Thanks for the info Threedogs. I had no idea until joining this forum that the 3.0L engines had such a problem and I have been reading threads endlessly trying to figure it all out. This may be a really stupid question but if the MAF sensor getting gummed up with shit is the main cause of the problem, is there a simple way to just clean this regularly to prevent the problem occuring? My thoughts are that if it were that simple then everyone would just be doing that, but I thought it best to ask this question & thought maybe you all like the sexy guages so much that it becomes "necessary". After seeing some killer custom pod setups, I'm starting to think that the expense may well be justified.
My 3.0 has done 230k and I currently can get on a highway run about 10.5kms/L & 8.5-9kms/L around town.
