If it is in fact running horrible, a faulty sensor will trip a code and the engine light would be on. Don;t replace anymore sensors. Stick with the basics and clean the throttle body and MAF, replace the air filter. You also might have a vacuum leak, check all the hoses and connections.

Well,acutely to tell you truth, I have thoroughly clean the throttle body,their is no vacuum leak, every things is in working order,as a matter of fact,I had waste my money by taking the car five other different garage,they can not find no problem (course they ain't gonna say that,they just say "that's the way it runs "),but the only way I can say is that I'm just gonna have to put up with the running,cause finely I took it to this one garage,and he said that I got something so small,that nobody gonna find the sulutoin,cause it run perfect
