Hiya all, my 986 Boxster (1999 127,000 miles) is running poorly on tickover i.e feeling like it isn't running on all 6 cylinders, however when I set off it seems to run o.k. I've since changed the oil, filter and plugs but still have the same problem and when I plugged in the diagnostics it reads fault code 300, 301, 302 and 303 which I gather is indicating a misfire on one sides bank of cylinders.
Has anyone any ideas as to what my next move should be? All suggestions are welcome.
Thanks, Andy Bruce.

Coil packs would by guess, check to see if any are cracked.

Aye, cool packs. I got a set from Design 911 which were reasonable, I think they were less than £150.

Make sure they're the new ones starting with a 997 part number.
