Hi
Does this model have an EGR Valve, if so then this will most likely be the cause, the "exhaust gas recycler" valve puts any unburnt fuel back into the engine as these start to fail they just push it out of the back of the car hence the smog build up. Get this checked at a garage normally when they go they power of the car is affected but not always.

Regards
Dan

Engine does not shut off when u turn ignition off unless you kick it in reverse


Does it run rough and rattle? If so, carbon deposits are causing engine to "deisel" or "run on". This is also caused by incorrect ignition timing or bad spark plugs.

Engine runs rough intermittently on the highway


Check:
- Fuel filter for clogged.
- Check fuel pump pressure.
- Clean Mass Air Flow sensor with contact cleaner.
- Atmospheric Non Return Vent valve located near the fuel tank.
- Pull up error codes, if any.

1992 continental, car hesitates while driving, has raw fuel smell in cab, replaced coil and wires, new fuel filter, good fuel but still does the same. 3.8 engine. put pan down but no leaks.


This may or may not fix the car but here is a list of things that should help you out:

1 - go to Radio Shack and get a spray can of electrical contact cleaner. Unplug all the electrical connectors underhood, spray them with the cleaner, allow them to air-dry for 20 minutes or so, and plug them back in.

2 - change the spark plugs

3 - get two cans of Seafoam at the auto parts store. Pour one can in the gas tank and fill up on top of it. Pour half of the second can in the oil, and change the oil and filter about 100 miles later. Pour the other half into a coffee mug (one you don't plan to reuse) and get a few feet of vacuum or fuel hose at the parts store. Unplug a vacuum line from the intake manifold (shouldn't matter which one, as long as you can feel suction either on the hose or on the manifold nipple it was attached to, when the car is running). Start the car, and use the vacuum line to **** the Seafoam up into the engine. You'll want a second person in the car, holding it at about 2000 RPM (it'll want to buck and stall as it sucks up the Seafoam). Once it's been sucked up, let it run for another 10 seconds, then shut it down for 15 minutes so it can soak inside the vacuum system of the engine (this is to break down carbon deposits). After that time, start the car. It'll smoke like crazy and may run rough for a few seconds - this is normal and will stop shortly. Let it keep running for 30 minutes or so, revving it up here and there. The smoke will eventually dissipate.

By putting the Seafoam into the oil, you break down sludge in the oiling system. 100 miles of driving is more than enough for it to do its job. Change the oil and filter afterward so you're running on fresh oil. By putting it in the gas tank, you take moisture/condensation out of the fuel system, you'll clean the lines and pump, clean the injectors, and even break down carbon deposits on the valves and in the domes of the combustion chambers. By sucking it into the vacuum system via the manifold, you allow it to circulate throughout the "air" portions of the engine, breaking down carbon and combustion deposits that could be causing your rough running.

Hope it helps!

Plugs have oil deposits on them, car isn't running smooth


U engine most likely need new piston rings, the fuel filter will not cause any type of deposit on the spark plugs How many miles, how much oil does it use in lets say 1000 miles?

Unleaded in Deisel (ahhhhhhh)


The motor is probably ok,empty the fuel tank, change the fuel filters,and drain the fuel lines.Engine may need to be run several miles before feeling normal.
