Exhaust color/strange Idle

[Jones, Chris (OD/ORS)]

On Saturday, I was washing my car( 87 4000s,8v 1.8L) letting the car run.
For awhile now a whittish/greyish exhaust fumes color has been coming out
along with this very annoying rattling sound from the engine bay. The oil
level is fine but I still hear this sound. It seems to get louder when the
engine is under a loud (ex. when going up a hill). But now along with
everything my car is shacking like crazy when in drive waiting at a
light(around 850 rpm, but in park it idles at 1050 rpm). I recently add a
custom 2.25" exhaust system, new cap, rotor, bosch wires, platinum plugs,
and oil change). It seems like I am not getting any power until about 3700
rpm, and the automatic tranny is not shifting properly to me. (I am use to a
turbo to much)
