Losing power - plugs?

[Vipersrule]

How often do you change out the plugs on the Viper? I've got about 4,700 miles on it and just today it seemed a bit sluggish. It idles great, but when I got on it, it just kind of hesitated just a bit. It's never done it before.

I'm guessing a new set of plugs this weekend maybe.

Anyother suggestions?

Change'em out every 10,000 miles. And wires too.

Check the gap. I have been told to use .035 and stock champs. I guess if tehy are gapped to wide, the spark is weak. Plugs could be bad too, just thinking out loud for you.

Well I'm going to try plugs first. East thing to do. It's a really BAD feeling when my Viper just doesn't "punch" like it's suppose to.

I've got to get it fixed!!!!!!

Whats the weather like today where you are?

Most likely you are getting bored of the power you have and just need MORE.

Hard to believe that plugs on a stock engine are bad enough to notice at 4700 miles.
Are both throttle plates opening?

I would check the O2 sensors.

I change my plugs and wires every 20K. Cost about $80.

Maybe some bad gas?

It was 102 degrees. I've run with it this hot before, but it has never "bogged" down on me. It felt really strange.

I am very used to the strong pull on acceleration. It just didn't have it yesterday. Kind of worries me that something may be {dirty, clogged, fowled, etc...}

Yeah - I thought of this one - that might be it. It started after I got gas yesterday. That may be the problem. I'll run it down next week and see what happens.

Does anyone ever use additive in the fuel? If so, recommendations?

3K miles on 95. Should I replace?

How old are they? $80/year isn't going to break you.

Change plugs @ 20k, but they're so cheap, can't hurt to do it early.

Regarding wires, 40k seemed to work fine for me. At around 30k, I noticed I was down on power, so I changed both the plugs and wires, and seemed to notice a boost. However, the wires were the Mopar blue wires, which caused radio static, so I took them off in exchange for my original stock wires that I had just taken off, and I noticed no detrimental effect. I continued to drive with the stock wires to ~40k, changed to new stock wires, and noticed NO difference (even went to the dyno later that morning). Consequently, 40k on Mopar stock wires seemed fine, not sure how much further though.

That's only 2,200!!! I'm putting more than that on my RT/10 next weekend.

Motor City...I'm just busting your balls man...I'm probably a bigger poser than you are!

I know my RT is shinier!!!
