Make sure there are no leaks into the trunk at the rear of the car. When you drive at higher speeds a vacuum is created at the rear of the car and exhaust tends to fill that void. From there it can enter the trunk. Driving with a window open can make it worse.

2001 ford escape has horrible rubber smell and bad noise


Remove the drive belt on the alternator and see if you can spin the pulley freely. Check for bearing noise or knocks in the alternator . If it is hard to turn then replace the alternator . While the belt is off check all other units and pulleys to see if they turn freely. Now check the drive belt and smell it If it smells of burnt rubber then replace it as it is what the smell is all about.

Our car runs ok but gets a hot smell and a rotten egg smell comes out the exhaust


The smell is your catalytic convertor, depending on the mileage and it's driving habits (in town, or highway) it might be partially clogged. If it's driven mainly in town, and not on the highway it's probably the case. Might have gotten some bad gas or something also, but that will go away if that was the case.

Car died rotton egg smell


Not sure if engine coolant smells like rotten egs when it burns inside the cylinders , but it sounds like you may have blown a head gasket. Coolant and/or oil could be getting inside combustion chamber. Another possibility is that the catyletic converter might have broken up and colapsed onto the screen where it goes into the exhaust. Might give the rotten egg smell and block the exhaust enough to cause backpressure sufficient to cause the engine to run poorly too.
Try putting your palm over the exhaust pipe , if the exhaust is coming out in pulses (pop ,pop,pop) thats normal , if it is just slowly flowing out with no noticable pulses , I would check into the cat converter problem.

Smell Gas


Well korodiver it sound like the carborator was linking and then it leaked so much that no gas was getting to the carborater. The only thing that will fix your problem is just get a clean peice of cloth and push the acclerator and it will open the valves then just wipe out the carborator and it should fix it.

2003 fuel smell


could be an exhaust leak, or a bad gas cap.  gas caps have a vent that allows air to escape from the tank safely, if you notice a depressurizing sound when you take the gas cap off it should be replaced, it's possible that the air is building up in the tank and leaking out somewhere it shouldn't be, in which case this is very unsafe so please be careful if you must drive it this way.
