my stage three tune i belieive fouls my plugs....they are one step colder ngk's the car will sputter to a halt wont start for about ten min then will be ok for a little while ANY SUGGESTIONS???

should i switch to 2 step colder? will it hurt my engine?

 

Which stage 3 tune? GM, ZZP, etc.?

 

that isnt your plugs man, that sounds like MAF or throttle body issues, please check and clean

 

ZZP stage three tune on a 2.7 pulley

 

one steps are fine. Go to autozone and get some MAF cleaner and throttle body cleaner. Clean those two and see if the problem persists. If it does, move on to replacing plug wires. Also, when it starts sputtering like that, get to an autozone or advanced and have them see if ur throwing any codes that aren't causing ur engine light to come on.

Btw...have you even pulled ur plugs to see if they're fouled out or are you just guessing that's what it is because of the way the car is acting?

i replaced the plugs one time when i did this and it didnt do it again until a thousand or so miles later it doesnt do this all the time just sometimes when it does it again ill get the codes up on here

 

If it's just sometimes, that doesn't sound like fouling out plugs to me. That sounds more like a coil giving out or a bad wire. My fiance's SRT would do silly **** like that....sometimes it would run like a monster and other times it would misfire and drive like crap. Turned out to be a bad wire....
