'90 Problem after Warm-up
My '90 vert, 6 speed has a serious idling problem. At about the same time the shif 1 to 4 light comes on, the car begins to run rough at constant throttle speed. It also does not want to idle, and when fully warmed up, does not want to start. We've replaced TPS, IAC, temp sender, plugs, dist cap, rotor, and plug wires, have added BG 44K, and have changed oil and filters. Under acceleration it runs fine. After a short cooling period it starts right up. Is there a set-up sequence for this car? Any suggestions are welcome. Thanks
