I just replaced a TSP on my dau.s 1998 Jeep Wrangler with the 2.5L 4 cyl. 98,000 miles on it. Stock. I just put a Advance Auto TSP on it and it now runs at 2,000 rpm idle. What could cause this? I noticed the TSP has two ears that fit around a blade on the TB. I thought it could only go on one way. Maybe not!? What can I check? Is there an adjustment?
