Fuel injector issues and hydrolocked

Hey guys, my 92 rs v8 305 Tbi, is suffering...it was starting rough in the morning. My mechanic said it was the fuel injectors getting gas in the plugs. So, we did a rebuild on the Tbi with new injectors.
Oreillys auto parts sold me injectors with a -p after the part number...I didn't think anything at the time. (and it may not be an issue?)
Car is even worse now it starts rough and when I accelerate, it hesitates like it's going to stall.
Mechanic says may be the plugs that were flooded by the hydro lock? Or the injectors may be bad?

Since you don't have a carb, you might find you get more help on the TBI board.

what makes you think it was hydrolock? hydrolocking a running motor bends stuff

I love how everything is always blamed on the carb or injectors. Change out your spark plugs, spark plug wires, rotor button and cap and report back
