I would take a look at the idle air control valve and see if it is sticking. You could try taking it off and cleaning it. If that seems to make a difference then I would replace it with a new one just to be sure.

97 chevy 1500 sputters at idle in gear can feel it a little while driving no cat. past 2 years run bank1 lean code plugs clean HELP


If the engine is misfiring the check engine light would be on and blinking and the engine control module (PCM) would store a fault code or codes for the cylinders that are misfiring. A lean code will not cause a misfire unless the engine has a vacuum leak most often at the intake manifold gaskets. A misfire code looks like this:

P0300-P0306 for 6 cylinder and P0300-P0308 for a V8.
P0300 indicated a random engine misfire, this can be caused by all kinds of issues.

My freestar engine light is on OBD says PO171 what should be replaced


I believe this can be a bad O2 sensor error. It is a lean reading on bank 1. Also what can happen are intake manifold leaks, and stuck Intake manifold runners on 1 side of the engine. For the Manifold runners, these work like a gating system. Some Intake manifolds have 2 chambers, a low and high flow. When the gating runner sticks in the high flow position, too much air enters the engine on Bank 1 during idle or low rpm.
Manifold leaks. Use a spray water bottle and with the engine running, spray the seams of the manifold. A leak will change rpm or stall the engine.
Hope this helps you.

Engine light on po106 code


  • OBD II P0106

Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Powertrain Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor P0106 code is set when there is a problematic or erratic performance in the voltage signal to the PCM.

Symptoms

  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • In some cases, noticeably poor engine performance may occur

Common Problems That Trigger the P0106 Code

  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  • Intake Manifold vacuum leaks
  • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections

Common Misdiagnoses

  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

Hi,

I'm Ben and -- hopefully -- I can provide some meaningful assistance.

In my opinion, the problem lies with you P0174 reading. I'll explain.

OBD II Fault Code

OBD II P0171
OBD II P0174

Fault Code Definition

OBD II P0171 Fuel System Too Lean (Bank 1)
OBD II P0174 Fuel System Too Lean (Bank 2)

Symptoms

  1. Check Engine Light will illuminate
  2. In some cases, no adverse conditions may be noticed by the driver
  3. In other cases, there may be performance problems, such as a lack of power on acceleration and some "coughing" or misfiring
  4. The vehicle may have trouble idling, especially when warm or when sitting at a stoplight

Common Problems That Trigger the P0171 and P0174 Code

  • PCM software needs to be updated
  • Vacuum leaks (Intake Manifold Gaskets, vacuum hoses, PCV hoses, etc.)
  • Mass Airflow Sensor (MAF)
  • Plugged Fuel Filter or weak Fuel Pump
  • Plugged or dirty Fuel Injectors

Hi 2005 ford freestar engine light is on bought code scanner and was given these codes....p2195, p2196, p0053, p0132 and p0133 i also bought the shop service manual from the dealer..however, ididnt...


p2195 is 02 sensor stuck lean ( bank 1 sensor 1 )--check for a possible vacuum leak in all vacuum lines.-- if no vacuum or other leaks could be egr valve. p2196 is the same but stuck rich,--p0053 is ho2 sensor bank 1 sensor 1 heater resister all codes are related to the o2 sensor, p0113 is intake air tempurature curcuit high input ( IAT ). check wiring or senser replace if need be. if you can not find any leaks and egr system is ok, then its the 02 sensor causeing this.

Rough idle vibrates and po171 code service engine soon. jamesrowland9@aol.com


Hi, a Ford P0171 is a LEAN code for cylinder bank 1, and P0174 is a LEAN code for cylinder bank 2. These codes commonly occur on many Ford vehicles, and are set when the powertrain control module (PCM) sees the air/fuel mixture is running too lean (too much air, not enough fuel).
When the Check Engine Light comes on, either one of these codes, or both, may be found when a code reader or scan tool is plugged into the vehicle diagnostic connector. IF the vehicle is driven long enough, typically both codes will be set.
A P0171 lean code for bank 1 is the cylinder bank on the RIGHT (passenger) side of the engine on Ford vehicles with a V6 or V8 engine and rear-wheel drive.


A lean fuel condition may exist if the engine is sucking in too much air and/or the fuel system is not delivering enough fuel. If bad enough, a lean fuel condition may cause lean misfire, a rough idle, hesitation or stumble when accelerating, and/or poor engine performance.
Unmetered air can enter the engine through a vacuum leak, a dirty airflow sensor that is not reading airflow accurately, an EGR valve is not closing and is leaking exhaust into the intake manifold, an EGR valve that is allowing too much flow (because the EGR differential pressure sensor that monitors EGR flow is faulty and is under-reporting EGR flow).
If the problem is not enough fuel, the underling cause may be a weak fuel pump, restricted fuel filter, leaky fuel pressure regulator or dirty fuel injectors.
