I ran my codes this morning and I got back a code 522 on the engine off test and on the engine running test I got back a code 411. What do these codes mean? How do I fix the issue or what needs replaced? The reason I ran the codes is over the last week it has developed a miss a vary mild one that only occurs a 1 or 2 miss intervals ever 10-15 seconds but the miss happens more often as the engine is given gas.... It also has some slight hesitation. It has new distributor cap new plug wires plugs or filter and fuel filter all replace less than 1200 miles ago... Can't track it down hope the codes I received can me find the issue!

Also it's 94 f150 XL 300 I6 5speed manual!

Thanks!

 

My other book would tell what the 522 is, but I'm away from it. 411 is cannot control RPM during KOER low RPM check. Check the TPS and the IAC.
