When i turn on my car it idles well but when i rev the motor it lags a lot and sounds like its having trouble responding. It will eventually rev up but it seems to be like one second later. I know its an electrical problem. but someone said that the ECU is having trouble sending the signal to the throttle actuator. So i might need to get a new Throttle Actuator..HELP!
What is the year make and model,you are describing a delay,some model require a ECM reflash for the solution

yoy need to change both the Air Mass Sensor and throttle valve actuator to eliminate this problem. The actuator is pretty pricey but thats the ONLY solution i'm afaraid.

try cleaning the throttle body with top end engine cleaner, if it lags you have a problem.

First, to read VW codes you will want to get yourself a $50 VAG tool. It will read all your systems, not just the ECU.
Electronic Power Control can go out for several reasons. Check your brake lights with the car running. Check you radiator fluid level. If the car is running bad, you could have bad spark plugs/ wires or ignition coil.
The traction control is tied into the ABS system and often causes problems here as well. Each wheel has a speed sensor and magnet wheel in the hub. You can check these for damage by removing the tires for access. The sensors come out by hand, and inside the hole they come out of is the place to check the magnets with a flash light. Apply a small amount of wheel bearing grease to the sensor.
The control unit goes out in these systems at an alarming rate. They can be easily removed, and repaired for under $200 at modulemaster.com
Since it is intermit, I suspect most likely a loose sensor, or electrical connector.
If your brakes feel squishy at all, bleed the brake lines of air and contaminants.
Good Luck!

I have 05 LS. I had to codes a few days ago. After doing research on line, somebody, somewhere said it was coil #4. (passenger side nearest firewall). Not throttle position sensor or throttle body. I replaced #4 and tested around the neighborhood at times with RPM over 4k. Did not go into limp home mode. Ford will replace coils free if car has under 100K. I was in a hurry and purchased coil made by Borg Warner (limited lifetime warranty) for around $60.
