1990 Buick Century 1990 Buick Century

Car stalls while driving after about 30 to 45 mins. If you switch to neutral before stall, it won't stall but as soon as its put into gear(forward or reverse) it will stall. It starts right back up, every time. Just before the stall there is a heavy vibration, like if you were going over a rumble strip, then it stalls.I was told it may be a max airflow sensor, but I wanted to know for sure or atleast get several opinions. The max airflow sensor is kind of expensive, otherwise the car runs like new.I bet it has another 100 to 200,000 miles left in her.
Thank You,

ues sir she still has plenty of life left in her. Your problem is a sticking torque convertger clutch solenoid in the transmission. If you look down at the transmission from the top you will see a white electrical plug toward the radiator side. Unplug this electrical connector and your problem will be gone. You can drive forever with it unplugged and wont harm transsmission or you can have the solenoid replaced and keep the torque converter lock up. (Its basically a 4th gear in the transmission) you dont have to have it. Most people just leave it unplugged. I would replace it if it were me because im *bad word* about my cars. The cost to repair can range from $50, if you do it yourself to about 300 if yiou take it to a shop. Hope this helps.

I looked everywhere I couldn't find any white wire coming from the front of the tranny. Can you be more specific?Drivers side or pass side?Is wire on top or underneath?I didn't see any wires that have a connector on or coming from the tranny.I even pulled both front tires, but didn't see it. Thank You for all your help, any further assistance would be greatly appreciated.
