Need help diagnosing...

[dsmeclipsex]

Ok, here's the laundry list:

1) popping feeling and sounds during left hand turns (Feels like CV joint). When driving on the freeway i can hear a slight vibration / click ?

2) slight ticking sound, coming from the rear of the car. Almost sounds like it's coming from the differential, however, when i lightly touch the breaks the ticking stops.

3) Turbo timer turns on and off when using a)headlights b) blinkers. I think it's a ground bleeding through but im not sure. I haven't gone through the wiring to figure it out.

4) Check engine light popped. Went from around 20mpg to 13-14mpg. Car is running pretty rough at this point.

5) Fuel pump hits a high note every once in a while. Like an earpiercing high pitch note.

I haven't been driving the car a whole lot due to all these things completely pissing me off. Working 60 hours a week is killing my wrench-time.

Current mods are in my profile. Could definetly use some outside input. Thanks guys.

well check your cv axel's front and back.
also check your wire's on trubo time to do so just turn the car on mess with the wire to the turbo timer see what it does.
what is your wideband reading on A/F ?
check for vuccume/boost leak's?
If you can shake the front tire's to see if you have any play in the front end.(shake it from right to left,them up and down if you have play try to find it bye the feel of it. ?

As far as i can tell, i don't have any boost leaks. I pretty much went through all the vacs when i bought the car, and i check them pretty often.

Have you made and used a boost leak tester? If not, you could still have a horrible boost leak and it may not be obvious/ visible. An example would be throttle body shaft seals or the injector o-rings.

We don't do laundry lists.
