i put the stock injectors in ,then i took the ones out of my escy in it and the same deal .i do wonder if allen tuned for stock inj or tuned the 60s that were in it bn unaware i was putting stock in.seems to be loading up at idle and then sure enough the cel po300 comes on.i really wonder if my intake tube is too small ,and not giving enough air at idle or not mixing right wen i slow down and stop at a red light .im stumped.im sure its the smallest of things.
