Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Stumble at 1500 RPM

Okay, 1998 Grand Prix, Naturally aspirated 3.8L has 100K on it,suddenly started stumbling at 1500 RPM under load when warmed up. Originally thought it was a bad tank of gas but ran Sea Foam and Chemtool thorugh it, changed the fuel filter and PCV valve. No real improvement. Maybe a bad Throttle Position Sensor or a fuel pump but it isn't throwing any codes....
Advice!

Thanks!
