Strange noise

I have purchased a 1990 reatta,i have replaced the erg valve cause it was cracked,That did not solve my problem.There is almost a train whistle noise when i try to accelerate and the car hardly moves at all.I noticed there was a little "walking" of the tensioner when i would hit the gas while it was in park.Replaced the tensioner pulley and it is even worse now.Any ideas what is going on??

Very little info here to go by. Do you mean the car will not move ftom a dead stop?

So, you bought the car, even though it wouldn't move?

Have you checked the condition and level of the transmission fluid?
