Cadillac - Seville :: Intermittent Stalling Occasionally When Slowing Down Or Coasting
Jan 24, 2013
I have a 1998 Cadillac Seville STS which has recently developed an intermittent stalling issue. Here are the details:
Happens occasionally when I'm slowing down or coasting, such as turning into a parking lot or going around a sharp entrance ramp-Has not yet happened during acceleration-No bucking or jerking while accelerating-No apparent warning that it is going to stall-Has happened once each of my last two trips
The first few times it happened my fuel level was pretty low, and one of the times I tried several times to restart it and it would start but die right away. I managed to get it started again, then I filled the tank and tested the fuel pressure at the rail, and I got 45-50 psi with the key turned but without the engine running.
After that time, I have not had any difficulty restarting it when it stalls. I held the valve in basically the same position that it is installed (meaning I didn't turn it upside down) and sprayed in the opening with throttle body cleaner (not carb cleaner). I then used a "pipe cleaner" to clean the inside, and I also worked the plunger up and down after I sprayed it.
I had a few "false alarms" in the past thinking it was fixed, so I wanted to wait until I was sure before posting. I now have to lose the habit of constantly glancing at the tach to see if it's about to stall. It would be interesting to know why cleaning the EGR valve fixed it.

On occasion, my 2003 Cadillac Seville SLS will indicate that the car is low on oil and I should stop driving. When I checked the oil, it has never been low. Prior to this happening, the gas hand began to dance between 1/4 of a tank and a full tank. I am not sure if these issue are related or if I have two separate issues.

The service engine soon sign came on awhile ago. I immediately took it to a garage and they said they can't find a code. My mechanic friend checked it and found a lean combustion condition. What could be causing this issue and what can I do about it. This yellow service engine soon light is driving my nuts!!!

I have a 2001 seville. The problem that I have is that the abs and traction icons come on the dash sporadically. When this happens the ventilation system shuts down. When the lights go out ,the ventilation system works fine. The dealership tells me that the two systems are not connected. They tell me that I need a new module. I would like to hear other diagnoses of the problem and repair.

I have a 2004 Cadillac it started to miss when your idling, a check engine light when on and it was #5 plug not firing so I changed the plugs in front 4 of them and also bought a coil pack and replaced that, but it still misses. What else can I check before thinking its a sticky Valve or internal engine problems.

I have 2002 Cadillac Seville SLS. From time the icons for the brake and abs do not go off after the car starts up. I'll be driving for anywhere between a few minutes to an hour or so and they well go off and an audio tone goes off. Sometimes they will not come back on for the remainder of my trip, at other times times they will appear again then go off again. There is no indication that there is anything wrong with the brakes. Also, when the icons go off and the heater is on the fan will accelerate. What may be going on?

My 2004 Accent GLS has stalled intermittently for me and my daughter several times. However, the mechanics cannot replicate the problem and it is not revealing any codes when analyzed. Additional details would include the fact that the stalling incidents have occurred while sitting in slow traffic or when slowing when approaching an intersection. After it stalls, 3 of the 4 times it started again within 10 minutes.
This last time, it took several hours before we were able to restart it. There is no fuel smell when restarting. The check engine light is not on. The problem actually began as a "failure to start" problem, which I thought could have been a faulty battery as, even though the engine was turning over and I didn't really suspect the battery, it would start when jumped. The problem then moved to a stalling problem.
So far, I've replaced a battery (probably a waste), the mechanic found some frayed wires coming from the ignition which he fixed and I'm now having them replace the crank sensor. Does replacing this sensor, though no code is apparent, on the right track? Should I be focused elsewhere? Is there a common 2004 Accent problem? It's my daughter's first car and only has 67,000 miles on it, so I'm in no hurry to get a new car!

So I've noticed something on my 2015 Elantra that I haven't noticed on my previous car (Corolla). When I'm coasting at low speed (i.e. when I see a stop sign/red light I'll just coast until I'm closer and then press the brakes) it feels as though the brakes are sometimes being pressed when I'm not actually pressing them. Is this normal? Why does it do that? I'd like it to not do that as it's kinda annoying. Sometimes it "brakes" enough that I actually have to press the gas again otherwise the car is going too slow, which defeats the purpose of why I'm coasting in the first place as I do it to save some gas.
My Elantra has an automatic transmission if that matters.

