    check map sensor and engine coolant sensor. Both can cause this.

Several things can cause this but I would pay close attention to the E/C parameters using a hand held scanner.I would pay close attention to the MAF MAP TEMP TPS and O2 signals the computer is recieving from all the critical outboard sensors providing you are running on all cylinders properly which means all cylinders are pumping up properly and spark is provided at each cylinder.A dead miss can cause an uncontrollable rich mixture.High fuel pressure can cause an uncontrollable rich mixture and obviously faulty injectors which should have about 25 ohms of resistance in the injector winding.Fuel with over 10% alcohol can littlerly melt the electrical windings inside the injector causing fault.Finally I would also inspect EGR which can stick and create the E/C to add fuel to a diluted mixture created from too much EGR (exhaust gas) fed back into the air/fuel mixture....good luck

Seems that the fuel pressure regulator is bad, place a vise on the fuel return hose and if the car runs well replace the pressure regulator.

SOURCE: 2001 Nissan Maxima- runs rough, stalls when idle

Timing belt could have skipped a tooth.

Horrible vacuum leak could have started. Listen for suction noises when you raise the hood.

Someone could have poured sugar in your tank.

You could have put diesel in your tank instead of gas.

Could be a bad MAP sensor, TPS sensor, etc.

Need more details to be precise.

SOURCE: Idles okay, runs rough when gas applied

Either a bad MAP sensor, or TPS. What is the code for the check engine light? This will most likely tell you what it is.

88 f150 351w forever to start and when it does it runs real rough until I hold gas down for a minute then idle rough but will start right back up unless it sits awhile doesnt want to start back up


There are several possibilities for this problem. A "cold start" sequence is suppose to activate based on water temperature and the signal from the water temperature sensor. This makes the fuel rich and adjusts timing to make the engine run better when cold. It works like a choke only it is electronic.

There may be 2 sensors with one making the dash gauges work and the other doing the engine controls. If not 2, then 1 sensor would do the whole job.

Another possibility is an air leak in the fuel system which makes the system bleed dry overnight. It is far less common on gas engines but happens a lot on diesels.

Some earlier Ford engines from 1984 to I don't know when they stopped on trucks, would use a step-up solenoid on the accelerator bracket that worked off water temperature. Sometimes a bad water thermostat would make the temperature controls malfunction the other way (High idle, clicking, low idle) that would stall and engine as the temperature vary.

Stalls after start up, Stalls when braking, then runs fine after a few minutes


Check the ECU engine temperature sensor. If it thinks the engine is hot, it will struggle to run when cold.

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?

Stalls sometimes when stopped at lights engine misses at stop


Engine 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

My 04 Kia Optima will start but then it runs rough. It acts like I might have trash or water in my fuel line. Does anyone know where the fuel line filter is located, also could this be a problem with fuel...


Put a can of a product called "Seafoam" in the gas tank. Also do the following procedure.

Here are some of the causes 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.

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".

My 1998 Olds 88 has been stalling and running rough.


Check and clean the IAC valve. Idle Control Valve. Use brake cleaner or carburater cleaner . Remove the duct work from the air filter assembly. It is located just inside . Run the engine at 1200 rpms and spray the valve. The valve can also be removed and cleaned.
