Ok... I just learned something about this heater element today.
Yesterday, I installed the Radium OCC and to remove this element to connect some AN fittings. I put it back on the rear intake and notice that the wire connecting to it got kinked and was less lengthy and it BARELY could connect to the heater element. I forced it to connect and left the wire all tense and called it a day.
Today, I started my engine and was warming up, I decided to do a MHD diagnostic code test. I also noticed that the car ran rough...almost like it was about to misfire. Lo and behold... the MHD code test showed me these errors:
2C2C - DME: Oxygen sensor 2 before catalytic converter: System check.
2C3E - DME: Oxygen sensor 2 before catalytic converter: Line fault.
2C7F - DME: Lambda control 2.
2CAB - DME: Oxygen sensor 2 before catalytic converter: Temperature.
So...now I am totally confused and start to do the typical mental replay of engine parts that I touched last night. I could only remember the one thing that was different... the super taught wire connection of the heater element...nothing else was changed.
So I get home, smelling tons of fuel, like it was running rich. Open the hood and immediately get to work.
Took out the wire, rerouted in order to get more length. Re-installed the connection to the heater element without any tension. Went for a long ass test drive using all kinds of driving styles... and car ran perfect.
SO... I theorize that if this heater element connector is not good, the DME will give you those errors above and your car will run rough and rich. I went ahead and ordered a new heater element (this small part is damn expensive for what it is, like almost $200 bucks). I got a new one because 1. I am insane and 2. I am OCD and I have a nagging fear that the current cracked connector on my heater element is going to bite me in the ass sooner or later.
That is all.
