just got my tibby about a month ago, it never used to do this and i just noticed it the other day..
when taking off from a stop, if you take off too fast the engine hesitates at first, like the engine chops
wondering what it is...spark plug??
also, the CEL is on, I read the gas cap post and figure that that could be why it's on, but not sure (I lost my gas cap at kwik trip the other day and found a replacement one that the guy at the gas station gave me----it doesn't even click 3 times no matter how hard u turn it. lol)
oh yeah, and if anyone has a oem gas cap they don't want/use, lemme know wink1.gif.

 

ok... the cel is from your gas cap.... the hesitation is because you are putting your foot down and the engine cannot keep up... there isnt anything wrong, its just your engine trying to do too much

 

positive? it's never felt like that before, and i have driven it for almost a month now..it feels like something else.

 

Mine does that every once in awhile. It's almost like it sputters cause it's not getting enough gas, right?

 

mine ALWAYS does it

 

Yup, they do it if you punch the gas too hard. Hyundai likes to program their engines RICH so there aren't any problems. If you want a PERFECT answer for it, get a SAFC>

 

Okay so whoever uses abreviatied forms such as SAFC should put what it really means in brackets after... that would help laugh.gif

 

Check your Wires/Plugs.. I had the CEL on the highway.. took it in, and #4 plug was shot.. changed the plugs and wires.. no prob anymore.

LOL, that is the name brand and if I had to guess I would say it stands for Stand Alone Fuel Control....something like that.
Basically it is an Air/Fuel ratio controller.

 

Nope, Super Air Fuel Control. The SAFC's are piggy-back fuel controllers.
