Just a few things or facts come to mind. Being that your motor is basically stock. Vac at idle should be around 20 inches, Map value should be no higher then 1.0v (more around .88-.92v) at idle and operating temp. I am not sure what you're seeing for st ft and lt ft? Are you throughing any DTC's for the lean issue? (with the stock ecu) Have you tried a different wide band. Have you checked the fuel pressure? I know you replaced the fuel pump but you may have a fpr issue? May need to try another set of injectors.

Idle i see around 26 vac. Yeah injectors are my next option. Map is fine right around 90. No dtcs for lean. I did use seafoam today so still waiting
To burn the rest of that out to see if theres a diff. Even if my wideband is bad i still dont have power. So i rly dont think my wideband is bad. Its less than a yr old as well. As for fuel pressure. Impossible to check unles i tap the fuel rail. At that point i might as well get aem rain and reg

Your Op temp is good. Map and vac sounds fine. As far as checking fuel pressure you will need a special adapter where the pulsatin damper is. Honda part number 07VAJ-0040100. That with a ordinary fuel pressure tester would work to check. If timing and valve adjustment is spot on then yes I would say trying injectors. Good luck buddy. Hope this one gets found soon.
