my 2k with 49k auto does not seem to idle as smoolthly as when i got it at 25k. i use 94octane. car use to ping and was gonna replace coils but 94 octane stoped pinging and i never had a ses light come on. any sugestions on what i can do.

 

Have you tried the Seafoam treatment? Just did it to mine and idle feels smmoootthhh. I have 57k on mine and it worked for me. Can't say for sure if this will help with yours.

 

Quick question, can you buy that Seafoam at certain stores or do you have to order it online?

 

the only stores I know that have it is Napa and Autozone. then again we don't have mom and pop srores in there.
