1 Answer

Possible causes of your issue:

  1. Clogged air filter
  2. Bad fuel pressure regulator (most likely)
  3. Sticky idle air controller (also likely)
  4. Burned or stuck EGR valve, or bad EGR solenoid
  5. Bad throttle position sensor (especially if the "Check Engine" light is on or flashing)
  6. Bad oxygen sensor (especially if the "Check Engine" light is on)
  7. Water in fuel or bad fuel
What to do:
  • Start by removing the air filter to see if the problem persists. If the air filter is dirty, replace it.
  • Next, verify that the Check Engine light is operating by turning the key ON but not starting the vehicle. The Check Engine light should be illuminated. If not, replace the Check Engine light bulb.
  • If the Check Engine light is ON when you start the car, try feathering the accelerator pedal to see if the base idle stabilizes or changes. If it does, replace the TPS (Throttle Position Sensor). This is a fairly inexpensive part.
  • If the Check Engine light is FLASHING, or ON, next you will need to have a local mechanic or your local auto parts store attach an ODB scanner to determine what error codes are present. This will help you pinpoint the issue.
  • Once you have pinpointed and corrected any issues present using the ODB codes, you will need to attach a FUEL PRESSURE GAUGE to the fuel rail test point to determine if the fuel pressure is correct. If it is too high, the FUEL PRESSURE REGULATOR has failed. Again, this is an inexpensive part but the fuel system pressure must be released before servicing this part. Best done by a qualified mechanic.
  • HAS THE CAR SAT UNUSED FOR A PROTRACTED AMOUNT OF TIME WITHOUT FUEL BEING REMOVED OR ADDED? If so, the condition you are describing may be a result of bad fuel. Modern fuels contain ethanol, which causes moisture to condense in the tank when it is not agitated. This can cause water to build up in the fuel, and causes the fuel system to rust as well as an idle issue that resembles what you are describing. Try adding new fuel, and add a full bottle of FUEL SYSTEM WATER REMOVER. Remember: IF FUEL IS ALLOWED TO SIT IN YOUR VEHICLE'S TANK (without new fuel being added) FOR MORE THAN SIX MONTHS, IT WILL GO BAD.

Stalling at low idle


I don't know this specific car. But, if it has one, check your Idle Air Valve. This can cause the engine to stall. If you can hold the gas pedal and the engine will continue to run until you let off the gas, it is likely the IAV. It will not necessarily cause the engine to run rough. That could be a number of things like spark plugs, wires or dirty injectors. It could also be a compression problem. Is the check engine light on?

What do i need to be changed it stalls when pushing on the brakes and plus the idle.


i need a little more info, 2 things could be the problem, first you could have a bad brake booster causing an extreme vacume leak which could stall the engine, or at least make it run very rough and stumble when brakes are applied, the other thing could be a low batt, when appling the brakes the brake lights will come on causing a voltage drop to the engine causing it to stall, whoever the condition would drain the batt to the point that it probably wont have enough power to restart the engine, if this is the case you would also need to check the alternator for charge rate easy enough to check hook a voltmeter to the battery with the engine running it should read at least 13.5 volts up to but not exceeding 14.9 volts

1998 1.4 PUMA RUNS FINE AND IDLES FINE REVS PROPERLY BUT THEN WONT IDLE ?


ngine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Revs up and runs rough then stalls, it runs very rough, it can barely idle, put in gear and it stalls


I would like more info on the vehicle, as to the engine size. There are vacuum leaks on this engine, both the 4cyl and 6cyl. The injector lower seals are prone to cause this condition, but to check for this and to do it safely, is have it smoke tested with the proper test equipment. The EGR valves can also stick partially open, causing a rough idle and then a idle fluctuation and a stalling problem. Another poss cause is the idle control motor is failing. This vehicle should be taken in for service at a very reputable repair shop. If not properly diag, will cost hundreds of dollars just to "PUT PARTS ON IT UNTIL IT RUNS GOOD".

Revs drop coming to standstill


Here is the cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) 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.
