No codes?

This is how my 89 acted exactly as you mentioned when my injectors were toast.

Could be the injectors. My 87 is having the same problem right now. No back fire for me but when I go full throttle it bogs bad after it goes above 190.

I will be replacing my rad, water pump, and cats. I have new injoctors but they test well.

Any ways good luck and this is why I love my vette it always lets me know when its not feeling well and its an excuse for me to spend money on it and the wife wont get mad. I just say "But its broke".
