I installed br7 plugs and it ran mint for a while. However now at WOT it starts sputtering hard when it comes into full boost. Also when im just crusing around it will randomly sputter but not like crazy. Like 1 sputter every once and a while. Can anyone help me out?

 

close up the plug gap a little

 

Also double check for a boost leak too.

 

check for leaks. you could also check to make sure that the coil packs are connected good. what are the plugs gapped to and what boost level are you at?

 

plugs are gapped to 27-28 around there, and im at 20 psi. I just replaced my throttle body shaft seals thats where my major leak was. Other then that im dumb founded...lol

 

the copper plugs foul out fast. maybe time for plugs. how long you had em?

 

gap down to .22

 

I had the copper for like a little less then 2 weeks. I switched back to iridium and still doin i. Ill try changing the gap c what happens.

 

narrow the gap, and you should be good to go.

 

narrowed the gap to 22 and still doin it. I found boost leaks at the lower and upper intercooler pipe. I think it could be causeing it.

 

You could also try swapping the coils out one by one. I had a coil go bad and luckily had a buddy willing to let me try his coils. I too thought it was a boost leak at first.

 

umm well just to please my friend i did a compression test and i dont think it came out good. 110-#1 / 90-#2 / 125-#3 / 125-#4. What should i be at? and is it my rings or valves how do i know? im pissed
