I am one of the types of guys that loves to do his own research. I like to figure it out.. it's sort of a challenge for me. But I can also admit when I need help.

Like the title suggests in an aggressive way, I have a few issues with my 1993 300E:

--Bogging down upon acceleration. Not all the time. And when it "unsticks", it really takes off! The engine is still very strong. It started a little after I bought it in December '08, and started happening more and more. It's worse around a corner (picture the on-ramp to a highway), or when I depress the pedal quickly.

--I have noticed a MASSIVE oil leak that appears to be coming from the very front of the car, and some spillage from right underneath the engine.

--It is also leaking antifreeze in a manic way.

--I just got pulled over today for the amount of white smoke blowing out of the back. This only happens on the highway at speeds greater than 50mph, and it only lasts a few minutes.. maybe 3-5. I've also noticed that it only happens when the car is cold and approaching operating temp; once it reaches that point, there's no more smoke for the rest of the day - provided I keep running errands to keep the engine warm.

--Smoke seepage into the cabin. I haven't pinpointed where it's coming from, but it only happens when the white smoke is blowing out the back, and it has the same characteristics (3-5 mins, cold start, etc..).

--Speaking of starting, when it's cold.. say in the morning - or afternoon depending on the night before - it doesn't want to start right away. I've never been stranded, as it always ends up starting at some point, but I've noticed that when it's completely cold, it has troubles. When the engine is warm, it starts right up.

But no matter what happens, I have the bogging down issue, sputtering, misfiring... SOMETHING... all the live long day.

Thoughts?
