Pulled all my spark plugs today, and they were all soot black so I cleaned them with a wire brush and some brake cleaner (they are iridiums with less then 10k on them).
I tested my intercooler piping with a homemade boost tester and it wasn't leaking.
Took the car for a drive after resetting the ECU. It started up cold at 2500 RPM and slowly came back down to around 1800. While driving I noticed when the clutch is pushed in the revs bounce from 1000 to 2000 continulously. (An ongoing problem that comes and goes that i've been trying to solve)
Come back to the house and right before I shut it down the MIL and CEL come on. I shut it off thinking that I will have a code that will point me in the right direction. Put my paper clip in and turn the key and my CEL light isn't flashing just on solid with my "SLIP Cont off" light flashing. 30 mins later I try to check the codes and the CEL light is flashing steady telling me there is no codes.
I start looking into my electrical system checking the plugs at the ECU which look fine, they are tight and none of the pins are bent. (The car is pretty much stock)
Upon looking at the large bundle of wires that come through the firewall from the ECU I find this.
There four wires (3 black and red stripe one and 1 thicker black one all spliced into one black and red wire and also another 2 wires spliced into 1 where the blue electrical tape is. That's not standard I'm assuming?
I had a greddy emanage ultimate that I used to have hooked up only for the speed limit removal and speedo adjustment for bigger rims. I disconnected it awhile ago trying to eliminate possible problems while troubleshooting but it wasn't the problem. I'm thinking I could hook it back up and use it to datalog some data to troubleshoot with although I've never used that datalogging part of the EMU, hoping its straight forward.
Anyone have any ideas?
After looking at some electrical diagrams, I'm starting to think I have some grounding problems.
