Hey everyone!

My name is Frank and I am new to CCF, I purchased my corvette in November it’s a 2005 z51 with 38,800 Km, Im based in Toronto and my car is showing me 4 error codes on my scanner.

P0174-00 fueltrim system Lean Bank 2
P0430-00 catalyst system low efficiency bank 2
P0420-00 catalyst system low efficiency
P01710-00 fuel trim system lean

The car has some modifications take I can see like
- Blackwing SLP Air Intake
- Full Corsa Exhaust System

This is my first corvette and I want to continue to give this vehicle the proper care and love it deserves. I Hope someone has encountered these codes before and can give me some advice or knowledge on how to correct this

Has your car been given a new tune or is it still running the stock tune?? If you are still running the stock tune, IMO, you need to go somewhere to put it on the dyno and get a proper tune.

I’m sure it would have been tuned at one point but I’m not 100% sure, thank you for the information I’ll contact a shop that specializes in corvettes ! :)

Welcome to the forum. First I would start by checking for a vacuum leak, it could cause the issue but the tune would be my second possible issue. ùa dirty mass airflow can also put you in trouble by sending erratic informations.
