Spray the coil with WD-40 around the lead to the distributor cap. If it runs smooth then, replace the coil. WD-40 displaces moisture. There could be a small crack that you can't see; it closes up when it warms up. Then go back to the distributor cap and take it off; see if there's moisture in there. If so, spray it with starter fluid and leave it sit until it's all dried out. You could use a hair dryer too I suppose. Put it back on and make sure it's seated properly. Did you replace the lead from the coil also? Check the wire ends; have you seated them properly?

Why do the windows on my 2009 caravanfog uponce Istart todrive?The windows will beclear after I warm it up but once I start drive they fog up.I do not smell antifreezeand the heater core lookslikenew.


windows fog up on the inside simply because of the hot breath of the occupants
this heat is cooled by the screen and condenses and so a fog is created
simple physics really - hot moisture + cold air =rain to over come this quickly run the air conditioner ( climate control) and that takes the moisture out of the air in the car and then the windscreen clears
you are going to say that it is too cold for the ac to run well at the same time run the heater until you have a pleasant temperature that is dry ( climate control--when it gets too hot the ac cuts in and when it gets to cold the ac switches off BUT the moisture that causes the fog on the windows is gone )

Why won't my 95 dodge intrepid start after rain or high moisture?


Probably a bad connection or corrosion at connections in wiring. I would start with the ignition system like a coil pack.

Will not start after raining.Takes two to three days of no rain to start again.Then van will run again till it rains again.


you don`t say but it sounds like the moisture from the rain is sitting on the plug wires causing them to short the voltage to ground and possibly moisture in the distributor cap.how long has it been since a tune-up was done to the van.

It has a problem that seams to be caused by moisture if it sits out in the rain and or fog for more than a day. The car will start but will be misfiring and engine will die unless you rev it up to 1,500...


Most likely cause is a crack in the distributor cap. This allows moisture to penetrate the cap and causing misfires and stalling. This would be the 1st place to check.

When it rains or moisture in the air my truck want to shut off


Take the distributer cap off and spray the inside of the cap with wd-40 and wipe clean. If that doesn't work replace the cap. If that doesn't work replace the spark plug wires.

HAVE YOU HAD YOU THROTTLE BODY AND OR YOUR CAM SHAFT SENSOR CHECKED OR YOUR AIR TEMP SENSOR ? IT MOST LIKELY SOUNDS LIKE YOUR AIR TEMP SENSOR IS'NT LETTING ENOUGH AIR IN OR OPENING YOUR MASS AIR FLAP ENOUGH WHEN ITS COLD OUT CAUSING THIS.
