So I searched both here on Driver and on my 350z but I couldn't find much information. On some of the other threads, people were saying "This is normal, the VQ is a noisy engine..." Let me assure you, this is NOT normal. Anyways, I could really could use some help guys.. Here's my situation:

I started my car this afternoon and noticed something was severely wrong. Initially the SES light came on, the car began to shutter, then the RPMs dropped and the car died. I tried to start it up again, but it took much longer than usual for the car to start (~4-5 sec. vs. ~1 sec.) The first time the engine started up, it died again. Then the second time, the car was idling REALLY rough, and the exhaust had a really bad lope to it (Similar to cam lope.) At this point I popped the hood and could visually see the engine shuttering. The hood prop and the hood were shaking, not violently, but very noticeably. The biggest issue is this: There is a loud clicking noise coming from the driver/rear side of the engine. This is obviously my biggest concern. This "clicking" runs in parallel to engine RPM (higher RPM, faster clicking.) Diagnosis/ideas/possibilities?

Tomorrow I am going to get the codes read, but I would like to have a little info on possible problems. I can shoot a video of the noise if people need me to. You guys help is greatly appreciated.

hmm one of your plugs not firing maybe? Let us know the diagnosis...

 

Lol thanks for the overwhelming responses guys! Turned out to be cylinder 4 misfire (P0304.) Changed the coilpack and all is good now. It felt like something much worse, I'm glad it was a inexpensive fix.

 

That good it wasnt anything to bad, at least i know what to check for if that happens to my car.

 

Glad to hear it wasn't a big problem for ya!

 

Yeah, the part was $100+tax from autozone, and it only took 5 minutes to change.

 

Ive got a 2005 g35 and been hearing a ticking on left side for about a year. I've major got oil leakage.

 

Sorry to hear that. Did you have a question to go along with this or are you just posting it here so that people know that this problem is happening to others as well?
