Code 34

1989 TPI car. All original
very very intermittent. Twice a year, code 34, motor will stall, and be difficult to restart. Then it goes away, no SES light. and it runs fine for another 6 months.

Not that I drive the car more than 500 miles a year.... but I can't be stalling out in the middle of an intersection.

Car is all stock, MAF is original. I see reference to a MAP sensor, but it's an MAF car.
