Studdering during acceleration...

[325rye]

I have a 92 325i, a couple of weeks ago my car started missing under acceleration and popping noises back through the throttle body, during idle it misses very little (but can be heard) if Im not accelerating hard i.e.(if my mpg gauge is above 15) It runs like a dream, so highways arent a big problem after I get going...I have changed the O2 sensor and sparkplugs, I have cleaned out the ICV, and checked all the vaccum hoses that I can, and run nothing but 93 octane fuel...please help...if I try anything else and it doesnt work or does Ill post it....

Get It Diagnosed Could Be Throttle Position, Idle Controll Valve, Fuel Filter, Air Filter, Plugedup Catalytic Converter Injectors. Good Luck

I finally fixed it, after going through all the wires going to the coil packs, ICV, O2 sensor, checking fault codes, checking DME for corrosion, many disassemblys of the intake, and my monotonous search for "the bad vacuum hose", and fuel filter struggles.....It was the Bosch Platinum 2 spark plugs....It had them in it when I got it and when this problem first arose, so what did I do to try to fix it but buy new Bosch Platinum 2s a little after that is when the problem just became an all the time thing...Today I put in some Champion RC9YC Copper Plus and my car runs better than when I bought it.... ..... .....
