got some codes need help

[buschegt]

Ok so I have a99 gt, and having some issues with acceleration, so I got it scanned and got p0141 and p0134 so I'm needing some direction please help

 

[dsmuts]

Sounds like your front o2 is bad.

 

[buschegt]

So is that up stream or downstream? And both the codes are o2 sensors so the second o2 is for my cat right?

 

[dsmuts]

Upstream. The p0420 code is for the cat.

 

[buschegt]

So my cat could be clogged or could the sensor be bad?

 

[dsmuts]

Sensor is probably bad.

If you listed the names for the codes, we could probably easily tell you if it's an O2 or not.

When you list codes, please ... list the name.
