This morning on the way to work I ran into an odd idle issue.I pulled off the highway after cruising for an hour+ and arrived at some lights. As I downshifted (5 spd) I noticed that the rpm wasn't dropping between shifts but hanging up around 2000rpm.When I stopped at the lights, it sat at 2000rpm for a few seconds then slowly decayed to 1600. I blipped the throttle and it dropped back to about 1400 and then slowly settled to about 1250 by the time the lights changed (couple of minutes, it's a busy overpass with a long light delay).It continued to repeat at each stop/corner to work (another 4 stops). Once in the parking lot, I let it settle to 1400ish then cut the engine and immediately restarted. It started completely normally and settled to a normal idle with no issues.Any thoughts on what might be happening? Am I looking at something failing (sensor)?It's a stock (engine) '95 GT with about 175,000km on the clock (110,000mi). I'm running a 3.9 rear end with a stock T-5 and a DM SpeedCal to correct the speedo. I cruise at about 2350rpm on the highway at around 110 kph (70mph).Stew
