Lots of OBD-II codes, please help decipher

[newstylecustoms]

I had an incident on my way home form work today after a short full throttle acceleration, my truck (99 Explorer 4.0 SOHC from a 2004 Ranger) died and would not start again for about three minutes. I am not very familiar with obd codes or how to best interpret them. My only tool to retrieve the codes is a ScanGuageII and the codes it pulled were the normal P0171, P0174 that I attribute to a leak in the PCV system I had to rig up while converting to the 2004 engine. The new one was a P1100 which I have read was a dirty MAF sensor, so I cleaned the sensor. The codes that I have not found any useful info on are P0421, P2417 and C0354. Apart from the today when it quit and would not restart it has run great since the swap was completed in August 2013. Any help would be much appreciated.

BTW I know that I need to changed the fuel filter but twice I have tried to removed it and cannot get the lines off, it feels like I have the springs released but they will not come off with the two tools I have, if you know of the perfect spring lock tool please let me know I have not had this problem with fuel filters before.

Thanks

Best tool I have used is the AC line lock tools that are White platic on a little rack. Like $12 bucks at Parts house.

P1100 Mass Air Flow Sensor Intermittent
P0421 Warm Up Catalyst Efficiency Below Threshold (Bank 1)
P2416 O2 Sensor Signals Swapped Bank 1 Sensor 2 / Bank 1 Sensor 3

C DTCs are chassis codes but that one looks suspicious. Are you sure you posted the actual code?

I suggest that you check the MAF sensor electrical connector. The torque reaction of the motor may have pulled the connectors loose. Also, did you check your motor mounts when you swapped the engine?

I was hoping you would reply to this thread, When I cleaned the MAF meter I disconnected the meter and reconnected it. At the same time I checked the throttle slack and found there was alot, used the zip tie method to take out some of the slack. On the first test drive after resetting the codes while driving I now noticed that at full throttle it switched to open loop and I don't remember it doing that before, I realize it is supposed to do this.

As for the C0354 code, that is what I wrote down but since I have cleared the codes I don't have access to them. I don't have the control trac transfer case anymore could this code be related to that?

I have seen those but never used one, I will have to give it a try.

P18xx

Transfer case related codes would probably be P18xx. The transfer case is part of the Powertrain. Pxxxx codes are Powertrain related. Did you install the 2004 Ranger engine wiring harness or use the stock 1999 engine wiring harness?

I used the 99 harness and intake. The CEL has not yet come back on, this may be the longest it has been off since the engine swap. I also torqued the upper to lower intake bolts each about 45 degrees more in hopes of stopping any slight vacuum leaks there. I did install new gaskets when I assembled it last summer.

CEL came back on today, codes p0171, p0174 and p1100. Seems to be running fine though. Could this mean the MAF sensor is failing? Anything else set the P1100 code?
