on for about a mile then died and will not start. No codes at all and we put a new fuel pump on but still wont start. Put a rag with gas in the air box and will run but rough.

I have a 2006 f250 6.0. the truck has 101k miles and to this point I have had zero issues. I am having trouble loosing power after running at highway speeds. Once I stop and begin to accelerate the truck looses power for a few seconds ,Belches smoke and begins to operate normally. I had an egr code, so I replaced egr and the problem persist. It is intermittent and does not happen if I stay under 50 mph.

2011 F350 diesel with 10,000 miles. I have been experiencing problems with the truck loosing power, making rough running noise (pinging like an older diesel), and vibrating. As though the motor is bogging down. It usually occurs on small inclines or hills with the truck in higher gears and low rpms. It will also occur running on flat ground 65-70 mph. Had it occur once while turning the truck around in 1st gear and low rpms. Depressing the accelerator will bring the truck out of it.
This problem occurs randomly sometimes a couple of times a week to not at all. Took to dealer and they found no codes and of couse it didn't do it on the hour long test drive I took the mechanic on. However they did say they had two other owners come in with the same complaints, but could not get trucks to repeat the issue. Problem usually occurs in the hotter part of the day, maybe just coincidence. I had seen similar posts with this problem but no conclusions.

2011 6.7 with 3.55 gearing. Just got the truck. And it seems when its cold the truck will rev high in 3rd gear and then sort of fall into 4th gear sort of losing power for a split second. If I gas it hard, its not as bad. Usually only happens like I said when its cold. Check the trans fluid its full and looks clean. My guess is some sort of sensor or the computer???

Truck started losing power then service engine light came on, drove about another mile then it just stalled ( almost home lees than a 1/4 mile). Got out open hood oil everywhere on top of motor. Looked under truck and oil all over the road. Looked back where I was driving a line of oil as far an I could see. Checked oil barely any on stick. Where should I start hpop or plug?

I have a 7.3 Excursion, 234K Miles, 4R100 Transmission. Today I was in a rush to take one of our dogs to the vet, when I hit overdrive going up a hill, it almost sounded like a clicking noise and I was steadily losing power. I came to a stop sign and put it in park and it started to develop a constant lope that was rough. Whenever I would step on the gas it would put out white smoke which it has never done before. I was able to take it a couple miles before it did the same thing except this time it shut itself off.
Recently I have been having transmission issues as it feels im losing first gear. A while back I noticed it would idle slightly in park every now and then. A couple days before this happened, I came to a stop and my truck started loping slightly and first gear IN DRIVE felt very very weak. I have recently replaced the cam position sensor as well as the ICP sensor. I'm at a loss, I plan to do a ZF6 transmission swap very soon and this is only making me panic even more.
I never dog the truck, take it mudding, etc. Oil is changed every 3-4,000 miles. I did however get it scanned a while back and I believe two codes came up for two pistons, also did an injector buzz test and they all sounded strong.

On the way to work, the truck seemed to have a miss at idle and the CE light came on. Long crank to start leaving work, and truck starts losing power and eventually died. No smoke while it was losing power. Towed it home and checked the fuel pump and lines for blockage and found nothing.
2003 7.3 F-250 430K miles
strong cranking but no start no smoke out exhaust
Oil changed recently
IPR changed
Both UVCH gaskets and pigtails have been repaired.
ICP sensor and harness changed, also disconnected no change in cranking.
fuel filter changed today (no oil in bowl)
3/4 tank of fuel
dash gauge for lpop goes up to normal range during cranking and oil light turns off.
WTS light comes on and turns off as normal
tach gauge moves up between 100-200 during cranking
fuel pump turns on and pressurizes system like normal and turns off.
Ordered AE for the truck, and it directed me to the passenger side bank high open. Fixed the harness on that side and still nothing.
Sent off the IDM and it passed with flying colors
So now i'm leaning towards the HPOP, but would hate to fork over the cash for it and still not get anywhere. I'm going to take the valve covers back off and check the discharge ports for the injectors tomorrow.

I have a 2005 Ford Focus ZX4. It is a stick. For the past month it has been having trouble starting, the example I will turn the key and it will try to start up, but doesn't. Then it will start but it is weak, sputtering, not wanting to really start, but I give it a little gas and it is fine. The last time it happened, It started after about 8 tries. I was driving a little ways and all of a sudden the radio/cd player quit working flashing a message that said low battery. Then all the lights in the car started to dim out. The headlights started dimming out too.
I did make it home, turned it off and when I tried to start it again all I heard was a click, click, click noise. It is at the shop now. I thought for sure it was the alternator, but they said the alternator is testing fine and once they 'recharged' the battery it is fine too. They drove it around for about a half an hour and they said it was running fine. What the what? They said they did have the problem getting it to start that I did, but only once. Now they aren't sure what the problem is. I don't want to get ripped off! I also don't want to have to fix something that isn't broken. I

I have a 2005 Ford Focus. It has recently begun losing power. The RPMs will race while the speed steadily drops (especially on hills but it's started doing it on lesser inclines). It's been accompanied at times by my car shifting hard and the overdrive off light flashing orange until I pull over and turn it off. When I start it again the light clears. There are no other warning lights. I've taken it to my mechanic twice. He's serviced the transmission, replaced the spark plugs and the fuel filter. He's run the diagnostics and nothing is showing up.

I have an 07 explorer that has developed an new problem. While driving, I lose all throttle, regardless of whether I'm accelerating or just cruising along. I've checked the vacuum lines and fuels filter and pump to no avail. It. Has progressed from a once a week to the point that it's not drivable.
