2003 Galant Idle Problems....
[SIZE="4"]Today i took my 2003 galant, 2.4l 4 cylinder, to walmart. Went inside for 10 minutes and when i came out, I tried starting the car. It started just fine and then turned off. It seems the car will not stay running at idle. If i keep some pressure on the gas pedal the car will run when i release the gas pedal and engine starts to idle, the car will turn off. I was low on gas, so kinda kept the engine above idle and power braked the car a little so i could drive across the parking lot the the walmart gas station. I put in a few gallons of the Super unleaded, encase maybe the nasty stuff at the bottom of the gas tank might have been causing problems. But it didn't help.
So I have pretty much determined that i am having a fuel delivery problem. But my question is how do i go about diagnosis this issue???? A full fuel pump assembly with strainer is $250, and a Idle Air Control Valve is $250, I don't want to start buying parts that don't need to be replaced. Tomorrow I am going to clean the Mass air Flow and replace the air filter but i doubt this will help anything. I did clean the Throttle Body about 6 Months ago. There is evidently no external fuel filter on this car.
Im not sure if its the fuel pump seeing how the car will start and run as long as the gas is held down alittle. Can someone please tell me how to check the fuel pump and/or the Idle Air Control Valve to find out if they are working or not???
