I have a 96 tbird with the 3.8 and 167000 miles. I was getting a throttle position sensor code so i purchased a new one and installed it. After start up the car seemed to idle as it should for a few seconds up to a min. Then the revs will climb into the 1500-2000rpm range and make the car extremely hard to operate. I have heard of other people having this issue but havent heard of a solid solution. So before I go any further im hopeing someone on here can help me out as far as where to look first. Thanks!!
