Possible but more likely other sensors like MAF or O2. An advanced scanner that can check fuel trims can check those as well. Most go into an extra rich "limp mode" if one or more sensors can't register for some reason. You should get codes that narrow it down to one bank or the other if it is running extra rich and check fuel trims as well which will help you isolate, Check fuel pressure first to see if in speck could simply be a bad regulator and running to high
