Well another problem has surfaced. Posted back in July about a stall, then no start. Replaced the distributor, cap, plugs, wires, power stage, radio suppression relay, vacuum lines and the knock sensor. Added Chevron injector cleaner. The car (1989 740t) still didn't run good. Finally took it to the Volvo shop. They found the problem was a bad power stage. I had purchased a HUCO power stage and it was bad. It was replaced with a Bosch unit and the car ran great. Now it appears the problem is back. Car starts, then after warming up is put into drive it stalls. First time it started right back up. Second time (a week later) it took waiting a few minutes before it would restart. After restarting car seems to run fine. Any help or ideas would be much appreciated.
Thanks Brad
