I have an 06 ss/sc, I don't know what is going on with it but once it gets warm, I have a serious power loss. I pulled the plugs to see what was going on, and 3 are normal, the other if fouled. I can only come to a couple of guesses. Either I have a bad injector, or there is a bad sensor telling just that cylinder to run rich. It is easy to hear it loading up when I pull away from a stop. Does anyone have any other ideas?

 

are you stock, any mods?

 

There are a couple of mods, but the only thing that might have an effect on air/fuel mixture is CAI, but I am pretty sure that would screw up all 4 cylinders and not just 1. I could be mistaken though, I am still new to the 4 cyl world

 

replace the plugs and see if the next set fouls out.. could have been anoher problem b4 u bought it that was fixed and never replaced plugs... also check to make sure ur intercooler pump is working...take the cap off wheer u fill up the sc h/e and see if its flowing or sittingstill.. a few thereads on this.

 

What plugs are in it? Stock NGK R PFR6T? IF not i would put those in there. Even if the intercooler pump was broken, I dont think it would make it run rich in just one cylinder.

 

swap the coil pack from the fouled hole to another one. See if it follow's . Same can be done with an injector.

 

I went to buy plugs and looked for the ngk s nobody had them, the only think i found were the ngk laser platinum. anyone tried these yet?

 

No. Do not use those.

Normally these have to be special ordered. Most places have the stock heat range, but if they dont. It only takes a day to get there..

Use Copper only.

 

All of the places I went to said they could not get them, autozone, pep boys and napa, what about the autolite iridiums?

 

The NGK R PFR6T-10G is the LASER PLATINUM plug that comes stock in the SS/SC's.

 

^^ I saw iridium the first time i read that... i swear.. lol..

I buy my plugs from autozone, they got them in the same day i ordered them...

With those stores, there is a high chance you are talking to an idiot.

 

Thats the truth lol ,

I was suprised as hell when i saw Gm put platinum's in the SS/SC to begin with , from what people have said platinum's and forced injection isn't the best combo . I've read alot of comments on the web saying copper ----> iridium ------> platinum for F/I .

 

Copper > IX > Platinum is deffinatly the equation.

Its pretty funny when people say "but i wanna spend more than 8 dollars for spark plugs, dont link the shitty ones"....

 

Well, I went and hooked up to the computer, I had 13 codes come up, and know what is going on. Thanks for the ideas
