My Teg is running very rich (heavy smell of fuel when car starts/idles and bigger than normal puff of black smoke during hard acceleration) and now when I start my car, I notice a little bit of white smoke coming out the exhaust 
before I spend more money on goodies for my car, I want to get it back to running normal.
Any help is appreciated. TIA

sounds like the valve seals are going bad
that might cause u to be leaking oil into the cylinders
if youre running rich and dont have fpr it might be your o2 sensors going bad

that’s pretty much what I figured.
also, I failed to mention that the white smoke appeared after using up a gas tank w/ STP Fuel Injector Cleaner (used it bc a while back, another member stated it work fine for him, guess not for me 
) anyways, I’m on my 3rd tank of gas after using the cleaner and my car is feeling weak compared to how it was prior to the injector cleaner :sad:
I’m having the same problem in my 92 LS, was looking for a cause, thanks for the help relentlessg2.
