I own a 2000 model hyundai accent, automatic. I have had it for twelve months and it has spent 6 months in and out of the mechanics. Its problem is when it has a full tank of fuel it shudders and stalls, it is very chunky to drive and has no pick up when you first excellerate you have to pump the excellarator at least twice to get it to move and when it does move it is very sluggish. Has trouble making it up hills. The car runs a bit better on less than half a tank of fuel and I have noticed it goes a bit better when it has been washed or it is raining. I have had a new O2 sensor put on it, a new alternator, new battery, new fuel filter, air filter, fuel pump, full new exhaust system (2inch sports, with extractors)including the catalic convertor, spark plugs. The fuel injectors have been cleaned several times and yet the problem is still yet to be diagnosed. The car has been taken to several mechanics as well as hyundai and is still running like a junker! PLEASE HELP.
