SOURCE: new spark plugs gone out

If the odor is not heavy gasoline, then they appear to be oil fouled. The cheap fix is to buy at any auto parts store oil burning plugs or sleeves, these will keep the spark plugs slightly further out of the cylinder, out of the oils way, and should provide a reasonable resolution.

Check the PCV valve and hose, if they clog they will cause oil to enter engien cylinders. keep me posted

P0301 - Cylinder 1 Misfire Detected.

Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder

Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

Being you have a heavy gas smell I would look into the injectors. If injector #1 is over producing it can cause a misfire. Test your compression and fuel pressure.

When cold the engine funs fine but when it warms up it starts to miss and surges the warmer the engine gets the worst it gets till it hardly runs,dies,surges and will not accelerate.


problem indicates electronic component failure due to heat from current flow
run the fault codes to determine the area or sensor that has failed
could be a cam/crank position sensor , ignition control module , coil,even the ECM

Where is the remote start fuse located?


Do your power door locks work ? There is no fuse for just the remote start !
Remote vehicle start (RVS) begins as an RF message received by the remote control door lock receiver (RCDLR) from a keyless entry transmitter. The RVS request is sent by the RCDLR to the body control module (BCM) via serial data. The BCM monitors system conditions such as content theft deterrent (CTD), hood ajar status, and body DTCs to determine if an RVS even will occur. If conditions are determined to be acceptable, the RVS message is sent to the engine control module (ECM). The ECM monitors system conditions such as engine control parameters and vehicle theft deterrent (VTD) to determine if engine starting will be allowed. If conditions are acceptable, the ECM will initiate engine starting. During the engine run time in a RVS attempt, before the operator enters the vehicle, the ECM may discontinue engine operation if system conditions require it or a message is received from the BCM requesting the engine be turned OFF.
The RVS system will not operate if any of the following conditions are present:
?€¢
A current vehicle DTC that illuminates the malfunction indicator lamp (MIL)


?€¢
The vehicle is in valet mode.


?€¢
More than 2 remote starts have been attempted.


?€¢
The hazard switch is in the ON position.


?€¢
A current hazard switch DTC is set.


?€¢
The vehicle hood is ajar.


?€¢
A current hood ajar DTC is set.


?€¢
The CTD system detects an alarm trigger.


?€¢
Excessive engine RPM


?€¢
Excessive coolant temperature


?€¢
Accelerator pedal position greater than 0 percent


?€¢
Vehicle not in Park


?€¢
Vehicle theft deterrent malfunction


?€¢
A current automatic transmission shift lock control system DRC is set.


?€¢
A vehicle speed sensor signal is detected by the ECM.

Ok, i have a 2000 sierra 5.3 slt got the p0101 code it wouldnt star up unles i give it some gas and it shots off so, rough idle and wont stay on, i change the MAF sensor (new delphi) but still doing the...


The Mass Air Flow (MAF) sensor is located in the stream of intake air and measures this intake flow rate by measuring a part of the entire intake flow. It is what they call a hot film and is supplied with electric current from the Engine Control Module (ECM).
The temperature of the hot film is controlled by the ECM to a certain extent. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change.
The OBDII people suggest that before you replace the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with compressed air or by using a cleaner on the mass air flow sensor. Truly, all that may be wrong is a build-up of dirt.Unfortunately, in your case, replacing the Mass Air Flow did not work.After replacement, did you reset the code and drive the vehicle?.
I suggest you replace the air filter and check for intake air leaks.YouTube has some good videos on how to do this, one by Eric the car guy and one by Scottie Kilmer https://www.youtube.com/watch?v=9CPqbaSgcokhttps://www.youtube.com/watch?v=zMok2y05jNE

My 2006 Hyundai sonata reading on a code reader P2118, P2119, P2110


P2118 - Electronic Throttle Control(ETC) system is made of the components throttle body, Throttle Position Sensor(TPS)1&2 and Accelerator Position Sensor(APS) 1&2. The throttle body contains the actuator, the throttle plate and the throttle position sensor (potentiometer), which are integrated in one housing. The actuator consists of a DC motor with a two-stage gear. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. And it provides feedback to the ECM to control the throttle motor in order to control the throttle valve opening angle properly in response to the driving condition.

P2119 - associated

P2110 - A bulletin provides the procedure to clean the Electronic Throttle Control (ETC)
throttle body of Theta-2.0L/2.4L engine equipped vehicles. If a vehicle exhibits the
condition(s) listed below and deposits are found at the valve-to-bore interface inside the
ETC throttle body, clean the throttle body using the procedure described in this bulletin.

This throttle body cleaning procedure should be performed when diagnosing
the conditions listed below. Do not replace the throttle body prior to performing
this procedure.

Any of the following conditions may be caused by throttle body deposits:
• No start (due to throttle valve stuck closed or air flow signifcantly restricted)
• Rough idle or fluctuating engine speed at idle (due to air flow restriction)
• MIL "On" with DTC P2118 or P2119 occurring along with P2110:
• P2118: Throttle Actuator Control Motor Current Range/Performance
• P2119: Throttle Actuator Control Throttle Body Range/Performance
• P2110: Throttle Actuator Control System-Forced Limited Power

It seems CLEAR you have a STICKING butterfly plate in the throttle body.

I have p044 code for Camry 2004


P0044 - HO2S Heater Control Circuit High (Bank 1 Sensor 3)

The P0044 is set when the ECM detects an excessively high voltage through the heated oxygen sensor heater circuit

Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).

In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 3 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 3 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 3 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 3 circuit fuse
- Faulty Engine Control Module (ECM)

The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.

1995 hyundai sonata turns over but will not start


sounds like a crank position sensor. Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDI/II (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there.
