1997 Ford Crown Victoria 4.6L MIL Lamp on, Spark Knock
There is only a bit of spark knock at times. It takes around 75 to 100 miles to set a code. We have changed the MAF, DPFEGR and all 4 02 sensors. We tryed putting a computer from another one of our fleet. We are out of things to try and need help.
