honestly i've only done #s 2,4,& 6. but so far so good. i had a P1320 with a cyl 4 misfire with changing the plugs and the coils (also the connectors i mention above{tight fit on coil but worked}) managed to get rid of the cyl 4 misfire. still have the P1320 and now a cyl 3 misfire

(go figure). should get to that side maybe tomorrow. weird thing is now i have a pending P0505 code

i did disconnect the IACV sensor a few times when working in that area could it be that i messed it up? what else could cause that? Are the misfire codes and that 505 code connected in any way? does the MAF sensor play any part in all this?
sorry for the rambling. but yeah so far so good with the coils decent price and fit.guess i'll see what happens after changing out the other three.
P.S if you get the connectors you will have to use the metal tabs they come with the oem tabs dont lock in to the new conncetor. the pins on the coil will push them back and not make contact.
