Help!!! Oddest thing happened today. While sitting at a light, the gauge cluster, lights, radio, all started going bonkers. I would get a miss in engine, and the air bag light and check gauges light would come on, the clock on radio and trip meter would reset. I then had to start giving it gas to keep it from dying. Took it on the highway for a mile and when i got off, the RPMS would stay up around 2500 as if there was a vacuum leak. By the time I got it home..........all was mostly normal. I coudln't get the car to act up again. The engine is modded and tuned (cam, intake, exhaust). The only change electric wise was I added a tach. Is my PCM taking a s***? or a coil pack?
No SES light tripped either.
I have no idea where to start

Also....it seems to have lost its tune. It also idles a few hundred RPM higher that it was.....if that helps at all.
I put a volt meter on it. Engine off and a 30 second load, battery checks out fine. Started it and meter says that charging system is working just fine as well. Have not checked the wires as of yet.
One other thing that may be noteworthy. After I did my cam swap and then got it tuned, if the engine was not up to full operating temp, the engine would have a flutter. Hard to explain. It was almost like there was no power. It would do this around lets say 2000 RPM and once I got it up to a little higher RPM like 2500 RPM it would work itself out. Only does it when its cold to warm and not every time. I just chalked it up to a tuning glitch.
