01 taco rough idle/throttle response. engine light on

i have a 01 taco v6 with about 132,000 miles on it. Just recently it started to idle rough when it got warm. My throttle response is also really bad when i am sitting at a red light or just have the clutch in and rev it up. when i let the gas go it wants to go to 300 rpm for a bit and it almost dies. My check engine light just came on to so i dont think its something i need to just clean(like a throttle body). Is this a O2 sensor going out?

 

Read the code ... could be anything.

 

x2 check codes to see if O2 sensor...

if not, fuel filter and MAF sensor needs cleaning...

 

I vote MAF or o2 Sensor or Idle Control Valve....

 

I would vote for the Sea Foam treatment made mine run like it was new

 

the code was p0120 i think. I changed the tps and it made it a lot better. My next step is to seafoam it.

 

change the plugs
