Discovery V8 LPG Issues

Remove the flexi duct from the afm to the throttle body and check its operation, closed to 90 degrees when the accelerator is depressed. It just seems strange that you have low air flow resulting in a rich mixture and it not being the maf. It makes me think a physical restriction is blocking the intake air flow. So I'd be checking the whole route from air box / filter downstream. Tbh i dont think there is much else you can do if you have no spannering skills but get help. It will be something simple.
Did you get the link i put in your other thread?
 
Aside from the low air temp fault, i suppose the rest of the faults could be from a high reading from the throttle position sensor, therefore dumping more fuel in and the exhaust sniffing a rich mixture.
I just dont know enough about thor efi (hotwire efi tps can be checked with a multimeter and adjusted) and dont have access to the rave workshop manual.
 
Hello all and thanks for your comments it's been a while firstly thank you to @listerdiesel i have changed the MAF and at first there was no difference if anything worse the next day however and after a few starts the car runs much better no more stalling and genuinely pleasant! Now though I'm having a tough time as the car is very sluggish and lacks in power I'm thinking of buying new plugs and leads would this solve my issues ? Thanks Jonathan
