G37 Rough Idle Need help!
Hello All,
Ive been having this weird issue with my 09 g37 coupe with 125k miles.
The motor always has this weird stutter and shaky idle. It just feels like the engine is missing or something.. I figured it was probably time to change the plugs and clean throttle body/ maf sensor. I went to a reputable nissan indie shop who is extremely knowledgeable about VQ motors. They agreed that changing the plugs and cleaning the throttle should fix the issue... Well I just got the car back today, and its exactly the same.. Engine still has that weird miss feeling.. and idles weird.
What else do you guys think it could be?? Im going to call the shop tomorrow and let them know about it.. they said the would charge me another diagnostic fee to figure out what it is...
I just want it to idle correctly.. Its been doing this since I bought the car 3 weeks ago. Motor pulls very nice, no issues with performance at all.
Please help!

If you paid by credit card request a charge back and go to an Infiniti dealer for a correct diagnosis.
Buying cheap very often results in buying twice

I didn't buy the car from Infiniti. I bought it from a little used car shop. Car is sold as is.. Car fax was clean, and I can see that the car was services regularly for oil changes and Infiniti dealership.. Car is super clean and drove very well on the test drive.. It just developed this weird issue a week or so ago.. And has progressively gotten worse..
