Hard to start engine Turbo S

Engine

Model: 964 Turbo S, Year:1994, Mileage:25000, Type of use:Street use only
I have a 1994 964 Turbo "S" Flachbau and recently it has been hard to start. I have to pump gas vigorously to get rpms up at start (engine stumbles and pops). Idol is okay once it warms up but I have noticed drivability problems with some power loss and some stumble and pops through exhaust on normal acceleration. Thought it was ethanol at first but not sure as I have used several additives to clean injectors etc. I run 93 octane with Lucas injector and fuel system cleaner. Car has less than 25,000 miles total. Let me know what you think.
