You may need to go to a GM dealer. Their computers are a little more accurate than most mechanics. They are also familiar with your car and may have seen it before.

SOURCE: Engine sporadically stalls

Mr Delio I asume that your car is piece of sheet because mine has the same problem.
Pehaps going at low RPM the inyection system do not work propely due to the need of clean the inside car. Lets consider that at low RPM for a short time the inyection can be block out.
On the other hand may be could be a condenser that lost its energy for a while.
I f you need futher assistance just pay for it.

SOURCE: honda accord 1996 v6 2.7 liter,rpm gage jump up and down

Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: when braking, engine revs up and car moves forward

I have a 1997 Ford Explorer with same exact problem. Even worse, my engine revvs so forcibly, that the truck moved forward and struck another vehicles. You need to replace the oxygen sensor annually. My mechanic informed me that this problem is inherently prevalent in Fords. Hopes this helps? Dave

Need to take to a shop with a GM tech 2 or higher scan tool. These tools can actually display various sensor readings and voltages in real time and can be used while driving the car to recreate the issue. These are super expensive scan tools so most shops don't have them. Call around or bite the bullet and have a dealer do it. The money you spend on a correct diagnosis will be saved by not throwing random parts at it based on guess work.

Have a Chrysler 300c start up fine but shuts off after a minute or two what is the problem


On 9/03/15 engine light came on. The shop installed new EGR valve & cleaned fuel injector induction system, combustion system, throttle body plate & combustion chambers for $901.33! Around 02/08/2016 my car started something new! While stopped at any place with the engine in drive it would cut off! I would re-start it & put it in drive, it shuts off! I had to drive with both feet, one on the gas pedal & using the other to stop while not letting the gas peddel all the way up to keep the revs up to keep the engine running!!
I took the car back to the shop on 02/25/2016. I explained the problem the shop diagnostics said the car tge Electronic Control Unit was faulty & needed to be replaced. It was replaced For $609.96. I picked the car on 02.29/2016. Drove 3 miles, stopped at a red light & the engine shut off! I re-started it twice. Drove home using the two foot dance step! I drove it 03/01 & 03/03, 2016 the total cutoffs are now 19 total.
I think the problem is a bad (Fuel Pump Pressure regulator) & I'm not a Mechanic! I will suggest this when I take the car back to the shop. I heard that Chrysler knew something about this & set a date for recall in January 2014, but never made it known to car owners. If this true, SHAME ON YOU CHRYSLER MY NEXT CAR IS A "SKATEBOARD" THAT I CAN FIX MYSELF!!

I own a 2009 Pontiac G5 My car starts fine but the battery light stays on and it stops running within 5 minutes. Could you please give me an idea on what could be wrong and when my car does start, wou


You need a new alternator , Check your amps coming out of the back of your altenator you will find it is not sending 14 volts when its running. The reason it starts and runs for a bit after it sits or charges is that the car is running on the battery if you keep this up you will not only need a new altenator but a new battery

The check engine light should be on and when it is the engine controls are in Limp mode. That means the computer is using a pre-set list of settings to try to keep the engine running long enough to get the car to a shop.
You need to get the problem with the MAP sensor fixed and get the light turned off.

It is hard to confirm...as you are aware...your battery is draining when not running...First try turning off all power including the radio on your next shut off...If this does not work, The only drain is usually the starter has developed a short...replaced one...and fixed problem 100 %...(as long as everything else is properly shut down)...Hope this helps...nice car:)

typically your problem is in the column. That's for cars that have the shifter on the column. What's happening is the gears aren't lining up to put the shifter in the park position. Unless mechanically inclined you'll have to take into a shop.
