by the end of this year I will have to do my 100k tune up. My question is what should I do. I am the only owner, have common sense with cars and working on them , i haven't done anything but oil changes, my car runs almost flawless other then i need a front end alignment. So what do you thik i should do for my 100k tune up? Thanks guys for all suggestions

 

Spray 100 wet shot of n02. If it holds, keep changing your oil and enjoy your car.

If not, Sorry for your loss.










































I was joking please dont do that, Only an idiot like me would do that.

I would say change your air filter, plugs, maybe tranny fluid. I guess it depends on how far you want to go

 

id also check your timing chain...if its still tight dont worry about it...and dont forget your pulley belt

 

^ probably a good idea also

 

you might also want to change out your chain tensioner as well as your belt tensioner...better safe than sorry

 

I would change the Tranny oil , put a fresh set of plugs in her and change the supercharger oil . I would also look at doing all the filters depending on when they were done last ..... If the fuel filter has more than 20K on it ...I would change it.

 

Change ALL the fluids (oil, SC oil if equipped, trans fluid, brake fluid, coolant)

Change spark plugs

change filters(air, fuel if equipped, trans if auto and you dont get a flush)
