Need Advice!! Multiple misfire/emission/O2 codes
 

I own a 2000 Disco2, about a month ago i was having issues with my truck going into limp mode every time I hit a bump. So I’d pull over turn it off and back on and it would be fine. That happened a few times until the last time where instead of limp mode it just turned off. I got a tow started to do a bunch of research that led me to the xyz switch, replaced that. But still would not turn over like it wasn’t getting any power. More research, considering the recent events found out the crankshaft position switch was bad. Boom, swapped that out. Started right up like normal (mind you when I bought it it started up rather loud exhaust leak sound coming from the passenger side engine. guessing the header and it always quiets down once its warmed up) a week later it starts idling really rough and I’m burning through gas like crazy, ugh. I have autozone run a scan and these codes come up p1300,p0447,p0453,p0134,p0140,
p0141,p0161,p0305,p0307,p0303,
p0300,p1319. So far I have put new spark plugs and 7mm wires. I took off the tin house looking housing when I took off the intake manifold just out curiosity and it was caked with black residue, passenger side was clean.

please give me some ideas on what to do next, thank you!

Welcome to the forum.

Do you have an SAI system?
It helps to have a Land Rover specific diagnostic tester like a Nanocom or a Foxwell NT-510/520/530 to verify fault codes.
Check your fuse F2 in the engine bay to see it's blown. Fuse F2 controls the Engine Management System which consists of Secondary Air Injection valve for the system, purge valve, camshaft position sensor, EVAP canister, leak detection pump, all 2 or 4 O2 sensors, and MAF.

Yes I do have SAI system and fuse number 2 is good.
thank you im glad that this forum exists I would be lost with all these sensors lol

fuse2 👍🏽

Can anyone help here?

did you figure it out?
