help? my car sounds like a v8 and its bonestock?

I have a 91 hatch with a KA24DE from a 97 kouki and for some reason its been running really rough at idle and it sounds like its got bigger cams and a stroker kit in it but it just runs like crap. under load its fine but I cant find the problem, fuel pressure is alittle high, its not starving for fuel but at idle its running almost 100% lean when we checked it with a gas analyzer. MAF is clean and reading correctly the only thing I can think of is possibly the Throttle Position Sensor, any ideas?
