1998 Maxima-Radio Noise

[NutriaforBreakfast]

Have just replaced the Mass Airlflow Sensor, 2 coil packs, and the Throttle Position sensor.
Now I have radio noise. As the engine revs the radio revs with it.

From what I have read I can do two things;
1) Change the location of the radio ground wire
2) Buy a noise suppressor

I want easiest and most less invasive solution-has anybody fixed this problem? If
so all suggestions are welcome. Thanks!

What exactly does your stereo consist of? Amps? I've always found that noises can be traced back to bad grounds. Double check all your grounds including on the engine, since it can only help make your car run better instead of putting band-aids on the problem.

Then start checking out your engine grounds. You might have knocked one loose while changing out all your parts. Best bet is probably to pull all of them off and sand them down to make sure that you have good contact.

Thanks

I will start with the battery and starter ground wires

I understand there is a ground wire somewhere by the fuel injectors but not sure where?

Do you know the location of the other ground wires?

Also I did use silicon dylectric on the ends of the plugs and coils -just a little on the tips
of each. Also put on the connectios to the coils. Should I be more generous a put some on the outside of the coils or elsewhere?

I wouldn't worry about the dielectric. Going off my '03, there is a major ground just to the right side of cylinder two (left if you are looking at it) that I would make sure is super clean because that's where the coils ground out. The other ones that I know of go from near the starter on the driver side to the frame rail under the battery. There might be more, but those are the ones that I can think of.

Thanks I will try these.
