Had multiple cylinders misfiring changed plugs (bosch 2x) and problem persisted. Bought 12 bosch wires part# 09848 from autohausaz and issue was resolved, however i noticed that on the box the wires came in it clearly states that "this product is for use on american and japanese vehicles only” so far everything is working fine. Anyone have any thoughts in this? Also i accidentally filled up my gas tank this morning with 87 gas (I been driving the wifes car and hers uses 87) ...is this a cause for concern? So far the car is driving perfectly

for the spark plugs i'd get some original ones from the stealership because eventually your coils are gonna go bad because most spark plugs that you buy from anywhere out there have resistors, if you car has coils and you put spark plugs with resistors that will end up frying your coils
and for the fuel situation, i wouldnt worry much about it... try adding some premium gas in it.

Thanks for the reply man, I didn't know about the resistors, this is the first I hear about it. Everything is still working fine so I think I'll just leave it alone I will ask the guy at the part store if the plugs he gave me have resistors. At this point though I'd honestly rather deal with changing the coils than remove and install new plus lol it wasn't really that easy of a job hAha
