How long since over-all tune-up? If you think a fuel issue, did you check fuel pressure? With TBI the pressure is usually around 9-13 psi. Can you see the fuel injector/s spray pattern?
Do you think the knock sensor may be your problem?
With intermittent issues, you need to test when problem is ongoing. I know it is a pain. An intermittent rpm signal can drive you crazy. I need something to point us in the right direction?
At the top of page is a repair guides link, a lot of good information.
