    running bad - emergency HELP!!!!

    1985 nissan 300zx na 169,xxx manual trans|
    ------------------------------------------


    Runs amazing cold after about 15 - 20 min seems like a miss fire but rpms wont go higher then 3k. speed decreases greatly feels strange like bad gas so flushed the tank new GOOD gas same thing. please input needed asap cant get online much due to getting laid off from work im getting interviews so if possible call me a 1 330 673 1979. names rick someone who might know what this issue is call me asap

    Edit: To explain what it feels like after taking it out a few min ago. sluggish then when stopped cant seem to creep the clutch out of the parking lot wants to stall so clutch in let sit for about 3 min free rev a bit and let loose quick and the movement of the car seems to keep it running but cant leave 3 gear cause its like shes just choking out. :Edit

    i know you can download a pdf of the fsm offline i had it once before but its lost amongst the millions of other fsms that are printed out and laying around my house in boxes. i mean i even have one for a 1987 nissan skyline for the rb20 cause i did an engine swap with my pal one time and we needed it..
