I have read in a few places that you should put a little dielectric grease inside the tip of the coilpacks where it contacts the spark plug. I am replacing my rear coilpacks now and am wondering if this is right, or if it will accelerate the wear on them?

How many miles on your max when you replaced the coil packs? Where did you get them and how much did they cost.

by the way Nice car. My '99 is silver but i think it looks better in black

I used dielectric grease on the end of the boot where it contacts the plug, it keeps the boots from rotting or sticking to the plug and keeps moisture out. It won't hurt thats for sure and will make the coilpacks last longer.

I have 120,000 miles on my 97, and I only replaced the rear three today. All of the front ones tested out OK, and I just spent about 1000 dollars on my front end, coil-overs, ES inserts, etc... Will wait until they are bad.

I got them from Mossy Nissan and I don't remember how much they were. Look up their online catalog and you will see them. Mine are the Hanshin ones.

I just started getting an ecu code of 201. I replaced the sparkplugs and knock sensor but am still getting the code. Do you think its the coil packs?

what do you mean by ECU code of 201? In the stickies there is an explanation of how to check for codes in the ECU by turning the screw clockwise and counter. Check that for your definite answer.

I see more and more people with huge sigs........ May want to resize the sig.

It is easy to check for codes, just turn the key on and move the screw L to R a few times, the code(s) will start to flash. Same process to delete the codes L to R, just make sure the screw isn't left in the diagnosis mode, all the way to the other side. Coilpacks can be tested to make sure they are within spec with a mutimeter, in the how to section.

I did check the codes and got 201. Then i looked it up in the sticky and it said: Diagnostic Trouble Code 0201 indicates a problem with the ignition coil and power transistor.

I thought it might tell me what the problem was or what which coil was bad. I guess what im asking is does this code, 201 mean i need to change one or all the coil packs??

You need to pull each coil pack out and test them individually with a multimeter. http://forums.maxima.org/showthread.php?t=254238 check post #21
