Just change the pcm on the car also new alternator the car battery light is on also its a new battery battery light on on the dash the car starters an stays on for few minutes then it turns off by itself. when i take the spark plugs 2 and 4 is okk but 6th spark plug very wet with gas and muffler blows gas black/white color smoke please someone help me out with this
thanks hudo
I would take a look at the plugs and see if they are fouled. You might have a bad fuel pressure regulator. Also, the control module or pick up coil could be bad.

First set park brake,locate PCM in van ...Compare new PCM with old to be sure new one is correct part..You will small tube of dielectric lube..WEAR SAFETY GLASSES..,Disconnect negative battery cable...wipe and blow dust/contamination from around wiring harness plugs...Remove plugs from PCM...,Remove old PCM..lightly lube connecter pins with cotton swab..,plug in wiring harness connectors..re-connect battery cable...Complete..............BROOKS..
Hi there: P0206 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.
The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.
The causes of a P0206 engine light code could be any of the following: - Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes - Open in the wiring to the injector - Short in the wiring to the injector - Bad PCM
First, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector.
Check for voltage at the fuel injector connector. It should have 10 volts or more. Visually check the connector for damage or broken wires. Visually check the injector for damage.
If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate Replace the injector
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

P0113 - Intake Air Temperature Circuit High Input The Powertrain Control Module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.
There will likely be no symptoms other than illumination of the Malfunction Indicator Lamp (MIL - Check Engine Light / Service Engine Soon).
A code P0113 may mean that one or more of the following has happened: Internally failed IAT sensor Faulty connection at IAT sensor Open in IAT ground circuit or signal circuit Short to voltage in IAT signal circuit or reference circuit IAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.) Faulty PCM (less likely but not impossible)
P0123 Code - Throttle Position Sensor/Switch A Circuit High Input A P0123 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too high a voltage. Some symptoms may include: Rough idle High idle Surging other symptoms may also be present
A code P0123 may mean that one or more of the following has happened: TPS not mounted securely TPS circuit short to ground or another wire Faulty TPS Damaged computer (PCM)
P0206 - Cylinder 6 Injector Circuit Malfunction This means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.
The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.
The causes of a P0206 engine light code could be any of the following: Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes Open in the wiring to the injector Short in the wiring to the injector Bad PCM

Hello.. looks like you are getting good fuel delivery. Is the fuel curve mixture on the scanner in specs? How is the timing, the timing chains on these engines will stretch and throw the timing off causing a ping and missfire -- a weak valve spring is something to consider. Also, the PCM may be faulty. I hope this helps.
The symptoms for this code (both) will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated. The causes of a P0206 engine light code could be any of the following: * Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes * Open in the wiring to the injector * Short in the wiring to the injector * Bad PCM
Your possible solutions, first, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector. * Check for voltage at the fuel injector connector. It should have 10 volts or more. * Visually check the connector for damage or broken wires. * Visually check the injector for damage.
Also, if you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate * Replace the injector
