[Turbo Red]

I have a 2003 GT (auto) with 43K miles. Over the past 4-5 months I have noticed a decrease in power while going up hills. This week when I stepped on the gas (not hard) it chugges, missfires and backfires up to the new speed and runs fine when I reach the speed I was looking for. Seems to be wores at speeds >35 MPH. I remember a TSP for like problems > then 5000 RPM. All my problems happen in the 2250 to 3500 RPM range.

Any thoughts???

Thanks
