    hi guys, a couple of weeks ago i thought id give the car a birthday, so i changed the plugs and drive belt and tensioner pully but ever since then she has had problems. It started out the misfire was every now and then and go away for a few days, it started getting worse last week and it started to stall but ended up being able to restart it straight away no problems. But now if it stalls it wont start at all, i took the aircleaner out and hey presto it started again but soon stalled again and that was it. I have changed all the coils and didnt fix it, i know its not the fuel pump as this was replaced not long ago, i also took the line off after the fuel filter and plenty of fuel got pumped out when i turned the ignition on. Im going to change the DFI on it shortly to see how it goes but im not holding my breath. any ideas would be greatly apreciated

    You may have damaged one or more plug leads when you changed the plugs....have a look at the engine running at night when it's really dark and look for sparking. If a lead gets damaged, it puts an extra load on the coils so can make them fail as well. Double check the leads are pressed fully home on the plugs - spray inside the connector with WD40 to let the connector slide on the plug easily.
