Car Stalling Problems
When your car’s engine stops when it’s in idle or is accelerating, then your car has stalled. Almost all stalling problems stem from poor fuel-gas mixture, out-of-tune fuel injection or fuel contaminants.

What makes your 305 engine sputter and go dead when you accelerate?
probablly not getting fuel check your fuel filter unless timing is off
Why would a car stall when you step on the gas?
It's probably not getting enough fuel. Check the fuel filter but more likely the fuel pump.
In addition to lack of fuel it could be a monster vacuum leak. Does this condition improve as the engine gets to normal operating condition? I struggled with a leaky intake manifold gasket for two winter season. After six trips to local mechanics and as many reasons it was discovered at the local Lincoln dealer...by
accident. Vehicle has 180k miles now and starts, idles like new
What is the warning light transit connect orange symbol left side?
It is hard to say what the orange warning light transit symbol on the left side is. It would depend on the year, make, and model of the vehicle. Most vehicles have a users manual that have a listing of the symbols to tell the user what each warning light is for.
Blazer stalls while driving and reaches normal temp?
If it is a newer model (no distributor) then it sounds like the Ignition Control pack is bad. If it is older (with a distributor) then replace the Ignition coil inside the distributor cap.
First thing, check your vacuum hoses. Second, unhook your battery for about an hour, then hook it back up. The computer may need to reset itself. After that, you're on your own.
- The most common vacuum hose issue with a focus is the PCV hose wher it goes to the back of the intake manifold. You should check that, but ususlly if you have a vacuum hose problem, it won't show up as a P0301 and a p0304 fail code, like you have. It will ususlly be a p0171 which is a lean code.
Since your fail codes are 301 and 304, you should actually check to see if you have ignition fire to the #1 and #4 cylinders. Evidentally you already checked that and didn't have fire, otherwise, I wouldn't think you would have replaced the coil pack, without doing that simple test. But in case you didn't, then you need to. If you have no fire to those two cyliders, and you are sure your plug wires are good, then likely there is something wrong in the PIP signal to the coil pack from the PCM. On the coil pack, there is a connector into the side with three wires. One is a shared PIP(pulsed ground signal) to the towers for cyls #1 and #4, one is a PIP to #2 and #3, and the third wire is a common power input. PIP is a pulsed ground from the PCM. The PCM pulses the ground "on" everytime it wants to fire either the #1/#4 cylinders, or the #2/#3 cylinders. So the #1 and the #4 plugs both fire at the same time, and so do the #2 and #3 plugs. The cylinder that isn't on it's compression stroke just receives a harmless "waste" spark.
If you DO have spark to these plugs, then you could have bad plugs. But if you DO NOT have bad plugs, then your problem IS NOT ignition. If your problem is not ignition, then you could have fuel injector issues or engine compression issues.
One thing is certain. When you find and fix the problem, you will know it. The engine will straighten up and run fine. No "resetting" of the PCM is necessary, other than to turn off the check engine light. "Reseting" the PCM does not fix problems. That is a common misconception.
You have what is referred to as a "misfire" evidentally on the numbers 1 and 4 cylinders. Four things cause a misfire: ignition failure(spark), fuel failure(lack of fuel), engine compression failure to those cylinders, or coolant getting into those two cyliders which is causing the fuel to not combust.
RECAP: Start with spark which is coil, plugs, or plug wires. If you don't have spark, find out why. Is it plugs, lug wires, or do you have no PIP signal on that circuit to those two coil towers.
Second, if spark is not your problem, then check engine compression. Get an engine compression guage and test all four cyliders. All will be around 150 PSI if they are good. Any cylinders that are under 100 PSI are a problem.
Third, make sure all four fuel injectors are firing.
Do those three thiings, and I'll bet somewhere along the line, you will find your problem.
Your alternator could be going down the tubes. If I was told correctly, your rpms jump up because it is trying to recharge...
What are the symptoms of a failing oil pump?
You dont want to feel OR hear the symtoms. If you think you have a bad pump unscrew the oil sender and screw in a pressure gauge.
