Hi, I have a 2004 Hyundai Elantra (stick shift) with about 104k on it. Was running absolutely great till about a month ago when I noticed that it was beginning to accelerate quite slowly. If I pushed it and got the RPMs up really high it would still pick up, but still not great performance. Also after pushing it a little hard there was a faint burning or smoke smell. Note, once it is up to speed say 60 or 70 it has no trouble maintaining such speeds. It just takes a while getting up to them. And if I really need to step on it the RPMs sky rocket with no real immediate increase in speed. Anyone have any ideas?! Any and all would be appreciated. ---

Given the classic symptoms (high RPMs/poor acceleration, a burning smell), this is almost surely a case of a badly-slipping, worn-out clutch. I strongly suggest that you get the car to a mechanic a.s.a.p., before you turn a straightforward clutch replacement into a much more expensive and extensive repair job. ---

Could that be in anyway related to my clutch master cylinder going out a couple months ago? I replaced it myself and everything seemed to be fine. Thanks! ---

It’s possible there’s some adjustment that needed to be done when the master cylinder was replaced. It’s a good idea to replace the slave too. Still need to take it to a mechanic. ---

Yep, you should have adjusted the slave cylinder , When you were pushing the engine to high RPM and was gaining speed slowly, you were burning the clutch. Peobably too late now. ---

Hi, I have an 04 elantra gt 5 speed. Is the clutch pedal high? Also there is no adjustment on the elantra slave cylinder. Get this to a garage asap have it checked.
