Delay in acceleration & RPM'S when stopped

[ababel17]

So I just got my car back from my mechanic less than a week ago after dropping $1500 on a new catalytic converter & other emissions CEL issues. My new problem happens when I am stopped...whether it be at a stop light or in traffic etc. When I step on the gas I get no acceleration or rpms for a good 3-5 seconds. I only noticed this yesterday but it seems to only happen if I'm driving and I slow down to a complete...or near complete stop. Please Help

This sounds similar to a dirty throttle body symptom I had a while back. If you want to clean it and want a peace of mind, DO NOT take of that throttle body connector. Because you'll have to do relearn procedure, it didn't work with me manually an I couldn't find anyone with a CONSULT who could do it for me.
