No codes show up and has recently been tuned up (plugs, wires, distributor cap and rotor.I think it is one for the sensors on the throttle body but don't know which one?

Your throttle body shouldn't have anything to do with spark? Are you talking about a misfire or no spark at plug?

I meant to post that last answer on another post. Sorry about that.
If idle issue, clean the throttle-body and check idle air control.
