When it's cold outside my car will start up, but not stay running. The only way I can get it to stay running is to keep my food on the gas for up to five minutes. Once the vehicle is warmed up, it stays running. If I start it every hour or so, it will run fine. It's just when it's been sitting out in around zero degree weather overnight for example.

View 2 RepliesThe colder it gets the harder it takes to start my 2000 Ford Explorer. Have read that it's the Intake Air Temperature Sensor.
View 3 Replies2000 Sierra 1500, 5.3L engine. When he starts it in the cold (below 40 degrees) at first hits 1000rpm, then immediately drops to 400-500rpm. The idle is rough and wants to die if he tries to drive it. However after 10-15 minutes and the eng warms up, its fine no problems at all. There is no codes, so the scanner we had didn't tell us anything. He had cleaned the TB and intake system with cleaner, no dice. He also disconnected the IAC while it was idling rough, that didn't change the way it ran at all. We would like to toubleshoot it more before we start throwing parts at it.
View 1 RepliesI have a 1998 Ford Explorer. 215K miles. Original Owner. When it is cold there is a very light leaking of brake fluid at the base of the master cylinder where it meets the brake booster. This morning it was 14 degrees and there was a much bigger leak. Filled it back up and went to work. I'm thinking its about time I took care of it. I've had the the master cylinder replaced once at Goodyear Auto Service Center years ago.
I'll post a picture later but having the leak where it is. Would that be a replacement of both the master cylinder and brake booster? How can you tell? Or is it better just to change out both. Having done more work on my car over years I feel I can do the work myself. Plus the master cylinder is only like $50 and $60 for the brake booster.
I have a 1999 Ford F-150 XLT, with the 5.4 and a 4spd auto. 172,XXX miles on the clock and i have owned it starting on April of 2014.
Tonight driving home from work, it took some time on the highway (4 miles) to shift into top gear. When you lift off the gas pedal after reaching the speed limit, normally the truck will shift from 3rd to 4th no problem. When I let off the pedal, there was no gear change.
It took sometime for it to shift up. When downshifting on the exit ramp, there was nothing abnormal. Where I live it is 19 Degrees Fahrenheit and this is the beginning of the cold snap that will last well into mid-January of next year.
Have a 2001 F150 FX4x4 and since the weather changed and started having days below 40 the truck has started running rough for about the first 15-20 miles. When you first start it starts like normal for first 3-5 min and then it starts loping real bad like it has a cam in it!
View 5 Replies1988 Ford E-Series Van ford van starting problems I have a 1988 ford van e150 302 that wont start. when it did start, it ran rough, then progress to needing start fluid to start. Now it cranks but wont start at all. it sat for almost a year with additves in gas but it does smell now unlike normal gas. it has sta-bil and gas line anti freeze as additives. A rail mount high pressure pump was put on two years ago. Could the hi-pres pump been installed backwards? Now it will not start even with starting fluid, just cranks and tries(pops and backfires a little sometimes). I towed in to a mechanic to get diagnosed.
In regards to the 1988 ford van start problems, the mechanics said that fuel is bad and needs drained, that in tank pumps seem to have pressure(low pressure pumps). the rail (high press pump) they say tests 15-20 psi only. the want to drain tanks, replace pump and "go from there". They also said a multitude of problems can happen from "bad gas" ranging from injectors needs cleaning to bent push rods, lifters and crank shaft can be damaged. All may need cleaned, fixed or replacing. does this seem a little fishy ? Could it need the timing set? Or injectors bad?
My idle seems to always be somewhat rough whenever I put the heat on in cold weather. While in drive I'll come to a red light, heat will be on and I'll stop. The. my idle will bounce down then back up. I shut heat off to test and it only does it while heats on.
View 5 RepliesI have a 5.0 Explorer 1998 and it has a problem for which I cannot find a definite solution, everyone says a different thing. The problem is that when the weather is hot, sometimes the engine does a strange thing. You ride the car for some time, especially if you do it on a high speed so the engine is really hot (but no overheating symptoms) - and then you kill the engine and leave it for a few minutes - to walk into a store, let's say.
