HELP PLEASE! poor idle and no response bogged down

[JoshuaKaiser]

i have a 93 240sx se and it idles rough and when you floor it it will not respond at all. If you slowly push on the gas it will run but bogged down a lot at about 50% power. I changed the MAF sensor today and that did not fix the issue. I appreciate any ideas..this is my daily and i have got to get this fixed. THANKS-Josh

can ya tell if your running rich?..ie (too much gas)..if so..it might be injectors..allso..take a look at your intake many seal..and check vacume lines..those things get old and crumble after a while...post back and let us know what ya find.

tps maybe?

Have you tried to see if there are any ecu codes?

will everything kind of die if you rev (softly) to 2500 rpms-ish? i've heard 2500 is the magic number for a bad or disconnected maf sensor. if it doesn't and still runs like crap then you might have a big air leak. check all hoses and couplings, kinda like liquid_cool said.
