1999 Pontiac Sunfire TPS

I just recently replaced the TPS on my 2002 sunfire with the Ecotec motor. While you have a different engine in yours, I cant imagine it being that much different. Look towards the front of the engine. There should be a box that connects to the tube going to your air filter. Take that tube off and then the box and you should be able to see the TPS and go from there. Hope this works for you.
