1970 cutlass 350 rocket
car runs and idols fine but when you hit
gas hard it stalls between gears you let
foot off gas it starts back up if you are
light on the gas it will shift through all
gears what could be causing this
Sounds like a accelerator pump failure. Was the carb gone through when this trash for fuel was forced on us?
Time to clean, rebuild, and tune the carburetor correctly. $400
No just got car but it seems to be very responsive when in park only when rpm gets high between shifts will it do that thank yall I'll try carb let ya no I was thinking it was trans mission
You might also want to check your fuel pump flow and pressure, as you say it happens at shift points and that is when fuel demand is the higest
Okay also my trans started leaking behind torque converter so I'm thinking I may need a new converter would that make this issue cause right out the gate it's balls to the wall then when it shifts is when it stalls then if you feather it it will keep going
That is most likely the front pump seal and not a torque converter leaking, as the tranny has to be at least slid back far enough to get to the front pump housing you should have the converter checked, there is a slight possibility that it maybe trying to lockup, but it is very rare on this style of transmission. I still think you trouble is fuel related.
Okay will check fuel pressure tonight and get back with you thanks
