Random misfire cylinders 1-5

Misfire after timing belt replacement 

[Mggness]

Has anyone responded to your misfire question? I have the number two and number six cylinders that are misfiring, as well as number eight misfiring some of the time. They are all on the same side.

They are all on the same side.

I have had another tuneup and neither the Lexus mechanics not two independent mechanics can determine what is causing the misfire. I would be grateful for any advice and counsel.

It is a 1995LS 400, V – eight cylinder sedan. And I also had recently had my timing belt replaced.