My Caddy 2002 keeps stalling at different times. This last time (Saturday night) I was on the freeway in the middle of 10 lanes of traffic, dark and the car just died. No lights; no power, nothing. I managed to get to the side of the road and was able to restart it again. This has happened about 10 times in the last 5 years and I have paid to have it repaired about 4 times paying about 340 each time. At first they said it was sensors and now they say it is the ignition. Very frustrating and scary on the freeway.

I have a 1992 Cadillac Brougham Hearse (Eagle Coach Co.) with a 305 V-8 that I’ve been having the following problem with. It had gotten to where it would start up, run at idle for 10 to 15 minutes and start cutting out, sputter and then die and would not restart afterwards. The next day, go out, starts right up and same thing after idling 10-15 minutes, cuts out and dies. So, I immediately think, fuel filter and or fuel pump! So, I replace the in tank fuel pump, sending unit and the in line fuel filter. Results remained the same. I’ve even swapped out the coil, ignition control module (ICM), starter and fuel pump relays from a like car and am still having the same results. Fuel gauge is reading between ¾ and ½ tank of fuel. Wondering what to look at next?

Have this problem where Santa Fe when coasting in a parking lot or driving slowly on the road, that their is a bit of a slam into second gear in the auto transmission?
Reason I am asking this is that I have this problem and own a 2013 KIA Sorento, but understand the Santa Fe V6 shares the same motor and tranny. I also read that one long term test of the Santa Fe on the web had this very same problem, but in the end after happening several times, stopped happening.
After reading much info, I ordered a Transmission Temp Sensor as this seemed to work on some cars, but it's really a hit or miss thing.

I have an issue with a 1993 Ford Tempo. It is owned by a auto parts store and is used for deliveries so it gets a lot of use from day to day. Several different mechanics have looked at it and no one can figure out exactly whats wrong.
The issue is this - The car stalls out at about 2 or 3 oclock everyday after being used for deliveries starting at 9 oclock. It will stall while idling in park, while stopped in drive, while coasting/accelerating in drive. The temperature is normal. Is will start to idle and run very rough and the car is less responsive to the gas pedal about 10 minutes before it stalls.
Once it stalls, if it is allowed to sit for about half an hour it will start and run fine for a little longer but eventually stall again. After it sits for a few hours it is fine to run for a few hours again. If you try to start it right after it stalls the first time the engine will turn over but stall out again in a few seconds, if you keep trying to restart it it will eventually not even crank. Also it will occasionally stall like this/run rough in the first 10-20 minutes of driving.

I'm having a problem with my mom's 2005 Accent. It starts up just fine when cold, and will run for 15-20 minutes just fine, sometimes longer. Then, usually as you're slowing down, the engine just turns off. No bogging, no sputter, just turns off as if someone turned the key. Sometimes it will start back right back up, more often, it will need to sit for 30 seconds to a minute, and then it will fire back up. After that, all bets are off. Sometimes it will run again for 10-15 minutes, sometimes it will idle rough and die. I'm leaning towards a coil pack, but I'm sick of throwing parts at this. The last time I got it to idle roughly, it threw a random misfire, and cylinder 1, 2, and 4 misfire codes. I've changed out (in rough order) MAP sensor, the fuel pump (no fuel filter in this model), TPS (threw code for this), spark plugs, and most recently the Crankshaft Position Sensor. I'm not sure how to test the coil packs.

This just started over the weekend. It's stalling. It does it mostly when I let off the gas and start slowing down. If I give it gas, it seems to straighten out for a minute. It has done this a couple of times while driving also. It sounds as if the engine speeds up and then slows down and stalls. The check engine light is on also. It went out yesterday and then popped back on today.

We purchased our 2011 Jetta SE Automatic brand new - first people to drive it - and have had virtually no problems up until this summer. The car has stalled on us dozens of times now and been to two different dealerships for service a handful of times and no one knows what the problem is. We found that the car typically stalls when we're slowing down; however, it recently stalled when we were in Park. When it stalls, the steering wheel locks up, the breaks are nearly impossible to push and everything seems to shut down except the radio. We're virtually a sitting duck for other cars.
When this happens, we're able to put the car back in park, turn it off and back on and drive fine for a while. It seems to be happening more frequently but the dealership hasn't been able to replicate the issue - there are no codes left on the computer and they've literally taken the car apart and can't find anything wrong. They've even 'driven' it for 200 miles and still, nothing. Initially we were told it was bad gas, then we were told it was an operating system update. Now they're trying to tell us that it's our driving style but multiple people in my family have driven the car with the same effect - stalling spontaneously while slowing down, stopping or trying to break.
We've also noticed skipping or slipping between gears when we're at higher speeds but I'm not sure if that's related. It almost feels like your foot falls off the accelerator or slips while you're driving but instead you're actually applying constant pressure.

