It's a cam only lq9, longtube headers with corvette o2s, SLP lid, 42lb injectors. It was tuned about a year ago and ran fine for the longest time. Then about a month or so ago it started becoming increasingly rich. I believe that the injectors were used, but looked in decent shape. I don't have the equipment to do the data-logging. What are the easiest and simplest checks first. Injectors, vaccum leak, dirty maf?
Vac leak, exh leak, dirty maf, lazy O2's, are some checks to make. Without a scan tool, it's difficult to tell what has happened. Take it back to the tuner and have him run a scan????
