My VQ30 Max had a small little shaking/rumbling action going on when I was in idle, it was smoothed out when I revved it. This was after my SES light came on. It never did anything like this before, it always purred in idle. It did this on my short trip to the bank, it stopped shaking all of a sudden and went back to being smooth. Right now, it's smooth, dunno if it will come back. Will bad o2 sensors cause this?

I'm going to AutoZone to pull codes after work. and F.Y.I. Kragen does NOT pull codes.

Any input would be great, thanks .org!

 

Bad ignition coils or bad MAF -- post the P-codes here.

My money's on coils BTW.

 

Eh, I wouldn't peg the coils right away man. there are many things that can cause this issue.

do you have an intake? My car does the exact same thing, and as soon as I put the stock intake back on, the idle is perfect again.

but yes, we need codes to tell what the issue is...

 

My car did the same thing last night. It never has before. I have not driven it today though, so hopefully it wont still be doing it. Question: I bought my car a month ago and I dont know if any of the coils have been replaced, is there any way to check to see if the coils are original??
