I have a Hyndai Tiburon 2005 with 32000 miles, manual. Got the oil changed and noticed the same day that when I’m driving within norm rpm for specified gear and giving it gas, the engine drops out and acts doggy! Any ideas?
Is the engine also idling rougher than usual? If so, then I would suspect that someone at the oil change place (I really hope that you did not go to Jiffy Lube or one of its clones) may have disconnected a vacuum hose.
