i got a ls 2001 v8 with 200k miles, i pulled the codes and i had 4 bad coils so i decided to replace all 8 coils and get a all new spark plugs, so after we replaced all the coils i still had a issue with coil 3, we replaced the coil and spark plugs with coil number 2 and still had same issue with coil number 3, so the issue is not the new coil or spark plug, the only thing i can think of is possibly the fuel injector needs to be replaced. any ideas. also when i got the car the check engine light never comes up the bulb may have been removed by the previus owner so i need to know what type of bulb the LS uses so i can replace i went to autozone and they dont have on file the bulb. does any one know? any help will be apprecieted.