After that you attempt to start the engine... sometimes it starts, but there were several times when it refused to catch, it cranks, at first tries to start, but stalls... then it just cranks without even attempting to start. And I had one occasion when it stopped working right in the middle of the road while crawling in traffic, but it was really HOT outside. Luckily, all other cases were in our town, so I could at least walk home. So, the problem seems to overheating of something, as in normal or cold weather it never happens. And every time, after the car is left to stay in place for some time, an hour or more, cannot say exactly - it starts perfectly!
I am really tried of this and want to eliminate the reason. But I am hearing so many different opinions about this problem. I thought that it could be the overheating of the fuel pump. But then it would stop working while moving, not after you shut the engine off and the pump cannot be still working and overheating. The only place where the heat can build up when you stop and turn the engine off is under the hood, as the fan stops, the coolant pump stops and the air isn't blowing as the car isn't moving. But the pump is in the tank! And I never ride on empty fuel tank, I always keep some level, lately I tried to keep it even higher, but yesterday it refused to start when the tank was almost half-full. Also, if it was just dying - a dying fuel pump gives certain symptoms like slow acceleration, engine shaking and trying to stall when you press the pedal, sudden stalling, uneven idling etc. In this case, nothing like this. The car's behavior is absolutely normal, acceleration good, normal idle. It happens ONLY under certain conditions, involving heat.
Other people say that it can be due to low pressure in the fuel ramp and the gasoline is starting to boil at some moment, when the temperature under the hood rises to a certain point. As a reason they name the pump (but as I said, I doubt it) or the fuel pressure control valve - don't know its exact name, it's a valve which maintains a certain pressure in the fuel ramp and releases excessive pressure by returning some fuel to the tank. However, when this valve gets stuck and doesn't maintain pressure, it mostly influences the cold start, as the fuel pressure drops and you have to crank for a long time while the pump is building the pressure again. But my car has never had any problems with the cold start, it's always instantaneous. Also, when this problem occurs and you start the engine after it cools down, it catches instantly which means THERE IS pressure in the ramp. So I don't believe in low pressure, gasoline boiling and resulting vapor jams.
And finally, I read that it may be caused by defective/dying engine temperature or crankshaft position sensors. As for the temp sensor, I will replace it tomorrow anyway. I am also thinking of having a look at the crankshaft sensor, where it's located on 5.0 V8?
I have a 1988 Camaro with a v6 engine and it has 70,000 original miles on it. problem is that it is hard to start when its cold so i changed the fuel filter because i read it can be the problem because it might be clogged. so after changing the filter it started and ran really good but after a couple of days now it starts to hesitate and stutter on take off and thru out the whole drive. so far i have changed the distributor cap and the ignition control module but still has same problem.
View 4 RepliesI have a 2001 Toyota Sienna xle that started running rough when the weather turned cold. When started, the car idles very high and will not shift properly until it was been running for around 5 minutes. After that it will run well for about 10-15 minutes and then begin to run rough or poorly. The problem is very noticeable at low speeds and when stopped. It never actually kills, but it feels like it is going to. At high speeds it is less noticeable but occasionally you will feel it jerk or chug like the transmission is slipping or a belt or something.
I took it to a mechanic who checked the codes and found that the ignition coils were supposedly bad. I say supposedly because they replace three of the ignition coils and the problem still persists. I then took it back to the mechanic who then told me it was the oxygen sensor. The o2 sensor was replaced and the problem is still there with no noticeable improvement. I again to it back to the mechanic who tells me that they scratching their heads.
I have done some looking around on the internet and have found some discussions that seem to have some promising leeds and actually last weeks car talk show had a caller who described a similar problem. The guys told him it could be a oxygen sensor but they thought a better possibility would be EGR valve or a vacuum leak. Not sure if this sienna has an EGR, but I plan to suggest looking into it to the mechanic. Also, I found some discussions talking about the idle control valve and the engine control module.
I took care of a vacuum leak on this car but I still have an Idle issue on a cold start it doesn't wont to idle at all once I get it warmed up it idle's in park and Neutral fine as soon as I put into drive it want's to die I can keep it going by letting of the gas and then pushing the gas peddle again and take of quickly. Stopping at red lights I have to hurry and put it into neutral or it will die having the ac on makes it worse.

View 2 RepliesMy truck is a 1995 Explorer 4.0 150,000 miles, 5 speed.
