Remove your front O2 sensor, from the pipe. Drive it around and see if it's better. May be a plugged cat. And check your plenum.

 

It dose have good flow threw the tail pipe as well and do u think it might just need a computer reset after the new o2 sensor is installed

 

Unplug the O2 sensor, and see if it runs any better. If it doesn't, physically remove it from the exhaust, and try again. See what happens.

 

Got an appoinyment to stright piper and see how that goes thanks you guys much appreciated
