Wow what a difference! I put Autolite Platinums in two weeks ago and have not liked them since.

Today I changed to the NGK Laser Cut Platinums. It seem to run smoother and accelerate better. When I pulled the Autolites, they looked like they had been in there for 5 years. What a bunch of junk!

Good deal...
Glad you like them.
These plugs should last you quite a long time!!

I would reset your ECM.
Let the motor & computer learn the changes.

Pulling the fuse for the ECM should be good enough, right?

Yes. Fuse N:

Well, I just replaced my Bosch 4508s with the NGK Laser Plats No. 7781!!

I replaced them because I noticed a little lack in pedal response from the Bosch 4508s. All I can say is that these are better than any Bosch or Champion plugs I have ever used. Really! More responsive. Much better! I also noticed that the NGKs are about 1/4 inch longer into the cylinder head. Could this make a difference?
I was wrong about my previous Bosch 4508 review in the Bosch IR thread. :guillotine

I pulled my Bosch Fusion Ir's, dropped in some NGK Laser Platinums, and pulled the N fuse. I have noticed a big difference in acceleration and smooth engine idle. I have tried the Bosch +4's and the Bosch Fusion Ir's, neither compare to the NGK Laser Platinums. OE style is the way to go.

I have to agree with Tom. I tried switching out my NGK's after 35k for a set of Champion Plats. My performance bit and I lost a few mpg's. After a week, I put the old NGK's back in and regained all of the mpg I lost. They are definitely a great plug.

Is this a good thing to do after completing such maintenance items under the hood? I just changed my plugs out about 8,000 miles ago but did not do this.

How long to you have to pull the fuse for? Will this affect any custom settings inside the car such as memory positions, presets and such or just the computer under the hood?

If it can only help, I'll do this. I just wondered what the benefits of pulling this fuse are.

Thanks!

Pull the fuse for 20-30 minutes. I have heard that 15 will do it, but I like to be sure when I do these things. Also, remove the TCM fuse as well. Reset the adaptives in the tranny....good time for this as well. You will not lose any retained memory items, as they have their own backup power sources.

Thanks Tom,

I will pull both the ECM and the TCM then just to reset everything!

Should I drive any different then I normally have in terms of getting the computer to learn my driving habits again? Such as if I go easy and slow, will it be less responsive if one day I need to step into it? Or should I drive it somewhat hard off the bat so it learns that when I need it to go, it gets up and goes? Or does none of this even matter in the first place? :)

Just curious how resetting these things may affect it's driving habit....

However you want it to "behave" is how you should drive. If you are normally aggressive, then drive it like you stole it. I have mine trained to shift around 3200 rpm when I normally accelerate. When I stomp it it acts like a normal automatic transmission as it downshifts and kicks (CENSORED).

OK, this may come off as a dumb question but when I took off the cover to the fuse & relay center, it mentions I should disconnect the negative (-) cable before servicing...does this include just pulling the fuses too?

Plus, to be sure, the ECM is letter 'N' marked '30AMP ASD' and then TCM is letter 'Q' marked '20AMP TCM', correct?

Thanks!

Nah. (Besides, pulling the negative cable would remove power from and reset everything without touching the fuses anyway.) :)

For pre-'02, yes. But for '02 and later, the TCM was combined with the PCM, so pulling fuse N does both (for '02 and later).

Thanks Bill! I just noticed under the fuse and relay cap that the TCM is listed as letter Q with the letter N being listed as ASD, threw me off track as I have an '04 and not a pre '02 model.

Reseting the TCM & ECM right now!

Can I also reset the tranny from doing this?

Pre-'02, to reset the TCM, pull fuse Q. To reset everything all years, disconnect battery (disconnect neg. jump post, located on passenger side strut tower).

just want to know. when you say pull the fuse? do you replace it or put the same one back in?
 #223695  by Craig300
 
same one back in
 #223710  by tinman
 
Pulling the proper fuse is just like disconnecting the battery. Leave the fuse out for 15-20 minutes just like you would leave the battery disconnected. And just as you would reconnect the battery, put that fuse right back in its proper place. Unplugging the fuse is just a lot easier.
