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

'''RXGhost:''' <small>(2010-02-22 20:46:54)</small>

you run codes by pulling the ECU down and rotating the diag/idle screw

check the factory service manual on how to read codes
