Help! 1st time disco owner . Random misfires.
Hello folks. So I just embarked on the land rover journey about a month ago. It's a 2003 disco2
with 146000 miles and I'm having trouble getting this thing on the road Due to a random misfire. Here is a list of codes that I am getting. Spark plugs are good, spark plug wires are good, replaced coil pack, Replaced the coolant temperature sensor, Done head gasket work, Bought the truck with the secondary air injection system deleted. Engine Runs great and seems to idle OK. Just wanting to get help on diagnosing without throwing more money at this then I have to.. I love the truck and I am looking forward to enjoying it. Decided to just get help before replacing sensors and other things because I know sometimes 1 problem came cause other codes to pop up. Also there is a black moist soot coming out of tailpipe but no smoke. It does kind of have a gas like smell. Semi burned like smell.
P1451
Po414
P1482
Po445
Po448
Po102
P1590
Po340
Po134
Po135
Po155
P1300
P1319
Po300 after short drive.
I do not live in an area where emissions testing is done also

I'm not an expert on SAI, but it only pumps air into the heads.
At the moment, you're getting fault codes for your SAI, EVAP, O2 sensors, MAF, camshaft position sensor, and coil packs.
If you don't know what's been done, it's always a good idea to start with a new MAF and O2 sensors, as they're not terribly expensive. I'd also check the work on the coil packs; make sure the connectors are both clean and firmly seated. Check the connectors to the ECU as well, and inspect it for damage.
Also, it's always good to check all your fuses. I would pay special attention to fuse 2, as it supplies power to a lot of the sensors you're having issues with.

it's not just a "miscommunication." you will always get errors unless the ecu is reprogrammed to not look for the sai equipment.
in addition, if you're in an area that requires emissions testing then (supposedly) you won't pass if the vin indicates that sai was fitted from the factory but has since been removed.
