well they dont do engine readings i was told it has to be 1996 or newer..... but neways heres a way to save 80 to 100 dollars! find your diagnostic plug under glove box typically, look for plug with two wires attached might be stuffed up behind your glove box more then some other wires, take that plug and run a paper clip or small needle pliers and turn your ignition to on ( dont start car) then watch your check engine light it'll flash. Long Flashes equal 10's, Short Flashes equal 1's. so LONG LONG LONG SHORT SHORT SHORT SHORT SHORT SHORT SHORT= 37 hope this helps out. The throttle position sensor is used by the computer to determine how much fuel will be sent to the cylinders from the injectors. The engine may run rough, accelerate poorly, run extremely lean potentially burning valves or extremely rich wasting fuel. To properly determine the cause of the check engine light you will need to use a code reading device. Many of the auto parts houses, such as Auto Zone, Checker Auto, Kragen Auto or Schuks auto have code readers that you can borrow or rent.
