    its different than an exhaust smell , maybe gas fumes, and its shaking in gear and out of gear and i also can tell that when i press the gas im not getting the power that i used to

    What is the smell? Is it like burning oil, or gas fumes, or just really strong exhaust fumes?

    So you're saying it only shakes when it's in gear?

Sounds like a dead spark plug or faulty plug wire.

Coolant low, steam out of exhaust, and rough idle at start,


Hate to tell you this bud but you have a head problem most definitely
Head gasket is blown or maybe even a cracked head
Bad news is most caddy engines have problems with head bolts upon removal
I would be looking for a used engine

Engine management light has come on the car is jusddering and the engine smells hot


Check your catalytic convertor. If it starts to clog up your exhaust has a hard time getting out the tailpipe..Your motor will run hot. Your motor will run hotter than normal... And it will make your car shake...Better get it checked. Very bad for your car...Can catch on fire...That catalytic converter will glow red under your car and catch the grass on fire easily

Loud clunking noise


yes you can have a bearing going out of a pulley,as far as you smelling oil burning you could have a valve cover leaking onto the exhaust manifold.

My 2008 dodge grand caravan oil looks like lowfat light chocolate milk?


with 15 years experince as a mechanic it sounds to me that you have a blown head gasket that would result in antifreeze leaking into the oil system. which will cause what they call the choclate milkshake. the funny exhaust smell and white colored smoke is caused from the head gasket leaking coolant into the combustion chamber and when coolant gets into the combustion chamber it burns the coolant and forms a white smoke out of the exhaust that will have a sweet smell. replacing the head gasket and having the cylinder head checked at a machine shop will solve your problem. if you remove the spark plugs one at a time you will probally find one that is wet with a unusual color or may even find two spark plugs that way indicating head gasket blown between two cylinders which is most likely your problem. if not fixed soon driving will cause crankshaft bearing damage which results in engine lock up or crankshaft parts like a piston rod to start to knock or fly apart ruining your engine. i hope this helps you

Lacking power, funny smell near exhaust and sputters and feels like it is going to stall when stopping for a red light.


Rotten egg smell is usually a bad converter. sweet smell is antifreeze meaning blown head gasket or worse.

My "Check Engine Light" has gone on periodically


From what you are describing i feel you might be having an bad EGR valve..It only causes the rough idle and shaking and fuel smell in exhaust..It can also cause back firing. Does it happen? Also do you hear any popping noise from exhaust?

Noise ... raddle


When the engine is cold, go under the car and try to shake the exhaust system at the approximate spot you hear the rattle coming from. It is most likely a heat shield for the exhaust, or a broken (rusted through) hanger for the exhaust making the noise you describe. You can probably correct it with a wire or couple of screws to secure the shield, or replace a hanger.

Rattling noise in rear


could be coming from 3 spots
1 engine mounts = mounts go bad try shaking the motor when its cold to see if you can hear it
2 brakes = sometimes brake hardware can come loose or rust away mo so in brake drums in the back
3 exhaust shield = there is a thin shield around parts of the exhaust while it cold shake the tail pipe to see if you hear it
