what's up fellas i got a 99 tl about 4 months ago the car was running fine till today im coming back from work i felt like the car hesitated a little im thinking could it be my plugs i still havent changed them and the car now has 115,000 miles please help thank's

 

just once it did it or it does it constantly? any rough idle? any check engine light?

 

yea just one's,no check engine i was doing about 70 mph

 

If the plugs have never been replaced id recomend replacing them.

But if its only done it once, id just keep a eye on it and see if it does it again. If it were the plugs they should be causing it constantly.

(but id still recomend changing the plugs)

 

thank's
