Check the valve covers for small leaks, the oil will run down onto the exhaust manifold and this causes the burning smell. Oil leaks on this model and engine is a very common issue.

SOURCE: 96 Ford truck engine lIght will not go away.

this is the problem with code readers they bwill tell you the code and sometimes even have a reset feature. However they do not tell you the parameters and don't have an drivability feature so you can not test the ecm and all the sensors or modules while engine is running. diagnostic scan tools are very expensive and hard to use unless you have been trained to do so and PEP BOYs is not what I call real reliable mechanics to begin with. Now I concure with toddG on his reasoning in what might be the potential fault. if your vehicle is running rich or lean your O2 sensor will pick this up on the exaust side, however it is not the sole sensor responsible for the ecm adjusting the fuel air mixture.. you stated that you have switched out several o2 sensors and the fuel pressure regulator, but there is also you mass air flow sensor, your TPS sensor, as well as your map sensor these are worth checking out and just because a faulty sensor is the problem doesn't mean you will get a code each time. the system is built with redundancy in order to keep the vehicle running. in order to get the best possible diagnois take it to a shop where they have a full diagnostic scanner this will have not only OBD1 and OBD2 but cam protocol as well. while the tech is scanning the vehicle he will be able to see how the engine is performing under realtime conditions. please rate this as well as change the rating for toddg because he did offer a valid suggestion

It's most likely the rear cam seals (o-rings) which is a pretty simply DIY, especially on the 3.5L model. The o-ring is only about $5.00 from the dealer (each, you need one for each side).

SOURCE: Engine smells like rubber burning

Generally that smell is caused by an oil leak that is getting on either the exhaust pipe or manifold (doesn't take much to smell). As far as bottle getting low, I've got a 93 that never stays full but only needs coolant in the radiator about once every two months. Been like that for two or three years and has never overheated. I'm sure there is a small leak somewhere, but I'm not driving myself crazy looking for it. Check all hose connections, and look on the ground after being parked overnight...If it's leaking, something will show up. But if the radiator is staying full, just check it when checking oil level.

Sounds like there is a blown piston, to be sure have a compression test done on that #2 cylinder, if the reading is low, then you'll know.
A friend of mine had a 95 that did simular things only a little more,
it started smoking, dash lights flickered, etc. Finally, he had to get rid of it, the piston rod went through the engine block.

Why does my van have a burning smell when I go up hills?


You may have a minor oil leak and not see any dripping on the ground. The van is under load going up hills and will run slightly hotter. If there is oil leaking in or around the exhaust manifold it will give a burning smell.

Engine died burning smell


If the smell is like burning oil or really hot coolant. you may have killed the motor. If it smells like burning plastic ,look for shorthing wires around the exhaust manifold battery, alternator or place that a wire could be burnt. If a rubber smell check for belt failure.

Burnt Oil Smell


Check carefully around the valve covers, this is the area that leaks most frequently occur, and being located next to the exhaust manifold can easily cause the burning smell. There is a very easy to replace gasket under the cover. Other possibilities, shop or you when changed or added oil spilled a bit and that has worked down to the exhaust manifold and is causing the burnt oil smell. Last possibility is that you do have a slow leak on the underside of the engine that is blowing back onto the exhaust system causing the smell.

Lack of power


is the trans fluid level ok? check the color of the fluid, should be a nice cherry red color, and notice the smell of the fluid. if it smells burnt, or like the smell of burned brakes. if you have the bad smell, the clutches are burning, time to rebuild.

Burning smell


The sulphur smell is the result of the emmisions control system. I have an 06 Expedition with the exact same engine and emmisions system as yours. When the engine is cold, you don't smell that sulphur smell, but as soon as the engine gets to operating temperature, the exhaust gasses smell sulphury. Nothing wrong with your ride - they all do that. The dealership sometimes spray the underbody with some type of rubber to protect the vehicle against rust. This rubber stuff sometimes get sprayd on the exhaust as well and then you will smell "burning tires" after driving the vehicle. This will go away after a few thousend miles though.
