I know exactly what you mean, Gary. Same happened to me (all the lights and gutless run). Well, I took my car in over the weekend and they confirmed to me that the one (new) ignition coil that I replaced was not working at all. The guys at the garage replaced it with another new one. The beauty is running normal again and the smile is back on my face. When you take your car to your mate, ask him to check all the ignition coils. If they are cracked, the spark don't fire straight down. It fires through the cracked which causes the misfiring and the lights flashing on the dash. Because of the overheated engine nearly all of mine cracked, all replaced and she is running smooth.
