My headlights won't shut off without unplugging the battery, Stereo will not come on, no climate control, had to unplug the horn because it will not shut off, the dome lights will not come on at all, when the door is opened it will not turn the dome lights on or chime like it is suppose to... Every once in a while when it warms up outside everything will work. When I start the car the check engine and battery light will come on and stay on until I hit the gas, headlights stay dim until I hit the gas too and then will brighten up. Idle's low when in drive at stop signs/lights.

I have no aftermarket turbo, however there was a remote start and aftermarket alarm that was installed then removed before I bought it...
Thought I had it fixed a while ago with some relays, now it is back with a vengence...

I love my car and am feeling a bit broken hearted by it's current demise.
