Hi,
You could check your TPS sensor on the throttle body. It has 3 wires coming out of it[black oval shape]
Witha digital voltmeter , measure the voltage between black wire and green or orange wire[depending what year it is] . I stick a pin through the insulation to do this, with the key on, engine not running.
It should read about .9 of a volt. To optimize the computer you should adjust it to read exactly .997 of a volt. to do this loosen the 2 screws holding the TPS sensor and wiggle it to get maximum reading. If there isn't enough adjustment you can take a drill bit and make the holes in the TPS slightly bigger and try again to get .997 volts. Do not adust it over 1 volt.