Car has been stalling when stopped sitting in driveway or when slowing down for a red light or stop sign. Sometimes starts right away others takes 20 minutes. No codes no service engine light. Being told camshaft sensor crankshaft sensor egr valve. Got all data at library did egr test all indicate it is good. Did not have enough time to print out info on the sensors

I have a 4 cylinder '98 Toyota Camry with 82k miles on it. I got the car second hand from a family friend 7 months ago. About 3 months ago, my engine would sputter and then shut off when I'd start slowing down below 30mph and stopping at lights after I'd been on the interstate. Issue occurs only when I've accelerated quickly during that drive (ie accelerating hard to go up a hill to merge or to pass a slow car).
When I need to stop, if I'm fast enough to get the gear in neutral, hold down the break and rev the engine at the same time, then it most likely won't shut off. It's like trying to do CPR on my car... The spark pugs have been replaced, oil changed, and fluid levels checked but the problem still happens. What could be the problem??

I have a 2005 Ford Escape XLT 3.0L V6 which I bought 6 weeks ago. It has 103,000 miles on the clock. I mainly use it for going to school and getting around town etc but on Sunday I had to take my parents back. It's a round trip of 230 miles. Weather was sunny. Traffic on the Expressway so a lot of slowing down, stopping, setting off cycles but no issues. On the way home, about two toll plazas from my exit on the I90, I noticed that the engine sounded and felt like I was driving in a higher gear than that required for the speed I was doing (5 mph). It's an automatic (which I'm not used to as I've always driven manual) so I don't make any gear changes but if I'd been in a manual, it felt like I was in 2nd when I should have been in 1st. Does that make sense?
Anyhow, so I managed not to stall at the toll plazas but when I exited, the engine stalled 3 times (twice at intersections and finally when I pulled up outside my house). There is no problem starting the car after this has happened. I called my local autoshop who said to bring it in Tuesday so I didn't drive it Monday. Tuesday morning, it felt exactly the same when I was slowing down for traffic, intersections, turnings etc. The autoshop had it 3 days and couldn't find anything wrong with it. There is no data stored on the computer to show any of this happened and it has driven fine for them when they've taken it out. Beyond frustrated! I know what I heard and felt. Someone mentioned the overdrive staying on but I don't know what that means.

During an extended drive of the new ride today, we noticed an intermittent vibration when coasting downhill around 60MPH. I popped it in neutral and the vibration disappeared completely. Also, it stayed vibration-free when placed back in Drive, without touching the gas. But as soon as throttle is applied and then you coast again, the vibration reappears.
This points to a condition that only happens when the torque converter is locked, which could be a vibration originating within the transfer case that once coupled to the engine via the locked torque converter uses the engine as a tuning fork, resulting in the vibration. The L-SB-0013-12 AWD Vibration TSB mentions an ECM recalibration, which likely changes the torque converter to unlock whenever you lift off the gas pedal. Is this correct?
I also remember reading about the other TSB, where the "magic expensive fluid" in the transfer case gets changed 3 times in rapid succession. This would address chattering clutches within the transfer case, eliminating vibration at the source vs. masking it by unlocking the torque converter.
We also noticed a misfiring sensation under light throttle conditions at around 40-50MPH. I'm wondering if this is in fact the transfer case clutch chatter issue also...since the 60k spark plug replacement has already been done.

2002 Honda Accord, 4 cyl., will stall unexpectedly when coming to a stop or slowing down. It will start to shake and hesitate as one is slowing down from 35+ mph, then will stall at the stop. Has some trouble restarting, but when it does, everything seems to be fine. No codes are left, and my mechanic suspects dirt or something similar is contacting the fuel injector(s) on a sporadic basis. I did replace the spark plugs as they were due at the time this first showed up, but it has happened twice since in a 3 month period.

My 1996 Dodge Grand Caravan has developed a curious problem. It intermittently stalls, sometimes when slowing down, sometimes when going up an incline, sometimes on straightaways. Once stalled, it often won't start again until it has sat for 20-30 minutes. Then it starts right back up again and drives perfectly normally until the next time that it stalls-which can be days or hours. The problem is definitely getting worse--six times today. Warmer temperatures seem to exacerbate the problem. Again, the engine runs very smoothly up to the point of the stall. My mechanic was unable to replicate the problem and his diagnostics showed everything to be normal.
