Vehicle
2006 Ram 1500 4.7

I got a random/multiple misfire code one day so i decided to do a tune up. (Above mentioned thread) Had some issues but it all worked out.

After i finished the tune up, I now have 7 error codes and im not sure how.
Let me say i know very little when it comes to using code readers. Im struggling to figure out my next move to get this truck right.

Attached are photos of the code reader.Codes include the following (I am new to using code readers FYI- i have OBDII/EOBD from walmart)

1/7: P0300 $07E8 Random/Multiple Cylinder Misfire

2/7: P0308 $07E8 Cylinder 8 Misfire

3/7: P2323 $07E8 Ignition coil H Secondary Circuit

4/7: P0113 $07E8 Intake air temp. sensor 1 Circuit high

5/7: P0300 $07E8Pd Random/Multiple Cylinder Misfire

6/7: P0308 $07E8Pd Cylinder 8 Misfire

7/7: P2323 $07E8Pd Ignition coil H Secondary Circuit



I am fairly positive I didn't screw up installing the plugs or coils. Any help here would be nice. Please & Thank you!