Problem - Rough idle : when cold it's worse and will stall and choke a little. When warmed up it just has a rough idle but will not stall and stays at a pretty constant RPM. It's very tolerable when warmed up but still not right. It drives fine once off idle. No black smoke that I can see. Power may be just a little off but I would not bet on it. MPG seems about normal but haven't been on a long enough trip since problem started to tell for sure. Also longer than normal cranking on occasion.
Diagnostics so far : Fuel pressure is at 32 PSI, vacuum off regulator it's at 40 PSI. Not sure about key on only as I don't trust the autozone loaner gauges. You have to fiddle with it each time before it will read. Leak down after 30 minutes was about 4 PSI
No Check engine light ever. KOEO test shows no hard or on demand codes, I get the 111 pass. From CM I get 336 and 45.
336 is EGR related and my looks pretty rusty. I put a vacuum pump on it while running and the EGR held vacuum but had no effect at all on idle, I was expecting it to get worse as I opened the EGR so it may be stuck.
Searched high and low for vacuum leaks by ear, visual and with starting fluid all turned up nothing.
Actions so far : Replaced plugs, wires, IAC, and fuel filter. Cleaned MAF sensor and throttle body plus ran lucas fuel injector cleaner through it.
Next steps : I've got the EGR but it's so rusty I am sure I'll break the tube it bolts to plus I don't know it that alone will cause the rough idle. Will the DPFE sensor and/or EVR create a rough idle yet not turn on the CEL?
Thought about changing the fuel pump and/or regulator but the numbers are not terrible. Agree?
Thought about changing the intake gaskets but don't see any leaks.
I picked up my 05 F350 dually 5 speed w/ the 6.0 powerstroke motor in august... It only had 38k on it when I bought it... its got 43K miles on it now...
Ran great in the warm weather but ever since it got cold out its been a struggle. It was running rough on the way home and kept stalling while i was driving it.. (acting like it was starving for fuel).
I went and replaced both fuel filters and started the truck... let it warm up and it stalled while sitting in my drive way and haven't been able to start it since...
I have fuel additive in it but since I don't drive it all the time (maybe 3 times a week for 30 miles) could it be possible that the fuel is gelling?
I was going to check the EGR valve tonight...
I have the LED mod and several weeks ago, my LED stopped indicating and the truck would not start in cold weather unless I jumped the terminal on the relay. I replaced the relay and while I was tightening one of the small lugs, the one towards the nose of the truck, I felt it break.
The truck acted just like it had been for the weeks prior, if I didn't jump the relay, it wouldn't cold start, so I assumed, because I had broken that small lug, it wasn't getting the signal to turn them on.
So what now? obviously the GP's themselves are working, as the truck starts when I jump them. But for some reason no signal is getting to the relay. What do I need to check to see what is going on between the PCM and the relay?
"Vehicle with smart key system: The indicator light flashes after the "POWER" switch has been turned OFF to indicate that the system is operating." I have noticed that my immobilizer light will not blink when it has the no start issue. usually when the key is out the light blinks but when it won't blink.... it won't start.

View 6 RepliesIn Jan my 94 Toyota Camry started having issues with starting- for instance, I would run an errand for 10 minutes get back in the car and it wouldn't start. However, this tended to be random. When this problem happened more often I took it in and they said I needed a new starter so I got one (Feb) and didn't have any issues for a month, but then began to have the same issue on and off again. I took my car back in for the second time and they said it must have been a bad starter. They gave me ANOTHER new starter (Apr) and my issues continued soon after. I took it back in and they didn't have an answer for me other than the starter was good. Took it to another mechanic and he had the car for two days and could not find ANY ISSUE with the car. I let it brush over during the summer months because I never had this issue (June-Aug) and now that it's gotten cold again I'm having this problem.
Few things to note: -Anytime I have this issue I'll hit the starter with a hammer and it will ALWAYS start. This has been the case since January.-It ALWAYS starts in the morning and when I get back in my car after working all day. However, if I were to run errands in the morning or at night it would not start with the stop and go. -This only happens in the cold months -They tested the newest starter and they say there's nothing wrong with it.-Within the past two years I've had MANY things replaced on this car and any shops I've taken it to say it's a great car with no issues they can find.
