Default lean fuel condition

Had my 03 Z06 15,000 mile service done. They supposedly cleaned the fuel rails and I have had a lean fuel code come up twice since then. I also installed a Vararam CAI after I had it serviced. both times the code is on the left side. any ideas before I take it in to be checked?

Could be a clogged fuel filter. My work vehicle threw up a "Lean Left Bank and Lean Right Bank" codes. The shop replaced the fuel filter and no more problems after that.

I would check the fuel filter as well. You also might need a tune with the vararam.

could also be a bad 02 not switching and staying on low voltage.

make sure your vari-ram is sealed any leaks around MAF or air filter will throw lean codes, I had the same exact prob. w/my 03 z/06
