    Do you have a distributor cap on your vehicle? To start out with, and do this one at a time, take a plug wire off, put a dab of silicon dielectric grease on each end, and put it back on. If it does have a distributor cap, you could replace it: A cracked distributor cap will seal in moisture, making it misfire a bit. Let me know if you don't have a dizzy, or if this doesn't fix it!

Check engine light flashes and rough idle under wet conditions


Check the ignition system, coil/s, plug wires or boots. Easiest way to find the problem is to take a spray bottle with water and spray them down when the truck is running. When it runs rough, you found the problem.

My ford windstar 2003 hesitates during cold weather or wet conditions. But good during idle. Some time shows blinking engine light.


The flashing and rough running is to to a misfire or misfires cause by arcing due to moisture on ignition components. Eventually these misfires can lead to other problems such as damage catalytic converter. Start by identifying which cylinder(s) is/are misfiring. The arching can be reproduced with a spray bottle filled with soapy water. Spray the ignition components (wires, coils, distributor cap...)and look for the vehicle to idle rough. Replace any faulty component.

5.3 liter Chevy engine #1 Cylinder not firing at idle


My opinion...

Year? Miles?

There's no way I'd dive into a "HEAD GASKET"
diagnosis without pressure testing the cooling
system and (wet/dry) COMPRESSION testing
the whole engine...

Even if it is a "HEAD GASKET"... the entire engine
might be ready for a REFRESH... and tossing a new
Head gasket into a TIRED ENGINE not insubstantial
(a lot of wasted time & money)...

Come back with some compression numbers...

but don't bother with any of this if your engine oil has water in it.

(in my opinion)

My 1993 jeep grand cherokee laredo idles rough after warm up. it also idels high around 2000 rpm at start up sometimes and needs to be shut off and restarted to calm idle speed. whats is causing the...


usually rough Idle is not noticable at high ildle. Once it is idles normally try Disconnecting one injector at a time. If the idle stays the same than that cylinder is the culprit. Remove that spark. If it is wet than do a compression test. Should read better than 100lbs of compression.If compression is good take a spark plug and hook it into the end of the plug wire.Lay it across the intake,start the car and watch for spark. If you have spark than you probably have a bad injector. A miss will cause the vehicle to idle high. The computer is trying to keep the car from dieing out. Hope this helps. No spark do a tune up.
