I apologize for the long post but I desperately need help...

So I purchased a 1999 Mercury Mystique in Spring 2009. In January 2010 I got the timing belt repaired with new pulleys and an engine cover and valve cover; later in 2010 I got the fuel filter, throttle position sensor, switch, and clamp repaired; a month later, the exhaust camshaft, and cam sprokets; and then in the fall I repaired the tensioner belt, water pump, serpentine belt tensioner, idler pulley, and I also got new anti freeze, a coolant flush with sealer and conditioner, a pcv valve hose, suppresor spark plug, tuned the electronic ignition, another fuel filter, and a fuel system tune up. After all of that I went to get a simple oil change and was told that the car had a massive oil leak. I got the oil leak fixed, the camshaft sensor, camshaft seal, timing belt repaired (because it had oil all over it) and another valve cover gasket.

After picking the car up, I was almost at my destination when I noticed smoke from the back. It sputtered smoke about 3 times and was hard to accelerate. After letting it sit, it was fine, but then more smoke. Not a continuous smoke but like puffs. It seems to come from underneath the car, not the tailpipe and only when I've driven it a while and when I accelerate. THe smoke smells a bit like burnt rubber, maybe plastic. A week ago I was driving and all of a sudden its hard to accelerate and I see the smoke. I pulled over and let it sit and tried to drive home when a huge trail of smoke comes from behind the car and its making a ticking or pecking sound. The check engine light comes on, the oil light, and battery light comes on and then it just won't move. It had enough power to move to the side of the road. It starts and everything but what could the problem be? I feel like a fool for putting so much money into this car. I've ttried to find out what the problem is by researchig but I'm lost. Any ideas or advice? Thanks!

When it first smoked on the way home I would have taken it back to where the repairs were done. Sounds like a blown seal has caused oil to leak out onto the exhaust system, causing the initial smoke. As the oil leaked more, and became low, you lost top end lubrication. That's the ticking sound. Running that way causes additional problems such as cracked piston rings, spun crankshaft or connecting rod bearings. I would tow it, and not try to drive again. What's showing on the oil dipstick?

I would take the car back (even if had to tow) and demand it be checked and repaired properly!!

Possibly, your catalytic converter broke apart, and particles of it are blocking your exhaust, which would cause acceleration problems. If so, your exhaust system might be overheating, resulting in smoking and the burning of the rubber fittings in the exhaust pipe hangers.

When your exhaust is blocked, it'll keep on starting, as the pressure in the pipes dissipates, but as soon as exhaust pressure starts to bulld up again, it will cut out. But before it gets too bad, it will just retard the acceleration and reduce your maximum speed.

Very good theory!

white smoke = coolant

I agree!

also:

black smoke - fuel system

or something like someone else said, something getting hot underneath and burning... be careful, would not want your car turning into a fireball.

Sounds like you bought a money pit. Have the car towed back to the shop & get it checked out. Sometimes after i have driven my 26 y/o car for a lil bit it omits a burning smell. It has been doing it for yrs.

Thanks everyone! I'll get it towed back to the car shop as soon as possible. Hopefully all goes well...
