A cheap and easy thing to try is to clean the carbs. get some carb cleaner and run through your next tank of gas. Also a batch of bad gas can cause the problem too.

99 dodge intrepid stalls and rough idle. When I floor it the car will fall on its face. Hesitation after I come to a stop. Shakes and idles very rough, battery is also dying often. Replaced the cam and...


Check fuel pressure. Air filter could be really clogged, usually they will collapse first. Then check for exhaust pressure out of the tail pipe. Little pressure or it's really hot. The catalytic converter/s are plugged up.

Idles roughly, then low when stopped or in park, then dies. Decreasing gas mileage. Slow to accelerate


Sometimes that's caused by a vacuum leak near the manifold area.

Sometimes air in the coolant will cause an idle problem. Air will keep the air temp sensor from sending proper info.
Hope this helps.

My 97 intrepid will start up, but putter out within seconds


Map Sensor or Crank Sensor. If you have a code reader the map sensor should throw a code, the crank sensor most often will not. Both will cause the car to start, idle to around 1,000 R's and then die.

2001 audi allroad puttering, then dying when give it gas.


Sounds like dirt made it's way to the fuel pick up from sitting on an angle. You can try removing the sender through the rear seat to detect a clog and or the fuel filter underneath. Honestly..... have it towed to reputable repair shop or dealer for evaluation.
