car runs fine for 20-30 minutes and then starts missing and throwing the multiple random mis fire code. I've replaced the plugs and still does the same thing. how do i go about checking to make sure the coils are still good? it has 114,000 miles on it.

 

whew

I thought missing as in stoken or lost...was like how the eff does your max go missing? it ain't a dog, it don't run away...


Did you replace the plugs with the proper ones? NGK Platinums? Next stop is ignition coils.

 

yes they were replaced with ngk platinum at this point i wish this thing would go missing.

 

You can test the coils but even if one tests good it can still be bad. I'd just buy a used set and replace all of them.

 

where do i find a used set at? cuz 66-90 bucks a coil is crazy.

 

Well you have to pay the cost you own a A34 .

 

could it be a bad injector?

 

Cant you read the codes?

 

So the car finally gave me a specific cylinder that was miss firing after swapping the coil from 4 to 2 I was hoping number two cylinder would start missfiring,but it didn't unplugged number 4 injector and car did change how it was running so looks like its a dead injector.
