So My 95 4.3 has been acting weird. Seems fine when accelerating and cruising but when I get to a stop she idles low and wants to die. Also lost power brakes. Pedal really hard. So first thing I did was to pull sensor connections 1@a time. Throttle position sensor when disconnected brought idle back to normal. Replaced sensor but when plugged in same low idle. Also noticing strong fuel odor under the hood. What next?
