I thinkbthe tps sensor on my gs gave out. Car won't even go into gear unless its completly cold or I have to detach the battery cable and connect it then it will run fine for a while. I was wondering if you guys had any idea what the problem could be. It seems that its a sensor because it shift just fine when its cold or I detached the battery and reconnect it. Has all the symptoms of a bad tps sensor. So unwashed wondering if anyone had a DYI STEP BY STEP instructions on replacing it and where its located
