Hi. I've posted about this in the past and got the suggestion to check the ECU and/or to listen to what is happening when it idles. the latter is clearly out of the question considering it stalls literally everytime the revs fall. it starts absolutely fine, bucks when driving, requires a good deal of gas when starting from a stop, has an audible valve opening/closing very rapidly sound when bucking, car smoothes somewhat when the opening/closing stops (process repeats). Things i've done: changed fuel filter, plugs, wires, oil pump seal, PCV valve, O2 sensor, rotor and cap, etc. i'll try to remember more later. i have checked the ECU and all it is doing (with the green test mode connector together and the white single prong connector together next to it in the engine compartment on the drivers side) is flash five times quickly then pause, flash five times quickly then pause, over and over again. PLEASE HELP ME!!! if any of the guys who live on NE Kill. in PDX see this i live just up the road from you. I have no money to take it to a shop. thanks all. extremely frustrated, ben
