Hi new 350z owner. Bought a couple days ago. Its an 03 140K miles. Has a replaced clutch a lightened flywheel and aftermarket intake. I replaced the power steering pump cause it was going bad also did an oil change. Just trying to give all the info i can about the car. Im having two problems with it.

1. When i bought it the guy told me that ignition coil 6 was bad and had to be replaced. He gave me the part and i replaced it. Took it to autozone and now its giving the code p0300 2 times. Wondering what it could be since the misfires are very small and not very noticeable.

2. There is a leak and i dont not think its oil since i check the oil level and it is good (Oil gauge is broken). So im thinking it could be the slave cylinder because today it was a very hot day and i read that affects it. On my way home the clutch pedal would stick to the bottom and i would have to bring it up with my foot. Later that night i drove it again and the clutch was fine moving back and forth like normal.

Just want some opinions on what the problems could be and any help. Thanks.

 

Check the fluid level in the clutch MC reservoir. If it's low, take a look at the slave and see if it's wet/leaking. If the fluid was low and the slave is dry, top up the reservoir and bleed the system.

I'd fix the oil pressure gauge yesterday, and would never even consider buying a car with a non-op gauge, so hope for the best.

 

Checked the fluid today and it was full.

 

Maybe it just needs a bleed. Only one way to find out.
