Switched to Rotella T6 5W-30 and WIX 51515 yesterday. Truck running smooth!
Today I will switch to Champion Iridium plugs and wait for my new Wires to arrive!

I had code 300 and code 302.

#2 connector looked very rusty! will clean, put new plugs and scan for any changes. Next week is shot for Thanksgiving.

Next on my list

1. Replace wires with 8mm
2. Front Shaft rebuild or buy - have not made the decision yet
3. 3 Fricking Amigos after that - Any suggestion besides getting ABS Amigos USB?

 

I think there is a texas land rover club. You might see if any of them have one and would pull the codes for you, maybe for free, maybe for a charge.
