MAP Sensor is Faulty and needs replacing. All the other suggestions are possible but the MAP Sensor is the Idle control for the Central Processing Unit, or CPU>.

LOW IDLE CAN BE CAUSED BY MANY THINGS.CLOGGED AIR FILTER. LOW COMPRESSION OR MISFIRE CONDITION.IDLE AIR INLET PASSAGE OR THROTTLE BORE IS DIRTY OR FULL OF DEPOSITS.IDLE AIR CONTROL VALVE FAILED.MASS AIR FLOW SENSOR COULD BE OUT OF CALIBRATION. THROTTLE PLATE THROTTLE SHAFT OR LINKAGE IS DAMAGED OR STICKING.PROBABLY HAVE REMOVE THROTTLE BODY ASSEMBLY REMOVE IDLE AIR CONTROL VALVE AND THROTTLE POSITION SENSOR.BUY CAN OF CARBURETOR OR THROTTLE BODY CLEANER SPRAY CLEAN ALL CARBON BUILT UP AROUND THROTTLE PLATES AND BORE.LET AIR DRY BUY A NEW THROTTLE BODY GASKET.

    MAP, or Manifold Absolute Pressure Sensor can depends on the usable voltage signal from other air quality/volume sensors on the engine and if it is Faulty, itself, (the MAP Sensor) it also sends its own signal of trouble to the other sensors in a faulty manner through the PCM's ECM, or engine control module, causing the engine to limp or adjust while 'Setting a Code' to the Check Engine Soon or MIL (Malfunction Indicator Lamp) if the cause of poor idle or polluted exhaust from the catalytic converter (O2 Sensor) can not be smoothed out by the Engine Control Module. This signals and allows a Code Reader to be attached to your vehicle through a digital ling under the dash which pinpoints any of the Systems and Sensors responsible for the 'TROUBLEMAKING'

Has 358000 miles, just had leaks repaired. Twice since my oil pressure gauge reads no pressure but not all the time? Why


1. Oil Pressure Gauge Not Working You will notice this happens when your oil pressure gauge is not reading, whether the engine is turned off, idle or running. Try to step on the gas to rev up the engine. If the oil pressure gauge still doesn't change its reading, your gauge is busted. It's best to replace it as soon as possible because you won't have any idea if your car is already overheating or not.
2. Oil Pressure Gauge Reading Too Low When your engine is idle, the oil pressure gauge will have a low reading. When the engine starts running or when you're already cruising or on the freeway, your gauge's reading should have increased. If it stays on a low reading, then you now your oil pressure gauge is broken.
3. Oil Pressure Gauge Reading Too High Another common oil pressure gauge problem is when your oil pressure gauge is reading too high when your engine is idle or when it's turned off. Rep

Low oil pressure indicator at low rpms (idle) '97 olds V8


Low pressure when at idle, after the engine has warmed up and the oil has thinned, indicates that the oil pump is worn and needs to be replaced.

Low idle, engine vibration


I see this is an older question, but in case someone is having the same problem, here goes.
Besides the things above, I'd pull a spark plug, check it. Could just need a tune up, or you could have just a single cracked plug. One bad plug or bad spark cable will cause what you described. I always like to start with the simplest/cheapest solution. A tune up with new cables won't hurt anyway.

1999 ISUZU RODEO IDLE HIGH AND LOW IN PARK ANY IDEAS TO FIX IT?


Hello
The engine and transmission in this cars drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL THE DIAGNOSIS & TESTING IS COMPLETED.

If you have check engine light on you need to have the Diagnostic Trouble Codes read and this will give you a clearer idea of where the problem may lie. A faulty O2 sensor could certainly lead to an over -rich mixture but here is another possibility: Faulty coolant temperature sensor...leads to ECU not being told when engine has reached operating temperature ..... ECU instructs injectors to maintain open cycle condition and keep the mix rich as if engine is still cold. So the causes of rich mixture and lumpy idle can be varied. The DT codes really help in focussing area for examination and ultimately will save time and money. Autozone do DT code reading as a service.

check to make sure catylitic convertor is not plugged. if it is ok, then put a code scanner on to read codes, may have a bad 02 sensor. if you dont have a scanner, most auto parts places will scan vehicles for free.

1988 Dodge Aries K 2.5L Engine Trouble and codes


CODE 14
Trouble Code 14 indicates that the Coolant Temperature Sensor (CTS) is reporting abnormally high readings. CTS is used to control fuel mixture, timing, idle speed, TCC and EGR operations among others. The thermistor used has a low resistance when hot, rising as the coolant cools. This error then, indicates a very low resistance in the CTS circuit.
CODE 15
Trouble Code 15 indicates that the Coolant Temperature Sensor (CTS) is reporting abnormally low readings. CTS is used to control fuel mixture, timing, idle speed, TCC and EGR operation, among others. The thermistor used has a high resistance when cold, lowering as the coolant warms. This error then, indicates a very high resistance in the CTS circuit.
CODE 33
Trouble Code 33 indicates that the Mass Air Flow (MAF) sensor is reporting more air is entering the engine than makes sense based on RPM and TPS. The MAF sensor produces a frequency output; around 30 Hz at idle to 150 Hz under acceleration. The frequency varies proportionally to airflow. The ECM monitors the frequency and thus determines airflow into the engine. Typical idle MAF is 5 to 7 grams per second.
