i have a ford f 150 xlt 4.6 L . i have had problems with it since i bought it about 3 months ago. i have cleaned out the throttle body. that didnt work either. when i try to come to a compleat stop it wants to stall. then when i start out i have to floor it to get it to go. then it does. when i get to a ceaten speed the front end starts to shack until i let off the gas then it stops. i replaced the iac value and egr value. nothing there either. i also replaced the sock that is in my gas tank. nothing there either. i still have the same problem. please can somebody help me i am lost with my truck.
my truck also has 1997 parts on it. i was told that. so it is canada made

 

Check engine light on? Tried changing the inline fuel filter under the driver in the frame rail?

 

Well you see when you don't know much about how things work, throwing money at it makes you angry in a hurry. Happens to a lot of owners.
How well does it start?
Does it idle?
Is the CEL lamp on?
Is there an air leak between the Mass Air meter and the throttle body?
Are there any codes stored?
Is the EGR valve being held open even through the valve is not faulty?
These are some of the items that will tell you the direction to go for solving the problems.

 

my t-bird used to almost stall and i had to floor it to get it going...after i replaced the fuel filter and the distributor cap and wires it ran great. i would try the fuel filter first though.

 

I seem to recall a TSB or something about the power steering system and a valve in that system that would cause stalling while stopping and turning. Is this straight line stopping, or turning and stopping?
