i have an s13 with some issues...i think it was originally a single cam automatic but has been converted to duel cam 5spd...its idling rough and after it warms up it bogs down BAD after about half throttle but only while driving, i can push in the clutch or put it in neutral at any speed and rev it up just fine...any suggestions would be greatly appriciated....like i said it ONLY does it when its warm

Check your fuel system. Pump could be on its way out or injectors are clogged or leaky and need cleaning. Is the gas in it old? Easiest first could be to just get a new fuel filter. Im sure it could use one. Also make sure its timed correctly. My RX-7 did what you are experiencing and it was a combination of pump and injectors.

redo your timing, and check that Maf

do you know how to check for spark, using a screw driver...without shocking the crap out of yourself?

Ill check that and I just put a new fuel filter and gas with lucas oil injector cleaner in it

Unplug MAF. See if it runs any better, you will not be able to rev over 3k but this is to test the MAF. Car goes into limp mode.

Also pull fuel pump check fuel pump sock, if its dark looking replace it. (ended up being my problem)

it might be also the fule pump my brothers s13 was doing the same thing, is going to be the fule system!!!

fuel pump is my next option...i just replaced the fuel filter and am currently running 93 octane with lucas oil injector cleaner and seafoam to try to clean out the fuel system...if that doesnt work imma swap the pump
