Idle and acceleration problems on 1993 Buick Regal

My car has a strange idle and also when I would go to accelerate, I will push on the gas peddle and it lags, like it takes forever to speed up. And I have had the engine tested and the mechanic said that is was the ignition module...but my brother said that he just replaced that and it shouldn't be that. I don't have alot of money to be spending on if anyone has any suggestions please answer this question for me...Oh I just replaced my spark plug wires, but this was even happening before that. It was like an all the sudden occurrence as well. I really need to get this fixed asap. thanks again for any help and advice.
