check ignition modgle,sounds like it is bad.what do you mean buy blowing bank 6 plug,any scan that reads a bank 1,2 so on is bad oxygen sensor,you would have 3 of them not 6,if you talking about # 6 plug wire,make sure it is not on manafold burning it.really need to know what you mean.

sorry, coil cylinder #6 missfire changed, the coil and a new spark plug....it lasted 1 day, so next day( 3rd day) i changed the hole driver side coils and spark plugs. so now it sounds like the same thing wich made me changed the coil and the spark plug in the first place,..,add in turning off now to the mix after i changed all the driver sides (sh..t) listed above. So all i really did was put in all new coils n sparkplugs (keept the shake) and made it randomlly turn off here and there as an add on to my problem. . what can cause the coil and the spark plug to go at the same time...i dont have a load tester to chek new coil so i replaced it on the (3rd day) wen i changed all the ones on the driver side....hope that helps u help me more .....the turning off started after the 3rd time i changed all the coil and S-plug on driver side

still sounds like the modgle,this may sound stupid but it could be a cloged cat converter,building up back pressure and heat.

ok...now first : how do i check the module n repair ir...or have to replace..if so does it have to be new or would a used one conflict with the vehicles setings as far as OEM set up, would I need to re-set up...or does it selfe set..? second: would driling a small hole i the cat help stable the back presure do more harm then good..with time would just get bigger ..just starting to sounds to me like its gona get more expensive than im ready for..!

autozone can check the module,yes a second hand one will work,no it wont affect nothing,to remove it you will need a 5.5 metric socket,to remove 2 bolts.yes drill a small hole in down pipe befor cat converter. you can get a aftermarket cat con for about 70 bucks,or if you live in a state that does not do the emission test,take it off and gut it,replace.just dont let anybody see you do it or tell you did it.
