    Hi Guys,

    got an issue with my stock 1991 sr20det 180sx
    its been swapped from another shell

    tried starting it starts for abit then dies after 5 seconds. it fires first time but feels like it runs out of air.

    tried starting it without a intercooler hose on so the intercooler was open to the air
    and it starts and runs pretty well just abit rich

    what is the issue here ?
    the intake pipe sucks like crazy to the throttle.

    afm works and runs on my other car
    new iacv tested
    clean manifolds/ throttle body
    tps tested and set.45

    could the afm be restricted as i extended the pipe for better position.
    vac lines not done correctly

    any help would be appreciated
    thanks,
    Matt

    any blockage on the IC by any chance? like rags used to prevent IC from getting dust previosly but forgotten there(believe it i saw that before)

    have you seen the engine running good before?
