Also, what can I use for the short term to fix this issue? I'd love to wrap the hole in heat shrink or something, but I don't think they make it that big.
Probably just the effects of that poorly engineered cold air intake you installed. Actually, calling it "engineered" is generous! ;-)A few weeks ago, my P5's engine light came on, and has been running horribly since. It's a manual transmission, and getting started has become really tough. I try to take off, and I can feel the engine shake and it seems like it's going to stall. I push the clutch in, and either give more gas or just shift into 2nd (either method seems to help a little), and then it also lunges with the clutch disengaged and steady on the gas. I've lost about 3-4mpg in fuel economy.
Well that is VERY promising then! I happen to still have my old coil packs that my dad advised me to keep, plus the new ones are likely still under warranty.
EDIT: the code reader says cylinder #1 misfire, and even better news...there's a lifetime warranty on the coil packs.
