A common mistake to make is assuming a new part can not be defective. I spent a good part of my career working on cars with less than 500 miles on them and they and most of the time it came back to defective parts.

If you think it may be a coil then just switch the coils and see if the error follows. Don't be surprised if its a cracked plug.

 

for future reference, many headers have a coating on the inside that when burned off can mess the 02 sensors up. best to run the old ones for a few days then install new.

 

 

Ok so i replaced coil wires and plugs .still a constant misfire. My buddy said his ecm was going out and was causing his .ive also heard the icm... And advice cause i love my car but this has been constant for months to where my dd is useless

 

Is it still cylinder 6 code? Have you tried swapping coils and fuel injector to see if the error follows anything?

 

No idea how to do an injector but ill swap coils today and try

 

if you havent yet go here and download the factory service/shop manual. http://www.mediafire.com/?40mfgeoe4ctti 2000 svcman will be same as yours.

 

Anyone know if i can get a replacement injector pigtail? Or the part number. Figure out the issue and its in the plug

 

Rock Auto should have them.
