good day, everynyan,

i've been having some real silly problems lately with my Z. for starters, car was overheating badly in 30C weather, i assume it might be the broken radiator fan, so that's to be determined. unfortunately, i daily drive my Z, and i drive for work... so i've been having to suffer through with driving it when she's running at tad hot (MY FAULT !).

anyways, i don't believe my problem to be related to the constant overheating (but it definitely doesn't help). i had a new cold air intake installed, and i'm a silly guy so i bought it for a g35 instead of a 350z. ! what an idiot... anyways, the fitment was all out of whack and the filter wouldn't hold into the intake tube, so i took it to a shop to get quoted for some custom work yayaya, it's getting done soon, but for now i took the shroud off of the filter so that it can fit properly.

anyways, ever since then sometimes i get misfires, my engine feels a tad bit sluggish and it shakes superrr bad, rpms will move from below 1 up to 2, all at normal temps as well. i noticed that if i pop my hood the problem does go away.

with that information, i assume that the engine is NOT getting enough air. only logical explanation from a guy who has no idea how engines work. unfortunately the parts the shop ordered are about 2 weeks away and that's too long for me to wait without trying to ask if anyone has any other ideas for what it could be.

i also got an oil change done recently, car might be burning oil, maybe they put in the incorrect oil. i got no idea ! ! ! i don't know how cars work i just drive em ! ! !

just wondering if anyone else has faced a similar issue bc it's really annoying having to drive a car that speeds up like an 86 . . .

thanks gang

 

I appreciate the self deprecation, but it appears you're in way over your head. For starters, fix the broken fan. If your car overheats, then you're going to have a lot more to worry about.

Second, put the original air intake back on and see if the problem goes away.

Third, if you must have a cold air intake, buy one for a 350Z. That's got to be way cheaper than trying to custom modify an intake for a G35 when there are plenty of readily available CAIs for the Z.

 

Been awhile since I fixed all these problems so I guess I should do my due diligence!

Turns out the car was overheating due to some debris, that was a bill I was NOT happy about lol... Nothing major, no coolant issues, no cooling issues, just a bit of debris...

As for the engine making funky noises - I was correct about the CAI not getting enough air. I decided to wait it out instead of putting the stock air box back on, got parts, and we piped the CAI to the front bumper.

As for it being cheaper to custom modify a G35 intake, it cost me ~$600 for the CAI (I think?) and $400 CAD to get the custom work done. All in all, not that bad, kinda worth it, and I learnt from my mistakes hahaha.
