Not necessarily! I have fixed hundreds of them with the noise filter. Here is how to test it. 
 
Attach a scope to the TPS wire at the PCM and monitor the circuit ona  5 volt scale. With the Key on and Engine Off, the circuit should show a straight smooth line at about 1/2 a volt. Now start the engine. If the straight line is now a severely jagged line, and voltage is very erratic with the engine running, then a noise filter will fix it.

Here you go. But I would check all grounds and power connections to batteries and fuse boxes, this is most always the issue with these things.
 
  
 
Hope it helps.

 Does anyone have the instructions for the No Bull noise filter installation. I have one on the shelf but the instructions are missing.
