I recently had timing done again after previous mechanic messed it up. No more skipping, sputtering or back firing. However, when I’m at a complete stop and mash throttle, it wants to bog down for a second then catch at wide open.

Been chasing this sine I bought it…
. New distributor
New wires plugs
New fuel pump and filter
New mass airflow
New air filter
New camshaft sensor
New starter
New IAC sensor
No vacuum leaks
Does have exhaust leak after first o2 sensor
TPS valve checked seems fine
New temp sensor

Anyone got an idea before I change these spider injectors??
