Hows it goin?
getting a bit of trouble with a ph1 19 16v,bought it a few years ago as a project but never had time till now to work on it.it used to run fine when id start it every couple of weeks.then about a month ago i started it and it ran very rough,like it was only goin on 3 cylinders. it would start & run fine for 2 secs,then start spluttering and roughly idle at about 5-600 rpm for about 5-10 secs and cut out.it wouldnt take any throttle unless i kept flooring it & leting it off quickly.even then it wouldnt rev over 1500 rpm.i pulled my ph2 up beside it and swapped as many parts as i could to see what the problem but it stayed the same.parts i swapped were,coil, MAP sensor, plug leads,idle control valve,throttle sensor,fuel pump relay. i tried the ph1 ECU on the ph2 and it ran fine.one thing i did notice was the idle control valve hummed when the ignition was switched on.with all its original parts back on it was pot luck if it started each time i tried until it got to the stage it wouldnt start at all.tried the ph1 ecu on the ph2 again and it wouldnt start it.opened the ECU and found a burnt diode.Im wondering if anyone else has had the same problems?il get the ECU repaired but dont want to put it back on the car till i find out wot causeing the problem.thanks for any help
