I hava a 98 Expedition 5.4l V-8 with 165,000mi. Lately it seems to be losing low end power. I have been told this could be cured by replacing or upgrading the fuel injectors. What are the pros and cons of upgrading the injectors if possible, and wher would I find them? Thanks.

 

The pros far outweigh the cons - the cons being the work/difficulty involved in changing them. As for where to purchase them, I bought all 8 a couple of years ago for around $250-$300 from fiveomotorsport.com. Excellent quality.
