I used the search and found that some later model cars had this and earlier ones didn't. I swapped a 3.5 HO out of a 2000 Intrepid into a 1999 model. The 2000 has an extra vacuum line that is connected at the cruise control connection on the drivers side rear of the engine. This is not present on the 99 car, nor is the hard line that runs to the back of the car, I'm assuming that hard line goes to the LDP pump and wiring. Does anyone know how to shut that code off, without using the LDP? Is it possible to swap in the LDP from the newer car? Other than that the swap went pretty smoothly thanks to the information on this site, I want to say thank you for that.
