If you recall from this thread, Anthony suggested I check my TPS voltage.
With that in mind, I immediately suspected some had performed the infamous ricer "TPS mod". Supposedly, setting the TPS to .98v at idle is supposed to increase throttle response and power output. The problem is that if TPS voltage goes over 1.0v at idle on a speed density system,your engine will surge and even stall. This is a particularly bad thing to do to a speed density system, because, as we all know, it imputes airflow from the MAP and TPS. TPS should never be set above .95v on a speed density 5.0. I didn't even bother setting it, I just loosened it, let it snap itself back, and then tightened up the screws. I now have a nice steady 750 rpm idle and the butt-o-meter noticed no loss in power or throttle response. Nuff said.Originally Posted by frankiesaysrelax
