Thanks for the advice, Mike. I will give this information to my husband and perhaps the mechanic can look into it. It has been a little hesitant for several years, but now when you push on the gas, it almost feels as if some sort of pressure or vacuum is pushing BACK against you ... like you're driving into a head wind or something. It's really weird, and really dangerous.

Thanks again, and if you think of anything else, please let me know.
