91 corsica which only 4 of 6 cylinders fired. Changed out 2 of 3 ignition coils, now runs fine. Car dies when you put it in drive and give it gas, like the trans is locked up. Can get it running by giving it gas, more than what is needed, while in park and shift it into drive. After doing this 2 or 3 times the car runs fine with no problems. Is there a senor I'm missing to check?
