Need advise changing ignition coils and plugs
My car has been miss fireing for some time now but not throwing a code so I decided to just change all my coils and plugs all together (80,000 miles). Do I need to disconnect the battery? And if I do is there any kind of procedure to reconnecting it again? I though I saw a post on here about resetting the computers or something... Any other tips would be appreciated as I havent done this yet but it looks fairly easy. Thanks, pat.
Oh, and also... Would aftermarket coils void my powertrain warantee?
