I have a bit of a problem. Apparently a few sensors went up in my '94 F-150 XL 4.9(Straight 6), the codes it gave were O2 sensor(replaced) MAP sensor(replaced) and the Knock Sensor. Every single autoparts store around here does not even carry a Knock sensor for my truck, and when I searched online the only thing I could find were Knock sensors for 5.0 liter engines. Do straight-six engines even use Knock Sensors?

the inline does have a knock sensor. it is on the block near the distributor. i checked with the dealer and they dont carry it anymore. i couldnt find any store that had one. i have had similar random codes like yours but have yet to find the problem. the only sensor i havent replaced is the knock sensor

Knock sensor???
I have a 5.0L 1996 f150. If you have spark knock it my be that the Dizzy has a problem. You should further investigate that your Dizzy is advancing correctly.
I had a faulty module in mine which was making it advance out to much but with a quality testing facility should be able to determine this with ease.
Hope this helps.
