I have a 2003 Lincoln LS V6 I just purchased from auction with 73,000 miles. Upon arrival the vehicle will not accelerate at all when the gas pedal is pressed. The service ((P)) light comes on then it says to Apply ((P)). I ran a code reader on the vehicle and the following codes popped up. P1406, P2104, P2111, P1405. Once again when the vehicle is turned on there is no acceleration when the gas pedal is pressed. It just idles.

We tried to clean the MAF sensor, We also tried to checked the throttle body positioning sensor, and cleaned the throttle body.
Hello and welcome to Just Answer. My name is James.
Basically the computer is forcing limited throttle (idle only) because it is sensing a throttle position that is out of specification. The P1405-6 codes indicate that the DPFE hoses may be disconnected. Let's start with the 2 throttle position codes as there is a chance the other 2 will correct themselves.

With the engine off, disconnect the black intake tubing from the air filter to the engine. Then remove the 4 bolts and the throttle body.
