Engine light came on today. It just went off after replacing a camshaft position sensor 2 days ago. Checked the problem and I get code PO172 system too rich, Bank 1. What does that mean?

Sorry, this is on a 1997 Chevy 1/2 ton 2WD 5.7 L engine, auto transmission. Ive got around 135,000 miles on it. Despite the engine light being on, its running fine.
