my car misses when on boost
 

at around 5k rpm my car starts to missfire
checked the plugs and they seem ok
all tan colored

could it be bad gas or time to get new plug wires

i think its both as i havent changed the plus wires since i got the car 2 years ago

Re:my car misses when on boost
 

are the plugs gapped properly? try dropping the gap size by 0.005"

i was just about to say that.....check if your gap is too big. you may need to make the gap smaller to like .032 or so.
