Hi all,

A couple weeks ago i bought an 06 Ram 1500 4.7v8 w 88,000 miles on it. On the way home i discovered it was low oon coolant. After i topped it off and burped the system of air the truck ran great. Drove it about 80 miles and parked it. The next day i got a check engine light. Two Codes and they were:
P0300 $07E8 Random/Multiple Cylinder Misfire
P0300 $07E8Pd Random/Multiple Cylinder Misfire


I thought doing sparkplugs & ignition coils would solve this. While replaceing the plugs, one broke (#2 cylinder). All the plugs were very corroded. After about a week of putting penitrating oil on it 1-2x a day. i got the broken plug out with a square EZOut. I then finished changing the plugs and installed new ignition coils. When i started the truck after the tune up i got the following codes.
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
(See attached pdf for photos of code reader)

I'm not really sure where to start with trouble shooting this. I dont have alot of experiance using code readers. I just had a baby so i have very little time to reasearch this. This is also my first dodge. Any advice / assistance here would be great.

Clear the codes first, then fire it up and see if the codes return.

What's all the codes with the dollar signs within them?
The po113 could be something forgotten about being plugged in.
The coil failure H could be the same or else a defective one

Yes, Dodge trucker is right. The PO113 code is the plug sencer for the air duct. I took mine off to check the sparkplugs and then fired up my truck with that sencer unplug and it threw that code. Easy fix. As for ur other codes I'm not sure. U have to look them up. Hope that helps u.
