Auto Scanner: 2000 Nissan Frontier misfires randomly

Q: I have a 2000 Nissan Frontier truck. It has 40,000 miles, and I have been the only owner. It misfires randomly. It has stalled once at a stop sign. There are no check engine lights on.

I took it to my local mechanic to get it repaired. They told me that there are no computer codes or other indications shown. They checked the vacuum, fuel injectors and did a complete tune up. They checked and cleaned the injectors and replaced the upper seals that were showing signs of deterioration. The mass air flow sensor was checked. (The unit was replaced, and when no improvement was noted, the original unit was put back in.) They called and consulted with other mechanics, to no avail. They gave up and suggested I take it to a Nissan dealer. I did. Nissan had it for three days. They consulted with Nissan national service. They also gave up.

The service manager said that in his entire career, this was only the third car they could not diagnose and fix. They suggested I drive it until whatever is wrong completely fails and they get a solid computer code. I am not comfortable with this.

All who have looked at this truck verify that it misfires (5 seconds). They cannot find out why. They all seem lost because the computer is not telling them anything. I did get a check engine light once, but that only indicated that the engine was misfiring. No solid code to indicate why. Do you have any suggestions?

A: The issue here is that the problem is not consistent. I am happy to see people are not throwing parts at the truck until they happen upon the right part. A few ways to isolate the problem would be to drive the truck with a flight recorder attached. When the misfire occurs, you would press the record button.
