Per your description, it sounds like you have a vacuum leak.
Check all vacuum hoses at the engine, make sure no hoses are disconnected, cracked or damaged.
Disconnect each hose at the source on the engine and see if the engine idle stabilizes.
Let me know what you find and we can go from there.
Regards.

My checkengine keeps coming on the code is p507


If the engine is running rough at idle (although idle speed is normal), then you might have a vacuum leak. This results in a lean air/fuel mix condition and the ECU might over-compensate by trying to "richen" the air/fuel ratio.

Vacuum leaks are unpredictable and not always easy to locate; sometimes you pop the hood open and it's right there staring at you --- a cracked or disconnected vacuum line! Reconnect and it's good to go. The check engine light will turn off after you complete a drive cycle.

If the idle speed is too low or jumping up and down, your IAC (Idle Air Control) motor may be malfunctioning and in need of replacement.


Hope this helps.


Have a Great day !!!

My 2005 altima idles high and engine code


This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set.

2002 Buick Lesabre codes P0131, P0171, and P1133.


Sounds like you just need to replace the one or two 02 sensors on bank 1.If you have over 100,000 miles the 02 sensos are realy to be replaced just as spark plugs and air filteres. If you wait to long to replace them you take a chance of them not comming out and then when they do go bad you will need to replace the exhaust as well.Hope this helps and good luck.

The engine races and the temp drops. I asked the question yesterday and was told to check the idle air control. There is not one on my model. anyone?


I'm assuming that you have idle high in the engine, and IAC fault code.

DIAGNOSTIC TROUBLE CODE (DTC) 0505 IDLE AIR CONTROL VALVE (IACV) CIRCUIT FAULT

Know Your Circuit:
* In order to regulate the air entering into the engine, the Engine Control Module (ECM) uses an Idle Air Control (IAC) Valve.
* To raise the idle rpm, the ECM handles the pintle inside the IAC valve away from the throttle body seat.
* This enables additional air to bypass through the throttle blade.
* To lower the rpm the ECM controls the pintle towards the throttle body seat.
* This successfully reduces the amount of air bypassing the throttle blade.
* A scan tool will note the IAC valve pintle position.
* The greater the count, the greater air is allowed to bypass the throttle blade.
* This DTC ensures whether a low idle condition exists as defined as 100 rpm below the desired idle rpm.

Pre -requisites For Setting the DTC:
· No intrusive tests are active.
· DTC(s) P0106, P0107, P0108, P0112, P0113, P0117, P0118, P0122, P0123, P0131, P0132, P0133, P1133, P1134, P0171, P1171, P0172, P0201, P0202, P0203, P0204, P0300, P0336, P0337, P0341, P0342, P0351, P0352, P0402, P0404, P1404, P0405, P0406, P0443, and P0502 are not set.
· Engine is running > 60 seconds.
· Barometric Pressure (BARO) is > 72 k Pa (10.4 psi).
· Engine Coolant Temperature (ECT) is > 60°C (140°F).
· Ignition voltage ranges between 11 and 16 volts.
· The Intake Air Temperature (IAT) is > -20°C (-4°F).
· Manifold Absolute Pressure is less than 60 k Pa (8.7 psi).
· IAC valve is fully opened.
· All of the above must be met for more than 5 seconds.

Diagnostic Tools:
* Probe the IAC valve electrical connection for proper mating.
* Examine the wiring harness for damage.
* See whether the throttle stop screw shows signs of distortion.
* Also inspect the throttle linkage for signs of binding or excessive wear and tear.
* The following conditions may be created by a slow or unsteady idle:

1) Fuel system very high or low.
2) Foreign material in the throttle body or in the induction system bore
3) A leaking or restricted intake manifold.
4) Excessive engine overloading. Check for seized pulleys, pumps, or motors on the accessory drive
5) Excess engine oil.

The car wont start it tries but no luck the code is p1133


Trouble Code: P1133 (3.4L V6 VIN E Auto)
HO2S-11 (Bank 1 Sensor 1) Insufficient Switching Print this code dataprint_icon_codes.gif Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
DTC P0105-P0108, P0112-P0118, P0122, P0123, P0171, P0201-P0204, P0300-P0304, P0335, P0440-P0446, P0506, P0507, P0601, P0602 and P1441 are not set, engine speed from 1600-2450, ECT sensor over 158ºF, TP angle from 9-18%, Purge command over 36%, Purge Learn Memory over 0.86, fuel level over 10%, and the PCM detected the HO2S signal voltage switched from rich-lean or lean-rich less than 20 times in a 100 ms monitoring period.

Possible Causes:
  • Air leaks present in the exhaust manifold or the exhaust pipes
  • Fuel pressure is too high (i.e., causing a rich air fuel mixture)
  • HO2S may be contaminated (due to improper fuel or silicone)
  • HO2S signal high or low reference circuit has high resistance
  • HO2S heater element has failed, or the heater circuit is open
  • PCM has failed

Your O2 sensor is starting to go bad .recomend replacement before it gets worse

Codes 1133-0131-0171-0300


p1133 - o2 sensor, Insufficiant Switching, Bank 1 Sensor 1.
p0131 - o2 sensor circuit, low voltage, bank 1 sensor 1
p0171 - Lean condition, Bank 1
p0300 - Random Misfire

I would be looking at the front passenger side oxygen sensor for issues. It may be bad, it may not be plugged in, bad wiring at harness.

The random misfire may be symptomatic of the o2 sensor problem.
