CHEVROLET BLAZER GAS PROBLEM

1995 Chevrolet Blazer

Hesitation.

my 95 Blazer 4.3L Vortec started to have really bad hesitation at 2000 RPMS less than a week ago. So I let it sit for a few days and the problem when away. But only if you are slow on the gas and its cold, as soon as it warms up and if Im heavy on the gas it starts to hesitate to the point where is stalls and I get a check gauges light and my battery indicator comes on. Fuel pressure is fine.

could it be the EGR valve needs to be cleaned or replaced or is it the fuel filter?

I also have done a carb cleaner treatment and a heet fuel line antifreeze treatment.
