after numerous fixes to my car an underlying issue has come to light on my car perhaps anybody could shed some light:
After changing the coil, leads and plugs i can 100% vouch for each cylinder getting spark however ive noticed on cylinder 4 it doesn't make a difference to the engines running if the ignition lead is plugged in from the coil or not, if you unplug any of the other 3 leads it runs like a complete pig, ive tested the lead with the plug still in and it archs when running so i know its not a spark issue, if i unplug the injector harness from the injector it also makes no difference to the running apart from throwing up a check light if tried on any other injector by unplugging the harness from it it will also run like a pig so that would leave me to believe if was a fuel/injector issue?? would that sound right?
