just to add a note to this too, on most cars you can elongate
the holes holding on the TPS sensor or slot them, then you can
actually adjust the sensor for better throttle response, and sometimes
idle too. Youll need a simple eletrical meter with probes like a Fluke
or something to do it, but its an old trick we did on Fox body Mustangs
back in the 80s and 90s. The sensor tells the ECU when the throttle
plate is open and closed and how far its open by voltage, usually a
range of 1.0 to 5 Volts. So we could slot the sensor and adjust it so
it read .98 or .99 at idle, so the throttle response was improved
off idle . If the voltage is anything over 1.0 at idle, the idle would
be higher then normal, which you want to get away from.
