I'm gettin a code p0301 which is cylinder 1 mifire. Is this a spark plug problem or something else I should look into when I change plugs. I haven't had the autolites in for 10,000 miles yet. Should I be running a different plug because of my setup? I have the FMTB, K&N FIPK, PPH headers, superchips, and flowmaster exhaust. I also have a good set of plug wires the Durango Dude suggested to me but I can't remember the name off the top of my head. Whil I'm at it, Ill be doing a complete tune-up. Any suggestion? Products? I'm getting ready to sell the D. The time has come to move on. I don't wanna put any more money into modding it. If I do, I'm stuck with it for life. Ill probably be putting it on eBay in the next upcoming months

No not yet. Something new. Browsing for now. Not only am I going to sell it, but Ill be trading in my 2005 Altima for my wife. It has had emission troubles and tranny problems and it only has 33,000 miles on it. Time for it to go. I had a close friend of mine lose his life in a motorcyle accident where a DUI driver ran a light and side swipped him on his bike. For that reason I'm also selling my 2002 GSXR-1000

I don't know about that but I'd like something that not a lot of people have modded yet. I'd love 26-30 inch wheels, if they weren't 10 grand or more. LOL. I have a lil money but nothing like that. Maybe if I can get another sponsorship. Maybe a new challenger on 24's?

It's either most likely a bad plug or a bad plug wire. Getting it wet at all?
As long as you're moving on to something else, it's RARE to see a super tricked out Gen2. Keep that in mind.

No moisture since the Radiator hose fiasco. Is there any evidence that plugs like NGK or some other platinum plug will work better/worse. I only ask because I had a guy who seemed to know what he was talking about suggest I run a better plug with all the other mods I've done.

You have the same mods I have. I run the 3923s on purpose.
What others don't understand is that our Magnum motors WANT a colder plug. The stocker or all the special 'better' plugs don't deliver that. The 3923s do. Simple. The stocker is one range higher for emissions crap, not for better runabilty.
Change them out each 30,000 miles and all is good.

3923's are fine for that engine.
When you change the plugs, carefully look to see if #1 looks any different from the rest? the exact appearance of the plug can tell you a lot about what's going on in the cylinder.
If that doesn't tell you anything, and the ignition system is perfect (especially the cap and rotor), then it's time for a compression check.
