good afternoon everyone
Is there someone that can help me with a little problem I have with my p38 ym 2000 v8 lt
I had trouble starting and it stalled , plugged in my Hawkeye and the following codes came up- p0102 / p0174 /p0171/p0172/p0175 the first code is the maff censer which I replaced car running well but I am still getting fault codes p0174 and p0171 is this anything to worry about as it is running ok but I would like to rectify if it’s within my ability
Thanks in advance for any help

I haqve a GEMS V8, not the THOR, but the codes are both to do with vacuum leaks and running lean according to Google.
Have you checked you've not got an air leak around the MAF? Make sure the large O ring for the MAF is seated correctly, and that all the rest is nice and tight.

Thanks for the reply I have not looked for a leak that’s very interesting I have thought it might be a leak but didn’t think it would be there I shall look in the morning thanks I shall let you know how I get on
 
Also check O2 sensors and wiring thereto
Thanks I have fitted two new ones about 5-6 years ago they were Bosch ones so I wouldn’t have thought the CO censors were shot but when I can get over the pit I shall look at the wires anything could have pulled them or even heat could damage them
Thanks for your idea
