Well...my ball park guess on this is just a tune up. The engine light is usually showing a misfire. If the plugs are bad then the cylinder is not igniting the fuel and it is flooding out. With what is here this makes sense to me. Let me know what it does turn out to be.

1994 suburban gmc - no start in heavy rain or high humidity


When was the last time the truck was tuned up? sounds like there is a hair line crack in the distributor cap witch in turn lets moisture get in there and it won't start until it dries back out, the heat from the hair dryer is most likely drying out the moisture in the cap seeing its so close to the throtel body. Do a tune up.

1999 TJ Wrangler/Sah runs rough after warm


we have the same problem on our 2004 dakota. The mechanic says that it could be the exhaust vacuum that needs to be replaced. Also, they also mentioned that sometimes when the catalytic converter is plugged it acts that way also.

Let me know if this helps.

Jetta GLX 1998 (old body), when it rains heavy, car run rough


Sounds like you need new wires and or cap and rotor, had the same problem on my jetta 1.8L when I would drive it in heavy rain it would bog down and misfire. The water blows threw the rad right onto your distributor and wires causing the short (old and cracked or just defective). Try it out I'm sure that will fix it.

Check engine light/rough acceleration


Dear atomicboy488,

A lot of Rain=Possible Water in the Gas=Erratic Running!
This sounds like it may be as simple as cleaning the water or gunk out of the gas tank which is what I always do 1st because it's easy and inexpensive.
If your fuel is contaminated with gunk, grime, WATER and/or bottom junk like rust this will cause stalling AND ROUGH ACCELERATION!
Try spraying a can of starter fluid in the air intake and see if it runs! If it does, it's most likely bad fuel or clogged injectors so....
Fill the tank with High Test, Add some DRYGAS and a good fuel system cleaner or 2 or 3 and this should dissolve all the gunk and clean the injectors! Read & follow the cans' instruction carefully.
If this cures the problem never let your gas tank get below 1/4 and especially never run it to empty as this is when the gunk and/or water will enter the system!
Hope this helps!
Good Luck!
