A very common for these problems is a leaking fuel pressure regulator. This leaks gas and causes extended crank times, stalling, and check engine light.

1999 daewoo nubira (RPM)


Hi,

Based on your description, could be anything:
  • throttle control (including A/C compensator);
  • auto choke;
  • engine management;
  • auto cruise (if your model has one)
A couple of clarifying questions:
  1. What is your standard set idling RPM, 1000? with or without A/C?
  2. Automatic or conventional/manual trnasmission?
  3. When was the last major tune-up? What parts were replaced?
  4. Does it sound like misfiring also?
  5. Any other indicators, hard starting, long warmup, stalling, excessive gas consumption, smarting to the eyes exhaust fumes?
  6. Does your battery light lits up?
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

The car dies at stop and idles rough at low rpm


OBD Tools 365 Days Shop
A rough engine idle can come from a variety of causes. During the winter months, cars may have a harder time starting and will shake when first turned on. This form of rough idle can easily be mistaken for other problems. Engine idle problems can also be attributed to malfunctioning components, such as spark plugs. Holes in the air intake valve can also cause a rough engine idle because of excessive amounts of air being drawn in.
The rough idle of an engine can signify a power loss in the car. This loss of power could lead to other problems, such as excessive gas consumption. This lack of power can also lead to additional wear on other parts of the car. Ignoring problems with the engine of can lead to a massive breakdown that will require you either to make costly repairs or replace the car entirely.

I have a misfire on cylinder 4.


It sounds like your car is having intermittent misfires as it is only happening under load. This is really hard to diagnose based on a description.
You could be getting a bad air/fuel mixture, bad wiring, bad rings, oil or coolant leak into the engine, etc...
Scan the car with an OBD tool to see what the code is as that will help narrow down the cause.

Volvo s40 1.8 gdi excessive fuel consumption


You're going to have to figure out what's causing the misfire. The car is almost 10 years old, so change the plugs to start with. If you still have a misfire, go to auto zone and have them pull the codes to find out which cylinder is the issue. Then figure out fuel or spark? Coil or injector? Was there a lean code? Check for a vacuum leak. Change the fuel filter and air filter for maintanence. The cruise control may be another issue.
