95 maxima rough idle
#2
Ask your stepbrother to check for trouble codes. It could be dirty or broken IACV, dirty TB or MAF. Test your TPS and ignition coils, and replace spark plugs. But scan for trouble codes to find what is causing this because there are a lot of things that could cause rough idle.
There are also other threads dealing with rough idle, those could help you out

Wouldn't a bad coil pack cause misfire? That should give you at least one trouble code from P0301 to P0306, which tells you which cylinder is misfiring.
But you can use a multimeter/ohmmeter or an oscilloscope to check your ignition coils. Do you have either one to test them out?

Take it to autozone for a free trouble code scan. That should show you what's wrong or which cylinder is misfiring. If money's not a problem you can always buy 6 new ignition coils to replace your old ones. 4th gen coils are known for their below average durability.

OP, if your check engine light is not on and it is misfiring, start disconnecting your coils one at a time and see which one doesn't make a change.

Average durability you say huh? Obviously you are a noob for saying such a comment. Better do your homework before coming on here with those accusations.

whatever you do DONT BUY EBAY/CHINESE COILS!!!!! cant stress it enough!!! maximas are finicky about their coils and i bought a set for 120 from hong kong off eghey because the price was right....however they were going out after 5000 miles!
Best advice, hit a junk yard and pull 8 coils....even IF you get 2 bad ones you still have 2 to play with....if not, keep em as backups or sell em....i got mine for $10 a piece at the pick and pull....

agreed!! For most 4th gens with hanshin Coils they are quite reliable...i do believe 99s have a different story for some reason with them going sooner....however i replaced them on my 95 just after 150,000 mi....id say thats pretty reliable even if u spend the full 600 a set for new ones....
