Engine running issue

After replacing the AOS I recieved a check engine light. This happened about 150 miles after the replacement. The scan tool read out P0174 and P0171 and the faults were reset. Online resarch led me to believe that there might be an air leak. I checked my work ond found two hoses that were not fully engaged. After fixing them, I started the car and it would not run. If I gave some gas it would run but was very rough and backfired. No check engine light. Thinking it may be a failed MAF sensor, I tried a known good one and there was no change in the running. Looking for an idea on where I may look next. Note that this is a 550 Spyder Special Edition so some of the parts are from a 987.
