What causes a blinking check engine light and engine misfire after rain on a Ford Windstar?
The keyword in this question is rain...
Water and the engine electrical system just do not 'mix'.
A few pieces of the puzzle to start...
- The flashing check engine light (CEL) indicates the engine computer has detected the engine is misfiring - and lots of it. You should be feeling the engine struggling to run and 'stuttering'.
- Electrical basics:
- The coil generates a high-power electric charge
- The sparkplug wires carries that charge to the sparkplug
Sidebar: The computer (PCM) times the electrical charge to get to the sparkplug at just the perfect time when the air/fuel in the cylinder is ready to fire - The electrical charge enters the sparkplug and ignites the air/fuel into a controlled explosion (of energy).
- Electricity will take the path-of-least-resistance,especially if there is water/moisture to travel along
If there is any weakness or flaw in the connections between the sparkplug wires and the coil, or, at the other end at the sparkplug, the electrical charge is going to escape, or take a detour and not make it all the way sparkplug!
So in this case, focus your efforts on finding where the electric charge / 'spark' is escaping:
- Replace sparkplug wires - chances are yours are original and about 10 years old. They've done their job and time to retire them.
Might as well do the sparkplugs while you're in there. - Inspect the coil for any signs of cracks or breaks / flaws in the surface.
Electricity often leaves a light gray-colored track on the surface of the coil - a good indicator of leaking at the wire/coil connection point.
See "Related Questions" below for very detailed instructions/information on replacing plugs, wires, coil and firing orders and more.
Cylinder 4 misfire on 2003 Montana?
Answer
Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another.
Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings
Answer
this could be anything to do with the cylinder on your car. The plug, the wire, the cap, or the coil (whichever you have.) your best bet is to do a tune up on thecar and do all the plugs, wires, cap, and rotor. if you have a coil pack, try to change those. this is all i can say for now. if that doesn't work, ask the question again and give a little more detail on how the car is acting.
Technically speaking, cylinders do not "misfire": the spark plug causes a spark which causes the fuel to ignite which moves the cylinder, so it is the spark plug that may misfire. Given that, motor vehicle spark plugs may misfire due to any of a number of reasons, including watered-down or low-grade fuel, old and/or dirty oil, fouled spark plugs, clogged cylinders, insufficient oxygen to the plugs, poorly aligned cylinders, et al.
What does it mean to have a flashing security light on a 1997 Nissan Pathfinder?
A flashing CEL light means that the computer has detected a pattern of misfires that's serious enough to damage the catalytic converter (a $1,200 part). You should stop driving the vehicle and get it to a shop immediately. It will not get better on its own and continued driving will not only damage the cat converter, but plug it up to the point where you won't be able to drive the vehicle anymore.

What does it mean if the engine light comes on in a 1995 Nissan Sentra 200 SE-R?
If it is a 1995 200SX SE-R it should NOT give a 402 error code. Nissans up to 1995 did not report 402. 1996 to 1998, error code "0402" indicates a problem to the "Fuel temperature sensor or circuit". Check sentra.net for a list of pertinent error codes. Chris
How do you check the petrol gauge on a 1998 petrol peugeot 306?
Fill up with diesel and see if the gauge still goes up.
The sender unit is under the back seat, one to the left under 6" black plastic plug is the fuel pump, the one to the right is the sender unit. Prise the plug out of the floor and unscrew the the sender unit from tank. Once out it can be moved manually while the ignition is on and see the gauge moving. The float arm is stiff and am still truying to work out why as 3 others checked were all the same. To get at the dash gauge remove the steering wheel, instrument shroud and instrument panel, not a lot to see as all printed circuits.
I would suspect a faulty VSS. Try replacing the vehicle speed sensor in the transmission.
