I have a question ! I don't know if anybody can help me ! I'm in Plano Texas ! I don't know where to take my crossfire ! The check engine light is been on for a while I took it to a mechanic he found a leak he changed some whose ! The light is on again with code p092 my car has 2 new sensors 1 and 2 but I think there are 4 sensors !! Now the car when I'm in traffic light and the car is hot and the level of gas is half of tank or less ! The car starts shaking and a few times almost turn off ! Anybody has any idea what that could be ? I'm taking it today to a mechanic to see if they find what it's wrong with it ! Any help I could get I would appreciate it very much !

 

Have you checked the fuel filter?

 

No I haven't check that ! Now that is a bit cold weather the car is running better ! The check engine light still on, I checked the codes , and it says something about the vacuum system , which is what my mechanic it's been trying to seal it ! But when I use the car for log periods o time , it will start shaking and sometimes even turns off like is it had something caught or like if the car was coughing ! And I push the gas all the way when I'm start to take off and the car goes slow but then like coughing and then takes off really quick ! It's so weird ! I don't know what else to do !

 

These are also the symptoms of a bad MAF/IAT sensor, or a bad connection to it ......

 

What is a MAF/IAT sensor? They have already changed the oxygen sensors ! Idk if that was even necessary !!

 

I had a similar issue a few weeks ago I noticed at idle my engine would shake a bit I looked under the hood and the line from the MAF to the valve cover was falling apart. Cost me $2 to replace and runs fine now.

 

P092? I find no listing, what year is the car and how many miles on it? P0192 maybe?
There was a problem some time back and it was a charcoal filter and valve problem, there was no air or little air going into the gas tank to replace the used fuel. In another case the tank collapsed due to the vacuum.

 

What is MFA ? Where can I buy that ?

Thanks for your reply btw

 

my car did the same thing just before the crankshaft positioning sensor crapped out...

 

What is that ? Omg ! The car is been like this for like 6 months now

 

It's MAF, not MFA.
The MAF sensor is located in the plastic tube that connects to the engine cover / air filter assembly on a N/A.
MAF = MassAirFlow

Thank you very much for that info and for the pic ! Yes they sealed that part , because the mechanic said he didn't wanted to change that sensor and that he could fix it ! But I guess still licking air '. Do u know if that same part is the vacuum system something ! Because when I put the computer on my car to clear the codes it says p0175 and p0172 and I looked them up and it says something about the vacuum system passing too much air !

 

P0172 :
When Monitored and Set Condition
When Monitored: With the engine running in closed loop mode, the ambient/battery temperature above -7°C
(20°F), altitude below 2590m (8500 ft). and fuel level greater than 15%.
Set Condition: If the PCM multiplies short term compensation by long term adaptive and a certain percentage
is exceeded for two trips, the MIL illuminates and a trouble code is stored.
POSSIBLE CAUSES
EVAP PURGE SOLENOID OPERATION
O2 SIGNAL CIRCUIT
RESTRICTED FUEL SUPPLY LINE
FUEL STRAINER PLUGGED
O2 SENSOR GROUND CIRCUIT
MANIFOLD ABSOLUTE PRESSURE SENSOR OPERATION
ENGINE COOLANT TEMPERATURE SENSOR OPERATION
O2 SENSOR
ENGINE MECHANICAL PROBLEM
FUEL FILTER/PRESSURE REGULATOR
POWERTRAIN CONTROL MODULE

Oh wow ! All that ? So what's all that ? The car does run different when it gets hot ! How or what do I need to fix ? Thanks for all hour help
