so to conclude . we are thinking there may still be an air leak (vacuum) before the maf somewhere ?
assuming there arnt any physical engine problems fundanentaly that can cause this then this leak could be a number of (already checked too ) items.
inlet manifold -to-head.
injector manifold and injector seals to manifold.
breather seperator box,breather plastic top section,hoses and various 'o' rings associated with .
anything allowing extra air through the physical engine breathing such as rocker cover leaks.oil filler cap,dipstick etc
rings/seals on throttle body.
splits in the concertina hoses from throttle body down to front before maf.
connection to brake servo and vacuum take off to storage vessels .
thats a list which springs to mind . there may be more items ( or possibilities for the syptoms.for eg . what would a partially blocked exhaust show as ? what would a poor air filter or blockage show ?)
these are areas that i will be checking on mine too when i next do the cambelt as i have a +3% ish LTFT on mine which seems to affect nothing but i would like to reduce (most garages are telling me that within 10% is no issue anyway ) but im being told on here that it should be zero.
