Ignition switches on Aleros are notorious for going bad and causing the exact problem you describe. The next time it happens, try turning the ignition key back and forth slightly. If everything starts working again, then have the ignition switch replaced.

I know this sounds stupid, but I replaced my pcv valve recently and shortly after I began having the check engine light and some sputtering at starts. I replaced the grommet and it went away. I think the replacement pcv was a touch smaller and there may have been a vacuum issue. I had it hooked up to a computer and showed no issues. Cheap and easy maybe fix???? Hope this helps.

When in stop and go traffic yesterday, the car suddenly died. It restarted, but would not maintain a normal idle unless kept my foot on the gas. Once we got out of the stop and go traffic it ran ok,


It will probably be OK. But if you can, find a can of brake cleaner and a toothbrush. Remove the air plenum from the throttle body. Use the cleaner to clean the throttle body inside and the back of the throttle plate as best you can. Especially around where the throttle plate sits. It will take a second or two to restart the car. Once started spray some of the brake clean into the throttle, rev it up to keep in running. This will help stop the dieing out.

Why does my 2009 Sedona Kia loose power when I slow down or stop at a corner or traffic light?


It could be the Electronic Stability Control (ESC) is inappropriately kicking in. Another possibility is the throttle position sensor. In any case, have it checked out soon so you don't ending up stopping with traffic behind/across that isn't going to stop!

How can we achieve fuel efficiency while driving my car?


Do these these things
-Inflate your tyres to correct pressure or a little over, when cold
-Don't accelerate quickly or rev the engine up , most especially when cold
-Try to drive smoothly in traffic with a light foot, not jerkily
-In cars with small engines A/C will consume more fuel
-Fill up with the least ethanol that is legal, and that your car will tolerate. Consult your driver handbook. Efuel gives less economy
-Don't cart heavy loads around in the car for convenience' sake. Take them out till you need them.
-Don't put roof racks and travel pods on when not needed. These create drag
-On the highway travel at 10% under the limit. Less and you will irritate others, but high speeds increase fuel consumption greatly

Can wheels and tires affect gas mileage?


Well braking will drastically reduce your fuel economy, as of course this is taking the inertia energy of the vehicle which you built burning fuel in the engine and then reducing that and changing that inertia into heat.Your tyres do pretty much the same thing as they are a trade off between low rolling resistance and grip which helps you turn and brake. The reason trains have steel wheels is because they turn on tracks, although their braking distance is severely affected. You need to stop quickly in a car and corner safely enough to not end up in a ditch each time you take a corner, and this is why you have high grip rubber tyres on your vehicle.Typically the best way to reduce rolling resistance with your present set of tyres, is to keep them inflated up to pressure, or even slightly over pressure, which most vehicles can afford to do. (arround 5 P.S.I. will do)Other fuel saving techniques which can drastically improve performance are:
1) Remove excess weight such as the spare wheel, jack, wrench etc. Carry a can of tyre sealant instead for minor emergencies.
2) Remove any excess baggage which doesn't need to make permanent home in your car.
3) Remove any unused bike racks, roof racks and spoilers from the car.
4) When driving keep plenty of room between yourself and the car in front. This allows you to use lighter braking force when cruising at speed and also allows you to get off the gas earlier when stopping.The same goes for looking well ahead in the road for red traffic lights or stop signs. Get off the gas early if you are going to be stopping up ahead anyway!
5) Best fuel saving tip overall; plan your route ahead of time. If it's a route you are unfamiliar with then driving around in circles trying to find it is not going to save any fuel at all. Planning ahead and travelling during low traffic volume periods can save a huge quantity of fuel.

6) Share your supermarket/shopping mall trip with a neighbor or friend. You can share the cost of fuel and reduce the number of vehicles on the road at the same time.


7) Manage several errands in one long trip. Cars by far use the most fuel on cold start and during cold running, as well as suffer around 80% of engine wear during cold start only. By keeping your car up to temperature on a longer journey, you can improve your average fuel economy and reduce wear and tear to the engine internals.


8) When accelerating up to cruising speed, use around 75% of the available engine power. Only reserve this method for times when there is little traffic ahead and you can maintain safe braking distances ahead. Getting up to speed more quickly actually saves fuel in the long run. I really don't mean burn the rubber off the wheels and burn your clutch out kind of acceleration though, so take it easy!

My trooper's engine stops after traveling for sometime. It stops during idle mode, like getting stuck in traffic. But it starts again. It happened to me while driving home to Pangasinan for 4 times.....


This happened with a pt cruiser I own. As it turned out the motor was overheating due to
an intermittent cooling fan. It would heat up and cause the car to stall at lights. It was fine on the highway since the fan is not used.
I replaced the cooling fan and have never had a problem in two years. (also make sure
coolant levels are correct in the radiator as well). Hope this is useful.

Have a c200 KOMPRESSOR Year 2001, 1988cc, recently i encounter a problem. Its said P2001 0638 throttle valve actuator proble. I travel around 350km long distance last week, and when i pit stop at the rest...


is possible that this term is used in the idle air control valve is the firs thing that came to my mind since it is a valve and also an actuator. this would be mounted in the throttle body close to the accelerator linkage it looks like a small electric motor and has a connector to it it controls the air that comes in the throttle and sound like you described exactly a faulty or dirty idle air control valve or actuator. there is cases when they get dirty and get stuck on and off and a good cleaning will fix it also when they're bad but is have to be inspected to determine. i hope you find this of use and also i'll be happy to hear the outcome. thank you for your time and good luck.

As I slow down or stop at a stop sign or red light it turns off. It drives good in a highway, as soon as I get out of the highway it turns off, or as I'm driving in the city. Took it to the mechanic can't...


Does it happen in stop and go traffic? If the answer is no and the only time it does happen is at speeds at about 40 mph's or better then its the brake switch its failing to cancell out Torque converter clutch solenoid (TCC). If it happens at all speeds take the vehicle to a shop that does SCOPE TESTING NOT A SCANNER this way they can hook the vehicle up to the SCOPEMETER and drive around with it to see what turns off (other than the vehicle) and causes the vehicle to die.

My electronic throttle control warning light came on what is wrong with my 2007 Sebring?


I have an 08 Sebring and mine has been having the etc light come on and the car will stall..with little to no notice. It's at the dealer right now and they can't figure out what is causing this because the light doesn't stay on once you turn off the car and restart it. It's kind of relieving to me that someone else is having this problem. Hopefully Chrysler can figure out what the deal is with this!!

When trans. is warm after extended driving the up shifts are very hard. This only happens during extended driving periods. Around town everything shifts fine.


Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check Throttle Position Sensor (TPS) for smooth electrical response. If the response is jumpy or erratic at all, replace TPS. Good luck Auto Zone or Parts Source has this part and can be replaced with in 20 min. Both parts store will have the step by step instructions and i believe the cost is around $65.00 for the TPS which is better then a transmission replacement.

You have one of two very common problems.
Number one may be a stuck open EGR valve
Number two would be a failing Idle Air Control valve (IAC).
Try this: Open the hood & locate the EGR valve, close to the firewall, behind the intake. Find & take with you a small hammer. The next time that it happens, open the hood & tap on the EGR valve. If it is sticking "open" the tapping may dislodge the carbon particles that are keeping it open.When the EGR valve is open, exhaust is getting into the intake at idle, and this will def stall out the car.
There is no repair to the IAC valve, it would need to be replaced if it is bad.
One of these two scenarios will cure your problem, I see it every day.
