Spark plugs $18-20 each vs $100 injector. |
You tease me for throwing parts at it until the codes stopped (which is true), then you recommend OP throw parts at his problem until the codes stop... I wouldn't buy a new spark plug because that's likely not the problem. If you want to validate it's not the spark plug just swap #6 and #1 and see if the misfire follows the plug.
I don't see how you'll get pressure too low when DME is cutting fuel to an injector. I was getting pressure too low because the injector continued to leak fuel into the cylinder AFTER the DME cut fuel. It would also leak when the car was off, which caused the fuel pressure in the rail to drop and throw a pressure too low at start code.
Anyway, run the car for a bit, then pull the spark plug on cylinder 6. Does it have fuel on it? Does it smell like fuel? You need a new injector.
