The reason i used the crown vic is because it was the first fi pre obdII car that i found that ran great and was cheap. i didnt matter what it was out of i would have had to make mounting brackets for any engine. i pulled every single wire / harness off the crown vic and connected them all on the 57. i wanted to make sure there were no wiring "missing signal" issues.
I have been told that the tps needs to be adj due to the extra airflow from the air filter i installed, however it is fixed on the 4.6. I have also been told that when i removed the cats it removed a certain amount of back pressure the eng needs to run correctly. I am thinking more and more that that might be the most probable reason for my problem. Has anyone ever heard of that before?
