Misfire Problems Cylider 2

Hi Nick

I had to send my engine ecu to get checked out and the technician told me it had been repaired before. 300.00 later he repaired it, although he did not specifically say that the repair he did was causing my misfire?? However he told me that my ecu fault i had was caused by a circuit that was traveling back to the ecu unit and shorting it out and if I did not track down the electricla fault, the moment i plugged the ecu back in it could blow again. Both my mechanics (so called experts) were unsure of where to start looking for this fault when i told them this.
The story gets better...I managed to speak to a 22 year old mechanic just starting out, who told me to go back to basics and replace all my six injectors and spark plugs before pluggin the ecu back in. At more expense I replaced all six as advised and now the car runs perfect. In all, this exersise has cost me the best part of 800.00 when I beleive all i needed to do in the first place was to replace the six injectors and spark plugs.
I suggest you start with the basics and work from there. Having read through this site I relasised that the combination of faults I refering to was only one main problem. Misfire of Cylinder 2 caused by a dogy injector.
The other codes that were triggered by this fault were just a chain reaction of events that the ecu goes through to try and correct itself. In future if i get any more faults I'll go through my own process of elimination before spending 60.00 per hour for guess work!
I hope you get your problem sorted mate.
