My reader is showing only the single code (p0301). The code pops up intermittedly (ie. it's not always present) sometimes with the MIL light, sometimes not.

The most noticable effect is the drop in rpm and a bit rough running.

Should I be scared? Would a failed/failing MAF cause this or should I look elsewhere? which is cylinder 1? passenger side at the firewall?

If you need more information just ask.

I'm pretty concerned atm.

Thanks guys in advance.

P0301 Misfiring, Cylinder 1

Check for a bad coil pack. poor electrical connection or even a bad spark plug.

On a Boxster cylinder 1 is right side - cylinder closest to the front of the car (on that side).

Update. I backed off the coilpack and wiggled it a bit and re-tightened. It wasn't as tight as it should have been. 15mins at idle with some small reving and no recurrence. (knock on wood). When the exhuast cools down i'll double check the pack and go for a test drive.

I don't want to do my happy dance just yet but yesterday the rpms would have easily fluctuated by now.
