When my 1996 5.7 vortec is cold it will bog down and sometimes stall when put into drive or reverse. And until it’s reached operational temperature it has a 1-2 sec hesitation. When the engine is warm it is completely fine, no hesitation and no stalling. I have a summit racing 1065 cam. If someone could point me I the right direction I’d greatly appreciate it
Below are the parts/services that I have replaced/serviced in the last 6 months since owning the truck:
Fuel pump, tank and filter
Spider injections (GP Sorenson)
New TPS
Cleaned throttlebody
New spark plugs and wires
New distributor cap and rotor
New air filter
Cleaned EGR
New IAC valve/sensor (was stalling a lot before replacing this)
New Oxygen sensor (was throwing a code)
I have also tested the fuel pressure and it’s 59 PSI during idle and priming
New ignition control module
