This week drove fine on Tuesday. Loaned to Dad on Thursday. Drove home fine. Made some stops, and after one stop, it coughed and hesitated after leaving a stop sign, making a left hand turn. Next stop, would not start. Turned over. Seemed like no spark, but heard several muffled explosions, so at least a few cylinders seemed to be sparking.
Called for a ride, and heard from my father that after he ran his errand with it and backed it into his driveway, it wouldn't start after unloading. He waited an hour, and then it started.
I waited a few hours, got a ride to the parking lot, but it still wouldn't start. Tried again 3 hours later. Still wouldn't start. Went back Friday morning before having it towed. It started like normal.
I drove it to the nearest auto shop and explained the problem. They called back last night and said they can find nothing wrong. No charge, come and get it. I left the lot and half a block away is the same corner it hesitated at on Thursday. Took the same left turn from the stop sign, and this time it died in the intersection. After coasting to the side of the road, it started back up and I returned to the auto shop.
They still can't find anything wrong. Anyone have any ideas?
