93 850 GLT intermittent sluggish throttle

Post by doomtroll » Tue Jun 23, 2020 5:03 pm

I recently bought this car, and it started having this issue recently where I step on the gas, and it takes a few seconds to respond .. this is a Manual, non-turbo ...

it has the following new parts so far

New upgraded Bosch 4 nozzle injectors
New NGK wires, plugs, and coil
New Coolant temp sensor
New Fuel pump
New Bosch camshaft sensor
New Bosch TPS sensor
New Bosch MAP sensor
New Bosch O2 sensor
New Fuel Pump Relay

I never run into the issue unless it's been running hot, and there are days I never encounter it at all, what else should I be looking at?
