Sounds like your narrow range TPS is out of adjustment or has gone south.

I just had the 18 code last week and the TPS was in fact BAD.

I just did the test and adjustment of my TPS on the 90 vert (with JDM Tii). You'll find the step by step instructions in the FSM. And you'll find the FSM online in the 2nd gen FAQ.
