Swapped engine on my 05’ G35 sedan after a friend broke the original block of my engine during a rear main seal job. It sat in his garage for about a year before we got the new engine.

Resealed the new engine, hooked up harness, installed into my G35. Start the car up and it runs. Only issue is now no throttle response at all.

Car ran fine before the job.

I’ve replaced the pedal, throttle body, MAF sensor, done ECU AND throttle relearn, I’ve checked for codes and we’re not getting any.

Any idea what this issue is? Maybe bad injectors or gas? Possibly bad ECU/ECM?

Seen some videos listing the cats could be clogged, or maybe something else????
