Having changed temp sensor and fuel temp sensor,and cleaned MAF I am still plagued with a stall at idle and possible no start when ambient air is above 75. I pull these codes P1179,P1177,P1448 0308 1316 and 1313. The 1448 is listed in the GEMS for the Morgan but no info for the Rover. I live in Mackinaw City (Northern MIchigan) so help is pretty much out of the question.Any suggestions??

Do you not have spark or fuel when this happens?
1177 is a max.negative FMFR correction fault
1179 is a Max.negative AMFR correction fault
1448 is a evap purge valve flow 2
308 is a numbere 8 misfire
1316 is an excessive misfire emission fault
1313 is a misfire cat damage, bank A

You are in trouble, how many miles on the truck, when was the last tune related work done?

About 120,000 on the odometer...tune related work is about 2 years ago, no one in my area will touch it, I respect that.
After cooling, that is engine temp drops below running temp she will start up. And runs rich. It seems to level out when the exhaust heats up the O2 sensors so I am suspect that at least the left bank upstream O2 is shot. I have restricted abilities to get them out (the O2 sensors) What is the trick??!! I have seen the tool from Landrover but I am hoping someone might have a workaround; the tool which is scarce(haven''t seen one yet) and/or really expensive is out of my reach.
The most recent event left me with no restart and was towed, how embarrassing!
Ambient temp was in the 80''s. And I have not yet checked spark/fuel. Will do that later today. Thanks for the quick response
