My sick baby
Hi everyone. Upon getting off work tonight at 1am my car started to stutter and not accelerate smoothly. Check engine light and then check VSC came on. Drove it home and here are the codes:
P0300
P0301
P0308
Looks like a misfire of some sorts. Any ideas where to start? Car is an 01 with 109k miles.

Have you replaced the spark plugs or are they original? You could swap the ignition coils on cylinders 1 & 2, and 7 & 8, then clear the codes and start the engine to try and isolate if the ignition coils are faulty. If you then get codes 302 and 307, then it's likely those two coils.

Ok checked on the engine. The vaccum box and has a crack in one of the hoses (I've known that and have the hose connected with tape). After reattaching that hose, I started the car
up and I am still getting a misfire in cylinder 8. Would the next step be to replace the spark plug? They are original to the car as far as I know.
Can the whole vaccum box be replaced?

If it's okay swap the coil pack with one from another cylinder as stated previously to see if the misfire moves to the cylinder with the suspected faulty coil.
Double check again that there are no vacuum leaks before proceeding. These often make a hissing sound.

1. Is it okay to just replace one coil pack or will it cause problems for the other ones?
2. I'd like to replace all of them and the spark plugs but at 85-100 bucks a coil it's not cheap. Is there a reliable aftermarket alternative for the coil packs?

Looks like a coil pack issue after some more testing. So questions now:
1. Is it okay to just replace one coil pack or will it cause problems for the other ones?
2. I'd like to replace all of them and the spark plugs but at 85-100 bucks a coil it's not cheap. Is there a reliable aftermarket alternative for the coil packs?

Ok I changed the coil pack on the number 8 cylinder and the spark plug on cylinder 8 and 6. Cylinder was my problem child, and there was oil in the spark plug tube. Is that a big problem?
The car runs amazing now, no lights except the check VSC popped on but the car is running great.
Also I was having a horrible time accessing cylinder 2 and 4 to change the plugs. I will do all of the plugs eventually but I ran out of time tonight.