How do you stop driving in reverse?
Come to a full stop, put on the handbrake, change the gear to first (or drive) and begin driving forwards as normal. Do not try to put the car into a forward gear while you are still travelling backwards.
My 97 Sonoma was doing the same thing and a good tech found it was a bad ignition switch. The truck runs great again.
Will a bad PVC cause the idle to go up and down about 200 RPMs and stall and die at a stop light?
A faulty PCV valve can certainly cause idling problems, especially after the engine has warmed.
Why do catalytic converters do not work effctively until the engine has warmed up?
A catalytic converter changes unburned hydrocarbons into carbon dioxide and water vapor. It's a simple chemical process, and like most chemical processes, it will either generate or absorb heat so in this case, since the catalytic converter requires heat to change the state of the hydrocarbons, it either has to be heated or it will operate quite effectively using the exhaust heat.
Note, if the engine is operating efficiently there should be very little for the catalytic converter to do.
What would cause loss of power when accelerating?
Loss of power when accelerating can be caused by a number of things. A leak in the fuel line or even a bad alternator can cause this.
Why does a crankshaft sensor have intermittent loss?
intermittent loss indicates you need a new sensor
What do you do if your Jeep Grand Cherokee will not start?
First check instrument panel to see if the SECURITY light is lit. If so, assume that something has triggered the anti-theft automatic motor cut-off. The easiest override is to use your key in the driver door and turn it RIGHT twice, and left once. Another contributor suggested the same procedure with the passenger door. If neither works, we tried a back-up plan and used two keys just in case...
First, we attached battery cables to insure power to the engine.. then attempted to start engine. Second person tried the key procedure on the driver door. It worked like a charm!
It's an ongoing problem with our 95 Jeep Orvis ed. ever since a professional battery outlet installed our new remote battery BACKWARDS and fried our electrical system. Always be very careful with those remotes. As for the non-start, if it's not the security cut-off, there are tons of other regular items to check, which I'll leave to others. Cheers!
The service engine light finally came on and it identified the Mass Air flow sensor is bad.
Why would your engine race while in neutral?
Another Answer: The "AIS" (Automatic Idle control) is a step motor controlling a valve that bypasses the throttle valve or Throttle Body butterfly. At some point in time, the valve starts to fail and do not work properly, causing erratic or high idle speeds. Sometimes it can be cleaned, but frequently signals a worn mechanism and it is better to replace it, it should not be expensive. But check that one before purchasing the replacement.
Why wont your 1985 Cavalier stay started?
The first thing that I would do is start the car and if you have time, diconnect the positive battery cable. If the car dies then it's the alt. Otherwise could be a fuel pump or possibly maybe in the trans. I had a similar problem in my 86 and it was the TCC, (torque converter clutch), which would not let my car idle right, and kill it. Hope this helps.
TCC is going bad needs to replace, but a quick fix is to unplug it from the Trans and see if the problem still occurs, if not, changing the tcc is highly recommended. thanks.
What causes a battery drain in a 1978 kz kawasaki 650?
I can be countless things, but a short is likely if the systems check out otherwise (charging, battery, etc.). To diagnose, you can check the drain on each circuit via the fuse box using a multimeter which can be had for about $10 at radio shack etc.. Buy one, learn to use it (5 minutes max, instructions included). Check charging, battery, then after, if thats all fine, pull fuses and check each circuit, based on fuse ratings, useage indicated by meters, and switching circuit devices on and off. If your battery is old and has gone dead, been stored on the ground, been through cold winters, it's likely just not holding a charge is all. Oh, if battery connections are dirty, the charging system wont be able to refeed the battery. Easy stuff, just gotta start, keep swinging til you figure it out.
What can cause my car to start and then cut off?
well it could be many things first i would look at the fuel pump if u hear it kick on the i would say ur not getting any fire from ur coil or to ur coil
What does the green key symbol on Honda civic dashboard mean?
The green key symbol, on your Honda Civic, is a reference that all systems have been checked and are functioning properly. The symbol should only stay illuminated for 30 seconds.
