Why do your 2000 Mercury Mountaineer smells like something is burning sometimes?

Many times the problem is a valve cover gasket(s) that has leaked oil onto the hot exhaust manifold underneath it. When you have stopped in traffic, or if you are on a hill, etc., the oil that has leaked has a chance to run down on the hot manifold and smells like rubber or oil burning. Most of the time this is just a nuisance but it should be repaired if is bad enough to the point you can smell it in your car or truck.

I have a 1995 Mazda 626, I have a similar problem. It dies right at 15 seconds after I hit the gas and remain at 3500 RPM, and I can hardly get up a hill. I have already changed the fuel pump, the injectors were fine, the O2 sensors were fine, changed the air filter, no clogs in the fuel delivery system (yes changed the fuel filter too), changed the plugs and wires, changed the fuel regulator... the only thing left is the catalytic converter is plugged... it's as if my car has asthma, so I'm looking at the Throttle position sensor. Will keep you updated.

I have this cutting out problem and i think Ive managed to diagnose mine to a faulty fuel pump as you can sometimes hear it activate but when you don't the car does not start. but anyway this is what i tried. fortunately my sister has same cars as me, maybe some of these will help you diagnose your problem.

Could old coolant cause a car to smell like a dead animal?

I don't think so. Probably your cabin air filter is dirty or the air duct is partially clogged with old leaves and decomposing stuff - that's what happens to me. It might even be a dead animal that crawled up into the engine and died! Anyway, I keep my cabin air filter changed and I use some of the recipes from the following webpage to keep the inside of the car smelling good.

1999 Olds Intrigue 3.5 When you start your car after sitting 10-15 minutes it starts like it is flooded I do not smell gas at the engine but rich exhaust fumes What would cause this?

I have seen this problem before. It sounds like it could be the fuel pressure regulator. They are typically located on the fuel rail. If your car is blowing black smoke and missing and is hard to start, that is a good indication that it might be the problem. You can test this by getting a fuel pressure tester and hooking it to the fuel port on the fuel rail. Turn on the key (do not start) and it will build pressure. If the pressure drops off, it may be the fuel pressure regulator. It's a cheap and simple fix. A vacuum line and a bolt is all that holds them in.

How do you remove dog smells from a car?

Other than getting it professionally detailed, you can rent a carpet/upholstery cleaner, purchase a soap used for pet ordors. If the ordors are not so bad, Fabreeze* works pretty good. If you transport your dog in your car and want to protect the interior from ordors, put down a large towel or blanket before allowing him to ride.

You probably have an oil leak somewhere around the top of the engine. Valve cover gasket, leaking head gasket. When the engine warms up, it cooks it off and you smell it. http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info
