Well I looked at the other thread but its not the same symptoms that I'm having. I was getting a code for multiple cylinder misfire. I was still running stock ngk, and thought that going to the bkr6e-11 would help. Well I'm not getting the misfiring code anymore but now there is a lot of hesitation. They are gapped to .040. Any help would be appreciated.

mine are gapped to 0.38 so that shouldnt be the problem, might be an injector or bad coil

 

Well the hesitation wasn't there before the plug change now it is.

 

you might have messed up a coil, make sure they are all plugged in tight. it sounds like some sort of spark issue.

 

Ehh, I went ahead and pulled a plug its lightly coated with white residue. Im going to put the others back in for now. Could this have anything to do with elevation(Im at 6000+ ft)?

 

I don't know how much boost you are running but it might be that your plugs are gapped too large. If I tried to gap my plugs to .040" my car wouldn't go anywhere if I went WOT, mine are gapped at like .032".

 

well as mike knows that when i first did my plugs i gapped them to .036 and they car was bogging and not moving under boost at all, i gapped them to .040 and they worked like a charm, weird i know, si I think .040 should be fine for you.

 

Well the I found out what the problem was....they were to loose. Runs great now.

 

too loose as in they weren't screwed in tightly?

 

yeah I guess i rushed it or just wasnt paying attention.
